Chapter 1 Introduction
Storage Center Hardware Components A Dell Compellent Storage Center consists of one or two controllers, switches, and one or more enclosures.
Controllers A Storage Center controller provides the central processing capability for the Storage Center Operating System (OS), application software (Storage Center System Manager), and managing RAID storage. A Storage Center can be configured with a single controller (single‐controller Storage Center) or a pair of controllers (dual‐controller Storage Center). In a dual‐controller Storage Center configuration, the pair of controllers must be the same controller model. IO cards in the controller provide communication with drive enclosures and servers that use the storage. Controllers provide two types of IO ports:
Front‐end ports: Hosts, servers, or Network Attached Storage (NAS) appliances access storage by connecting to controller Fibre Channel IO cards, FCoE IO cards, or iSCSI IO cards through one or more Fibre Channel or Ethernet network switches. Ports for these connections are located on the back of the controller, but are designated as front‐end ports.
Back‐end ports: Enclosures, which hold the physical drives that provide back‐end storage, connect directly to the controller. Fibre Channel and SAS transports are supported through ports designated as back‐end ports. Back‐end ports are in their own private network between the controllers and the drive enclosures.
Switches Dell Compellent offers Fibre Channel (FC) and iSCSI switches and IO cards as part of the total Storage Center product package. Switches provide robust connectivity to servers, allowing for the use of multiple controllers and redundant transport paths. Cabling between the controller IO cards and switches (and servers) is referred to as front‐end connectivity.
Enclosures Enclosures house and control drives that provide storage. Enclosures are connected directly to controller IO cards. These connections are referred to as back‐end connectivity.
2
New Storage Center deployments use 6 GB Serial Attached SCSI (SAS) disk enclosures.
Fibre Channel Switched Bunch of Disks (SBOD) and Serial Advanced Technology Attachment (SATA) enclosures are supported for existing Storage Centers and for controller migrations only (for example, upgrading an existing Storage Center by migrating from a CT‐SC040 controller to an SC8000 controller).

Storage Center Architecture Options
Storage Center Architecture Options The Dell Compellent Storage Center can be deployed in a variety of configurations:
Single Controller, Single Enclosure
Single Controller, Multiple Enclosures
Dual Controller, Single Enclosure
Dual Controller, Multiple Enclosures
Figure 1. Storage Center Architectures Additionally, Storage Center sites can be co‐located or remotely connected and continue to share and replicate data between sites. Replication is used to duplicate volume data to support a Disaster Recovery Plan or to provide rapid local access to a remote data volume. Typically, data is replicated remotely to safeguard against local or even regional data threats as part of an overall Disaster Recovery Plan.

Communication Links
Front End Front‐End connectivity provides connections from servers to controllers using either Ethernet (iSCSI) or Fibre Channel switches. Front‐End connectivity also supports all replication traffic.
iSCSI connections provide reads and writes from a server to a controller through an Ethernet switch.
Fibre Channel over Ethernet (FCoE) uses the FCoE protocol for data on the front end for lossless transmission of data.
Fibre Channel (FC) connections on the front end are used to provide reads and writes from a server to a controller.
Back End Back‐end connectivity is strictly between the controllers and enclosures. The following protocols are supported to communicate with the enclosures.
SAS uses a point‐to‐point switched top topology on four lanes. Each lane can perform concurrent IO transactions at 6 Gb/sec. (Transfer speeds for earlier versions are 3 Gb/ sec.)
Fibre Channel connections were used on the back end for CT‐SC040 controllers. Fibre Channel IO cards can be migrated from CT‐SC040 controllers to SC8000 controllers.
System Administration The following connections are used for communicating with computers outside of Storage Center:
Serial: Used for initial configuration and other service‐related tasks.
Ethernet: Used for administration and IPC between the controllers.
ETH 0 port: Configuration, administration, and management of a Storage Center.
ETH 1 port: Inter‐Process Communications (IPC) between controllers. Note: The Ethernet ports on the back of the controller can operate at 10 Mb , 100 Mb or 1 Gb. These ports are not used for server or enclosure connectivity. For optimal performance, connect to the port using 1 Gbps.
Dell Compellent
iDRAC: Provides access to the Integrated Dell Remote Access Controller (iDRAC) for integrated peer controller management through a dedicated 1 Gb Ethernet port.

Chapter 1 Introduction
Caution: The power supplies must be of the same input type and have the same maximum output power. Mismatched power supplies result in an error condition. Caution: AC power supplies support both 220 V and 110 V input voltages. When two identical power supplies receive different input voltages, they can output different wattages and trigger a mismatch. Caution: When correcting a power supply mismatch, replace only the power supply with the flashing indicator. Swapping the opposite power supply to make a matched pair can result in an error condition and unexpected controller shutdown.
SC280 SAS Enclosures SAS enclosures hold drives for data storage and connect to the controllers through back‐end ports. The Storage Center SC280 is a 5U size 6 GB SAS enclosure. The SC280 enclosure supports up to 84 hard drives installed in two drawers of 42 drives each. The SC280 enclosures also contain two power supply units, five cooling fan modules, and two redundant enclosure management modules (EMMs). The following requirements apply to SC280 enclosures:
12
SC280 enclosures cannot be connected to the same chain as any other enclosures.
Each chain supports a maximum of two SC280 enclosures.
A SAS IO card can support mixed chains (for example, a chain of SC280 enclosures, and a chain of SC200 enclosures), however the enclosures must all be 6 GB.
Controllers must be running Storage Center OS 6.4.1 or later to detect SC280 enclosures.

SC280 EMM Features and Indicators SC280 enclosures include two Enclosure Management Modules (EMM) in two interface slots. Each EMM IO Module includes an EEPROM that holds data describing the function and capability of the EMM module. Each EMM module can discover the type and capabilities of its partner EMM module within the enclosure. Incompatible configurations result in an enclosure system alarm. Each port has four separately arbitrated physical lanes. A green LED indicates the status of each lane. The IO Module and Fault indicators provide status as described below. 1

Safety Precautions To avoid injury and damage to the equipment, always follow these safety precautions. If equipment described in the document is used in a manner not specified by Dell Compellent, the protection provided by the equipment may be impaired. For your safety and protection, observe the following rules: Note: See the safety and regulatory information that shipped with each Storage Center component. Warranty information may be included within this document or as a separate document.
Electrical Safety Precautions Always follow electrical safety precautions to avoid injury and damage to the equipment.
32
Provide a suitable power source with electrical overload protection. All components in the Storage Center must be grounded before applying power. Make sure that there is a safe electrical earth connection to power supply cords. Check the grounding before applying power.
The plugs on the power supply cords are used as the main disconnect device. Make sure that the socket outlets are located near the equipment and are easily accessible.
Know the locations of the equipment power switches and the roomʹs emergency power‐ off switch, disconnection switch, or electrical outlet.
Storage Center SC8000 Controller Deployment Guide
Safety Precautions
Do not work alone when working with high‐voltage components.
Do not use mats designed to decrease electrostatic discharge as protection from electrical shock. Instead, use rubber mats that have been specifically designed as electrical insulators.
Do not remove covers from the Power Control Module (PCM). Disconnect the power connection before removing a PCM from the enclosure.
Do not remove a faulty PCM unless you have a replacement model of the correct type ready for insertion. A faulty PCM must be replaced with a fully operational module within 24 hours.
Permanently unplug the enclosure before you move it or if you think it has become damaged in any way. When powered by multiple AC sources, disconnect all supply power for complete isolation. Warning: Disconnect power from the controller when removing or installing components that are not hot‐swappable. When disconnecting power, first power down the controller using the Storage Center System Manager and then unplug the power cords from all the power supply modules in the controller.
General Safety Precautions To avoid injury and damage to the equipment, always follow general safety precautions.
Keep the area around the chassis clean and free of clutter.
Place the chassis cover and any system components that have been removed away from the controller or on a table so that they are not in the way of foot traffic.
While working on the controller, do not wear loose clothing such as neckties and unbuttoned shirt sleeves, which can come into contact with electrical circuits or be pulled into a cooling fan.
Remove any jewelry or metal objects from your body because they are excellent metal conductors that can create short circuits and harm you if they come into contact with printed circuit boards or areas where power is present.
Do not lift an enclosure by the handles of the Power Cooling Modules (PCMs). They are not designed to hold the weight of the entire enclosure, and the enclosure cover may become bent.
Before moving an enclosure, remove the PCMs to minimize weight.
In order to comply with applicable safety, emission, and thermal requirements, do not remove bay covers from enclosures. Make sure that all bays are populated with plug‐in modules.
Do not remove bay covers or drives until ready to replace them. Warning: To avoid injury, do not attempt to the lift a controller or enclosure by yourself. Always get assistance when lifting the controller. Caution: Do not operate the controller without the cover, except when replacing cooling fans. Warning: The memory modules may be hot for several minutes after the controller has been powered down. Wait for the memory modules to cool before handling them.
Dell Compellent
33
Chapter 2 Install the Hardware
Caution: To ensure proper controller cooling, memory module blanks must be installed in any memory socket that is not occupied. Warning: To prevent eye damage, do not stare into the laser beam aperture of an SFP+ transceiver.
Electrostatic Discharge Precautions To avoid injury and damage to the equipment, always follow electrostatic discharge (ESD) precautions t Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into contact with each other. The resulting electrical discharge can damage electronic components and printed circuit boards. Follow these guidelines to protect your equipment from ESD:
34
It is recommended that you always use a static mat and static strap while working on components in the interior of the controller.
Observe all conventional ESD precautions when handling plug‐in modules and components.
Use a suitable ESD wrist or ankle strap.
Avoid contact with backplane components and module connectors.
Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for use.

Install IO Cards the Controller(s)
Install IO Cards the Controller(s) Before you mount the controller(s) in a rack, install the IO cards.
Open the Cover Open the cover to gain access to the inside of the controller. Caution: Do not operate the controller without the cover, except when replacing cooling fans. Caution: Do not slide the controller into a rack with the cover open. Riser 2 contains a chassis intrusion detection switch that can be easily damaged when sliding a controller into the rack with the cover open. 1 Rotate the latch release lock counter clockwise to the unlocked position. 2 Lift the latch on top of the controller and slide the cover back. 3 Grasp the cover on both sides, and carefully lift the cover away from the controller. 2

Install IO Cards the Controller(s)
Install IO Cards Install the IO cards in the controller(s) based on the IO card priority rules. For dual‐ controller systems, install IO cards in the same locations in both controllers.
Determine Where IO Cards Should Be Installed The following table provides guidelines for installing IO cards to ensure proper cooling and mechanical fit. Install IO cards using the card priority and slot priority order indicated. Populate the slots as follows:
Install low‐profile IO cards in slots 3 through 1. After filling these slots, low‐profile cards may be installed in slots 4, 5, and 6 when used with the adaptive bracket.
Install full‐height IO cards beginning in slot 6, followed by slot 5, then slot 4 if needed.
Slot 7 is reserved for the Cache Card. Note: Low‐profile IO cards are shipped with an adaptive full‐height bracket that must be installed to use the IO card in a slot designed for a full‐height IO card. When a low‐profile card is installed in a full‐height slot the ports are reversed, so port number 1 is on the right. Note: To use Multi‐VLAN Tagging (MVLAN) install a Chelsio 10 Gb iSCSI card. MVLAN is managed in Enterprise Manager.

5U Enclosures The 5U enclosures can weigh up to 131 kg (288 lb) and should be installed in the lower portion of the rack to ensure rack stability. When installed in a rack, the SC280 enclosure extends 36 in. from the front rack posts to the back of the chassis. Rack modifications may be required to avoid blocking PDUs or to allow proper strain relief for SAS cables. Contact Dell Technical Support Services if site preparation has not already been done. Warning: A fully configured SC280 enclosure weighs up to 130.7 kg (287.5 lb). An unpopulated enclosure weighs 62 kg (137 lb). To avoid injury, always lift with two people, and use lifting straps when required. If installed above the lower 20U of a rack, a customer‐provided mechanical lift must be used.
Prerequisites Make sure that the site has the following:
208 V power from an independent source or a rack power distribution unit with a UPS. (110 V power will not work.)
A 5U space in the lower 20U of the rack. If the enclosure is to be installed above the 20U mark (not recommended), a customer‐provided mechanical lift is required.
Power Distribution Unit (PDU) outlets must be type IEC‐320‐C19, with a minimum output Amperage of 20A per connection.
Steps Mount the SC280 enclosure into the rack using mounting rails, and optionally secure with brackets to prevent tipping. 1 Mount the controller(s) in a rack. See the instructions included with the rail kit for detailed steps. 2 Mount the rails in the rack according to instructions included in the rail kit. Warning: When unpacking the 5U enclosure, two people using lift straps are required to avoid injury. 3 Mount the enclosure onto the rack rails, using two people to lift the enclosure into position. 4 Install Hold Down Brackets (HDBs). a Secure the fixing screws to the rear of the enclosure. b Secure the HDBs to the rear of the rack.

Install Drives in SC280 Enclosures The SC280 enclosure supports up to 84 3.5‐inch hard drives installed in two drawers within the enclosure. Hard drives connect to the backplane using Disk Drive in Carrier (DDIC) hard drive carriers. Caution: If the enclosure operates for too long (depending on altitude) with drive drawers open, the enclosure can overheat, causing potential drive failure and data loss. Such use may invalidate the warranty.
Installing Drives Follow these requirements when installing drives in the enclosure.
Any row with drives installed must be filled entirely (14 drives).
The minimum number of drives in an enclosure is 14 (one row).
The number of populated rows between drawers must not differ by more than one.
Populate rows beginning at the front of the enclosure and moving to the rear.
For a new installation, follow these recommendations for populating 42‐drive enclosures.
14 drives in top drawer, front row
14 drives in bottom drawer, front row
14 drives in top drawer, middle row
Steps Caution: Removing a drive from the DDIC can damage the DDIC. Do not remove drives from DDICs. 1 Lower the DDIC into the slot. 2 Push and hold down the DDIC and slide it toward the back of the enclosure until the DDIC latches to the backplane. 3 After all drives are installed, close the drawer. 4 When the enclosure is turned on, make sure that the drive LEDs are not lit, indicating normal conditions. Caution: When the enclosure turns off, the disks continue to spin after losing power. To avoid damage to the disk, wait for the disk to stop spinning (approximately 10 seconds after shut down) before pulling the disk from the enclosure.

Connect the Back End Enclosures are connected to controllers using SAS, a point‐to‐point switched topology on four lanes. Each lane can perform concurrent IO transactions at 6 Gb/sec. Dell Compellent recommends connecting the SAS drive enclosures to the controller(s) using the most redundant options that are available.

SAS Enclosure Cabling Guidelines Multiple SAS enclosures are connected to a controller by cabling the enclosures in series. A series of interconnected enclosures is referred to as a chain. Each chain can contain up to 168 6 Gbps SAS drives. A SAS chain begins at an initiator port in a controller IO card and connects to the first enclosure. Subsequent enclosures are connected in series. For single‐controller Storage Centers, the chain ends at the last enclosure. For dual‐controller Storage Centers, the chain ends in a target port in the opposite controller.
SAS Redundancy Redundant SAS cabling ensures that in the event an IO Card or port fails, IO continues to flow through the remaining functioning path(s). For dual‐controller Storage Centers, redundant cabling also provides protection for controller failures. To achieve redundancy, each SAS chain is made up of two paths that are referred to as the A side and B side.

Chapter 3 Connect the Back End
SC8000 SAS Port Types There are two types of controller SAS ports: initiator only and initiator/target. SAS chains begin with an initiator port. As shown in the following figure, ports 1–2 (circled in blue) on SAS IO cards are initiator only, and ports 3–4 (circled in red) are initiator/target. 1
2
Figure 52. Controller SAS Port Types 1 Initiator Only (Ports 1–2) 2 Initiator/Target (Ports 3–4)
Connect IPC for Dual-Controller Storage Centers If you are configuring a dual‐controller Storage Center, connect the controllers with a Category (Cat) 6 Ethernet cable. If the Storage Center only uses a single SAS chain, you must also interconnect the controllers with additional SAS connections to make sure that sufficient IPC bandwidth is available.
56
Storage Center SC8000 Controller Deployment Guide
Connect IPC for Dual-Controller Storage Centers
Connect the Controllers with Ethernet In a dual‐controller Storage Center, the ETH 1 ports of the controllers must be directly connected to each other. 1 Connect the ETH 1 (port 1) on one controller to the same port on the second controller. Use a Cat 6 cable for this connection. Note: Storage Center currently runs the 10 Gb ports at 1 Gb speed. Use a Cat. 6 cable to ensure that a hardware change is unnecessary when 10 Gb rates are implemented.

Connect IPC for Dual-Controller Storage Centers
Connect the Controllers with SAS If the Storage Center has only a single SAS chain, interconnect the controllers with additional SAS connections to provide redundancy and to make sure that sufficient IPC bandwidth is available. If two or more enclosure chains exist, IPC Direct Connect is optional. If the Storage Center requires SAS IPC, add cabling between the initiator and target ports on the controllers. 1 Controller A: IO Card port 2 (initiator) → Controller B: IO Card port 4 (target). 2 Controller B: IO Card port 2 (initiator) → Controller A: IO Card port 4 (target). 3 Label both ends of each SAS IPC cable. a Locate the IPC labels that shipped with the controller(s).

Connect SC200/SC220 Enclosures This section shows common cabling between the SC8000 controller and SC200/220 SAS enclosures. Locate the scenario that most closely matches the Storage Center you are configuring and follow the instructions, modifying them as necessary. An SC200/SC220 cabling chain can contain up to 168 SAS drives, using either type of enclosure. The maximum number of any one type of enclosure is:
SC200: 14 enclosures
SC220: 7 enclosures
Each SAS IO card supports up to two chains of enclosures. All enclosures attached to the same SAS IO card must be running at the same speed (all 6 Gb or 3 Gb). SC200/220 SAS enclosure chains are cabled as follows.

Connect SC280 Enclosures This section shows common cabling between the SC8000 controller and SC280 SAS enclosures. Locate the scenario that most closely matches the Storage Center you are configuring and follow the instructions, modifying them as necessary. A cabling chain for the SC280 can contain up to two enclosures of 84 SAS drives each (168 drives total). Each chain must contain the same type of enclosures, such as all SC280. Do not mix enclosure types in a chain. Each SAS IO card supports up to two chains of enclosures. All enclosures attached to the same SAS IO card must be running at 6 Gb. SC280 enclosure chains are cabled as follows.
Side A: Enclosures are connected from B port to A port, using the left EMMs.
Side B: Enclosures are connected from A port to B port, using the right EMMs.
Path
High-Level Steps
Chain 1: Side A 1 Connect controller port 1 to the first enclosure, left EMM, port C. 2 Connect the remaining enclosures in series from B port to A port using the left EMMs. 3 If the Storage Center has dual controllers, connect the last enclosure, left EMM, port C to the second controller, port 3. Chain 1: Side B 1 Connect controller port 3 to the last enclosure, right EMM, port C. 2 Connect the remaining enclosures in series from B port to A port using the right EMM. 3 If the Storage Center has dual controllers, connect the top enclosure, right EMM, port C to the second controller, port 1.
Note: The cabling illustrations in this chapter refer to enclosures as Enclosure 1, Enclosure 2, and so on. The numbers shown in the illustrations may not match the Index number assigned by the System Manager. Storage Center assigns an Index only after the system is powered up and at least one drive is assigned to a Disk Folder.

Label the Back-End Cables
Label the Back-End Cables Label the back‐end cables that connect controllers to enclosures to indicate the chain number and side (A or B). Pre‐made labels are provided for SC200/220 enclosures. Labels are not provided for EN‐SASx6x12/24 enclosures, so labels must be created manually for cables that connect to those enclosures. Note: Cables that connect one enclosure to another do not need to be labeled.
Prerequisites If the Storage Center has EN‐SASx6x12/24 enclosures, you must have a label maker, or four blank labels and a writing utensil.
Steps 1 Locate or create labels for the back‐end cables.
EN‐SASx6x12/24 enclosures: Create labels that label the purpose (Backend), chain number, and side (A or B). Example: Backend 1A
SC200/220 enclosures: Locate the back‐end cable labels that shipped with the enclosures. The pre‐made labels include the purpose (Backend), chain number, and side (A or B).

Connect the Front End Front‐end cabling refers to connections between the controller and the server. Front‐end connections can be made using iSCSI, Fibre Channel, or Fibre Channel over Ethernet (FCoE). Dell Compellent recommends connecting servers to the controller(s) using the most redundant options available.

Types of Redundancy for Front-End Connections Front‐end redundancy is achieved by eliminating single points of failure that could cause a server to lose connectivity to the Storage Center. Depending on how the Storage Center is configured, the following types of redundancy are available.
Path redundancy: When multiple paths are available from a server to a Storage Center, a server configured for multipath IO (MPIO) can use multiple paths for IO. If a path fails, the server continues to use the remaining active path(s).
Controller redundancy: If one controller fails in a dual‐controller Storage Center, the front‐end ports fail over to the functioning controller. Both front‐end connectivity modes (legacy mode and virtual port mode) provide controller redundancy.
Port redundancy: In virtual port mode, if a port goes down because it is disconnected or there is a hardware failure, the port can fail over to another functioning port in the same fault domain. Port redundancy is available for single‐controller and dual‐ controller Storage Centers operating in virtual port mode.

Chapter 4 Connect the Front End
Multipath IO Multipath IO (MPIO) allows a server to use multiple paths for IO if they are available. MPIO software offers redundancy at the path level. MPIO loads as a driver on the server, and typically operates in a round‐robin manner by sending packets first down one path and then the other. If a path fails, MPIO software continues to send packets down the functioning path. MPIO is operating‐system specific.
MPIO Behavior for Dual-Controller Storage Centers When MPIO is configured, a server can send IO to both controllers. However, a single volume is owned by one controller at a time. Even if there are active paths from a server to both controllers, IO for a single volume is always processed by one controller. This limitation only applies to individual volumes. If a server has two or more volumes owned by different controllers, the server can send IO to both controllers.
MPIO Configuration Instructions for Servers To use MPIO, configure MPIO on the server prior to connecting the Storage Center front end. Depending on the operating system, this may require installing MPIO software or may only require setting server options. To configure MPIO on a server, see the Dell Compellent document that corresponds to the server operating system. Operating System

Front-End Connectivity Modes Storage Center uses either legacy mode or virtual port mode to transport data to servers that use SAN storage. In legacy mode, front‐end IO ports are configured in pairs of primary and reserved ports. In virtual port mode, all ports are active, and if one port fails the load is distributed between the remaining ports within the same fault domain. Note: In Legacy mode, reserve ports and primary ports reside on separate controllers, providing controller‐level failover only. Legacy mode does not provide port‐level failover. The front‐end connectivity mode is configured independently for Fibre Channel and iSCSI. Both transport types can be configured to use the same mode or different modes to meet the needs of the network infrastructure. For example, a Storage Center can be configured to use virtual port mode for FC and legacy mode for iSCSI.

Front-End Connectivity Modes
Note: Dell Compellent strongly recommends using virtual port mode unless the network environment does not meet the requirements for virtual port mode.
Virtual Port Mode Virtual port mode provides port and controller redundancy by connecting multiple active ports to each Fibre Channel or Ethernet switch. In virtual port mode, each physical port has a WWN (World Wide Name), and is also assigned an additional virtual WWN. Servers target only the virtual WWNs. During normal conditions, all ports process IO. If a port or controller fails, a virtual WWN can be moved to another physical WWN in the same fault domain. When the failure is resolved and ports are rebalanced, the virtual port returns to the preferred physical port. Virtual port mode provides the following advantages over legacy mode:
Increased performance: Because all ports are active, additional front‐end bandwidth is available without sacrificing redundancy.
Improved redundancy: Ports can fail over individually instead of by controller.
Simplified iSCSI configuration: Each fault domain has an iSCSI control port that coordinates discovery of the iSCSI ports in the domain. When a server targets the iSCSI port IP address, it automatically discovers all ports in the fault domain.
Fault Domains in Virtual Port Mode Fault domains group front‐end ports that are connected to the same Fibre Channel fabric or Ethernet network. Ports that belong to the same fault domain can fail over to each other because they have the same connectivity. The following requirements apply to fault domains in virtual port mode:
A separate fault domain must be created for each front‐end Fibre Channel fabric or Ethernet network.
A fault domain must contain a single type of transport media (FC or iSCSI, but not both).
Dell Compellent recommends configuring at least two connections from each controller to each Fibre Channel or Ethernet network (fault domain).
Requirements for Virtual Port Mode The following requirements must be met to configure a Storage Center in virtual port mode.

Storage Center SC8000 Controller Deployment Guide
Front-End Connectivity Modes
Legacy Mode Legacy mode provides controller redundancy for a dual‐controller Storage Center by connecting multiple primary and reserved ports to each Fibre Channel or Ethernet switch. In legacy mode, each primary port on a controller is paired with a corresponding reserved port on the other controller. During normal conditions, the primary ports process IO and the reserved ports are in standby mode. If a controller fails, the primary ports fail over to the corresponding reserved ports on the other controller. This approach ensures that servers connected to the switch do not lose connectivity if one of the controllers fails. For optimal performance, the primary ports should be evenly distributed across both controllers. When possible, front‐end connections should be made to separate controller IO cards to improve redundancy.
Fault Domains in Legacy Mode Each pair of primary and reserved ports is grouped into a fault domain in the Storage Center software. The fault domain determines which ports are allowed to fail over to each other. The following requirements apply to fault domains in legacy mode on a dual‐controller Storage Center:
A fault domain must contain a one type of transport media (FC or iSCSI, but not both).
A fault domain must contain one primary port and one reserved port.
The reserved port must be located on a different controller than the primary port. Note: For a single‐controller Storage Center, only one fault domain is required for each transport type (FC or iSCSI) because there are no reserved ports.
Requirements for Legacy Mode The following requirements must be met to configure a Storage Center in legacy mode. Requirement
Description
Controller front‐end ports
Each controller must have enough front‐end ports to connect two paths to each Fibre Channel or Ethernet switch.

Chapter 4 Connect the Front End
Fibre Channel Zoning When using Fibre Channel for front‐end connectivity, zones must be established to ensure that storage is visible to the servers. Plan the front end connectivity using zoning concepts discussed in this section before starting to cable the controller. Zoning can be applied to either the ports on switches or to the World Wide Names (WWNs) of the end devices. Zones should be created using a single initiator (using physical WWNs) and multiple targets (using virtual WWNs). In a dual‐controller configuration, the virtual WWNs from each controller must be included in the zone with each host’s WWN. Note: For virtual port mode, WWN zoning is recommended.
WWN Zoning Guidelines When WWN zoning is configured, a device may reside on any port or change physical ports and still be visible because the switch is seeking a WWN. Connectivity Type
Guidelines
Legacy mode
• Include all Storage Center front‐end WWNs or ports in a single zone. • Create server zones that contain a single initiator and multiple targets, and which include the server HBA WWN.
Virtual port mode
• Include all Storage Center virtual WWNs in a single zone. • Include all Storage Center physical WWNs in a single zone. • Create server zones that contain a single initiator and multiple targets (Storage Center virtual WWNs), and which include the server HBA WWN.
Fibre Channel replication
• Include all Storage Center physical WWNs from System A and B in a single zone. • Include all Storage Center physical WWNs of System A and the virtual WWNs of System B on the particular Fabric. • Include all Storage Center physical WWNs of System B and the virtual WWNs of System A on the particular Fabric. Note: Some ports may not be used or dedicated for replication, however ports that are used must be in these zones.
Port Zoning Guidelines When port zoning is configured, only specific switch ports are visible. If a storage device is moved to a different port that is not part of the zone, it is no longer visible to the other ports in the zone. Connectivity Type

Chapter 4 Connect the Front End
Virtual Port Mode with Single-Network iSCSI Connect virtual port mode iSCSI to a single network if only one Ethernet switch is available and you want to protect against port or controller failure. In this configuration, there is one fault domain because there is a single network. Each controller is connected to the fabric by at least two iSCSI connections to provide port redundancy. If a single port fails, its virtual port fails over to another port. If a controller fails, the virtual ports on the failed controller move to ports on the other controller. This configuration is vulnerable to switch failure.
Prerequisites
Each controller must have two available iSCSI front‐end ports.
The requirements for virtual port mode must be met.
Steps 1 Connect each server to the iSCSI network. 2 Connect fault domain 1 (shown in orange) to iSCSI network 1.

Virtual Port Mode with Dual-Network iSCSI Use two networks with virtual port mode to prevent an Ethernet switch failure or controller failure from causing an outage. In this configuration, there is one fault domain for each iSCSI network. Each controller is connected to both Ethernet networks by two iSCSI connections. If a single port fails, its virtual port fails over to another port in the same fault domain. If a controller fails, the virtual ports on the failed controller move to ports on the other controller in the same fault domain.

If the prompt (>) is not displayed, see Troubleshooting the Serial Connection on page 205. 2 Set the HSN and SSN using the SSN(s) provided in the pre‐installation documents. Caution: The following commands are for new installations only. Running the cs purge all command on an existing Storage Center controller deletes the existing configuration and can make data inaccessible.
Controller 1: Set the HSN and SSN to the lower SSN. shellaccess developer platform init hsn set [lower SSN] platform init ssn set [lower SSN] cs purge all -reset
Controller 2: (Dual‐controller only) Set the HSN and SSN to the higher SSN. shellaccess developer platform init hsn set [higher SSN] platform init ssn set [higher SSN] cs purge all -reset
The controller takes several minutes to reboot. The controller may reboot more than once — this is normal. 3 When the reboot is complete, verify that the table that is displayed ends with: 2 1 Finish
4 Verify the new settings by running the controller show command. Note: Although entered in decimal, the new HSN and SSN values are returned in hexadecimal. 5 Record the factory default eth1 address. For dual‐controller Storage Centers, the eth1 address from Controller 2 is needed during the setup process.
Set Controller IP Addresses Storage Center controllers use static IP addresses. Configure an IP address for the management interface (eth0), specify one or more DNS servers, and set the domain name to which the Storage Center belongs.
eth0 supports system login and access for the software. It is used to send emails, alerts, SNMP traps, and Phone Home data.
eth1 is used for dedicated Inter‐Process Communication (IPC) between controllers in a dual‐controller Storage Center. Because eth1 is directly connected to the other controller, no default gateway is required. Do not change the eth1 address unless both controllers were factory configured with the same address or the customer requests the change. The eth1 address cannot reside in the same subnet as eth0.
Dell Compellent

Chapter 5 Set up the Storage Center Software
Note: If configuring a dual‐controller Storage Center, perform this task for both controllers. 1 Run the following command to configure the management interface (etho). controller ipconfig eth0 [IP address] [netmask] [gateway]
Example: controller ipconfig eth0 172.31.1.101 255.255.0.0 172.31.0.1
2 Run the following command to specify one or more DNS servers. controller dnsserver [DNS server 1 IP address] [DNS server 2 IP address]
Example: controller dnsserver 172.31.0.50 172.31.0.60
3 Run the following command to specify the domain to which the Storage Center belongs. controller domainname [domain name]
Example: controller domainname corp.dom
4 Verify the changes to the network settings by running the following command: controller show
Manage the iDRAC IP Address The SC8000 controller includes the Integrated Dell Remote Access Controller (iDRAC7) that is factory configured for Dynamic Host Configuration Protocol (DHCP). The iDRAC can be left with the original configuration or it can be assigned a static IP address. Note: To use the iDRAC in a non‐DHCP environment, a static IP address must be set.
To see if the iDRAC is set to use a static IP address or DHCP, run the following command: platform bmc get source
To see what IP address is assigned to the iDRAC, run the following command: platform bmc show
To set the iDRAC to a static IP address, run the following commands: platform bmc set ip [IP address] platform bmc set netmask [netmask] platform bmc set gateway [gateway]
Example: platform bmc set ip 10.0.0.12 platform bmc set netmask 255.255.255.0 platform bmc set gateway 10.0.0.1
Note: On a dual‐controller Storage Center, change the iDRAC IP address on both SC8000 controllers.
To set the iDRAC to use DHCP, run the following command: platform bmc set source DHCP
Note that DHCP must be entered in all caps. 126

Update Storage Center OS to the latest version.
If the Storage Center has internet connectivity, use the System Manager to download and install the latest Storage Center OS. For instructions, see the Storage Center Software Update Guide.
If the Storage Center does not have internet connectivity, use the Storage Center Maintenance CD to perform the upgrade. See the Storage Center Maintenance CD Instructions document for details.
4 After updating the Storage Center OS, check for additional updates again. Enclosure firmware updates may not install with the OS update, since Storage Center does not recognize some new hardware until after the OS is installed. Note: When using the network to upgrade Storage Center to OS 6.4.1 for an SC280 enclosure, the enclosure firmware updates must be installed separately after Storage Center OS 6.4.1 is installed. Check the Update Details window for Enclosure updates marked Deferrable, and install them now. The enclosure firmware updates may take 20‐30 minutes. Do not interrupt the update after it has started. 5 If you are configuring a dual‐controller Storage Center, perform steps 1–4 on the second controller. Firmware upgrades should have installed when the first controller was updated. 6 After both controllers are upgraded to the latest version, log out of System Manager and log back in to continue with the setup process (see Step 3 on page 128).

If Self‐Encrypting Drives (SEDs) that are Federal Information Processing Standard (FIPS) 140‐2 certified are detected, Storage Center formats the drives as if Secure Data will be used, and you are asked whether to create a Secure Data folder. See About Secure Data on page 131.
If the No disks could be found message is displayed, see Troubleshooting Enclosures on page 205.
Storage Center SC8000 Controller Deployment Guide
Complete the Startup Wizard
About Secure Data Secure Data is a licensed feature that provides data‐at‐rest encryption with key management. Using Secure Data to manage SEDs requires an external key management server. If a key management server has not been configured or is unavailable, you can manage FIPS SEDs into a Secure Data folder, however the disks remain in a pending state until the key management server is available. Each FIPS disk in Storage Center has an internal Media Encryption Key (MEK). The key resides on the disk, providing encryption for data written to the disk and decryption for data as it is read from the disk. Destroying the key makes any data on the disk immediately and permanently unreadable, a process referred to as a crypto erase. When you add an SED to, or release an SED from a Secure Data folder, the MEK is destroyed and a new key is generated. This allows the disk to be reused, although all previous data is lost. Note: Because disks that contain user data cannot be moved from a Secure Data folder, Storage Center does not crypto erase disks that contain user data. To protect data at rest, all SEDs in a Secure Data disk folder lock when power is removed (Lock on Reset enabled). When power is removed from the drive, the drive cannot be unlocked without access to the authority credential stored in the key management server.

The hot spare disk must be as large or larger than the largest disk of its type in the disk folder. For redundancy, there must be at least one hot spare for each enclosure. In general, System Manager uses the following best practices in designating hot spares:
For 2U enclosures, one spare disk for every disk class (10K, 7.5K, and so on).
For 5U enclosures, one spare disk for every 21 disks, however no single row will contain more than one spare disk.

b Configure the Tier Redundancy for each tier. The redundancy level for each tier defaults to either single redundant or dual redundant depending upon the disks expected to be found in the tier. If a tier contains at least six managed disks of which one is 900 GB or greater, then that tier and all tiers below it are set to dual redundant storage by default. If a tier contains at least six managed disks of 1.8 TB or greater, then that tier and all tiers below it are set to dual redundant storage and cannot be changed. Single redundant storage protects against the loss of any one drive.

Appendix A Adding or Removing an Enclosure
Adding SC280 Enclosures Use caution when adding an enclosure to a live Storage Center system to preserve the integrity of the existing data. This section describes two methods of adding enclosures:
Add an enclosure in a new chain: by adding enclosures to available ports on the controller’s IO cards. The current configuration is undisturbed. Creating a new chain is the safest way to increase storage capacity. When you have multiple chains, you should have at least two IO cards in each controller.
Add an enclosure to an existing chain by removing one side of the chain causing traffic to route to the remaining side. Connect the new enclosure into the disconnected side of the chain.
Adding an SC280 Enclosure in a New Chain This method is safe and non‐intrusive to the existing disks and chains. A second chain creates controller redundancy and so IPC cross‐over cables are not required.
Check Lead Controller Identify the lead controller by checking controller summary information in System Manager. These cabling instructions assume that Controller A is the lead controller. 1 In the Storage Center System Manager, select the Controllers node. 2 In the controller summary pane note which controller is identified as the leader.
Connect the Enclosure 1 Turn on each enclosure being added. When the enclosures spin up, make sure that each front panel enclosure and power status LEDs show normal operation. 2 Connect the A side (Figure 111 on page 176): a Connect Controller A: slot 3, port 2→ Enclosure 2: left, port C. b Connect Controller B: slot 3, port 4→ Enclosure 2: left, port B. 3 Connect the B side (Figure 112 on page 177): a Connect Controller A: slot 3, port 4→ Enclosure 2: right, port B. b Connect Controller B: slot 3, port 2→ Enclosure 2: right, port C. 4 In the Storage Center System Manager, select Storage Management→ System→ Setup→ Configure Local Ports. 5 Make sure that:
Slot and slot ports are Up and the Purpose is set to back‐end.
Target Count equals the number of added drives, demonstrating that the controller recognizes the new enclosures.
6 In the Storage Manager System Tree, confirm the number of enclosures. If there are no managed disks in this system, the System Manager does not assign an Index number. If the system contains a managed disk in any enclosure, the System Manager assigns an index number to the new enclosures. Note: Enclosures must be running the current version of firmware before managing the drives in Storage Center System Manager.

Appendix A Adding or Removing an Enclosure
Adding to an Existing SC280 Enclosure Chain The following example shows how to insert an enclosure into an existing enclosure chain by connecting the enclosure to one side of the enclosure chain at a time. Caution: Before adding an enclosure to an existing chain, make sure that your data is backed up. For maximum protection, add enclosures during a service outage.
Check the Lead Controller Identify the lead controller by checking controller summary information in System Manager. These cabling instructions assume that Controller A is the lead controller. 1 In the Storage Center System Manager, select the Controllers node. 2 In the controller summary pane note which controller is identified as the leader.
Check Current Disk Count Check the current number of drives accessible by the Storage Center to use as a comparison after a new enclosure is added. 1 In the Storage Center System Manager, select Storage Management→ System→ Setup→ Configure Local Ports. 2 Maximize the Configure Local Port wizard so that you can see the Target Count column, and note the number of drives currently viewed by the controllers. This number increases when new enclosures are added.
Add an Enclosure to an Existing Chain Currently in Service When adding enclosures to an existing configuration, add enclosures to the end of the chain. Disconnect the chain one side at a time to maintain drive availability while adding an enclosure.
Connecting the Enclosure to the A Side 1 Disconnect the A‐side cables from the controllers as shown in Figure 113 on page 180.

Adding SC200/220 Enclosures Use caution when adding an enclosure to a live Storage Center system to preserve the integrity of the existing data. This section describes two methods of adding enclosures:
Create a new chain by adding enclosures to available ports on the controller’s IO cards. The current configuration is undisturbed. Creating a new chain is the safest way to increase storage capacity. When you have multiple chains, you should have at least two IO cards in each controller.
Add an enclosure to an existing chain by failing over to one side of the chain and then connecting into the other side of the chain.
Creating a New Chain of SC200/220 Enclosures This method is safe and non‐intrusive to the existing disks and chains. Figure 117 on page 185 shows an example of adding a new chain using the following steps. 1 If there is more than one enclosure in the new chain, cable the enclosures together first. Do not connect the chain to the controller yet. Connect the enclosures: a New Enclosure (3): top, port B → Next Enclosure (4): top, port A. b New Enclosure (3): bottom port B → Next Enclosure (4): bottom, port A. 2 Turn on each of the enclosures being added. When the enclosures spin up, make sure that the front panel enclosure and power status LEDs show normal operation. 3 Connect the Controller: slot 6, port 2 → Enclosure 3: top, port A. 4 In the Storage Center System Manager, select Storage Management→ System→ Setup→ Configure Local Ports. 5 Make sure that:
Slot and slot port (in this case, slot 6, port 2) are Up and the Purpose is set to back‐ end.
Target Count equals the number of added drives, demonstrating that the controller recognizes the new enclosures.
6 In the Storage Manager System Tree, confirm the number of enclosures. 7 Connect last Enclosure (4): bottom, port B → Controller: slot 6, port 4. 8 Verify that the last enclosure has been added as described in steps 4 through 6. 9 If there are no managed disks in this system, the System Manager does not assign an Index number. If the system contains a managed disk in any enclosure, the System Manager assigns an index number to the new enclosures. 10 The Storage Center System Manager informs you that you have new, unassigned disks. from the Storage Management menu, select Disk→ Manage Unassigned Disks to move them to the managed disk folder and add the space to the disk pool. For more information, see the Storage Center System Manager Administrator’s Guide. 11 To redistribute data across all drives, from the Storage Management menu, select Disk→ Rebalance RAID.

Appendix A Adding or Removing an Enclosure
Adding to an Existing SAS Enclosure Chain The following example shows how to insert an enclosure into an existing enclosure chain by connecting the enclosure to one side of the enclosure chain at a time. During this process, one side of the enclosure chain is disconnected, and the Storage Center fails over to the side that remains connected. Caution: Before adding an enclosure to an existing chain, make sure that your data is backed up. For maximum protection, add enclosures during a service outage.
Check the Lead Controller Identify the lead controller by checking controller summary information in System Manager. These cabling instructions assume that Controller A is the lead controller. 1 In the Storage Center System Manager, select the Controllers node. 2 In the controller summary pane note which controller is identified as the leader.
Check Current Disk Count Check the current number of drives accessible by the Storage Center to use as a comparison after a new enclosure is added. 1 From a workstation connected to the network, open the Storage Center System Manager. 2 In the Storage Center System Manager, select Storage Management→ System→ Setup→ Configure Local Ports. 3 Maximize the Configure Local Port wizard so that you can see the Target Count column, and note the number of drives currently viewed by the controllers. This number increases when new enclosures are added. When adding enclosures to an existing configuration, add enclosures to the end of the chain.
Add an Enclosure to an Existing Chain Currently in Service Disconnect the chain one side at a time to maintain drive availability while adding an enclosure. 1 Disconnect the A‐side cables from the controllers as shown in Figure 118 on page 187:
Controller A, slot 6 port 1
Controller B, slot 6 port 3
IO continues through the B‐side cables. 2 Turn on each of the enclosures being added. When the enclosures spin up, make sure that the front panel enclosure and power status LEDs show normal operation. 3 Move the cable from Enclosure 2: top, port B→ Enclosure 4: top, port B. 4 Use new cables to connect the new enclosures to the A‐side cabling (Figure 118 on page 187):
Enclosure 2: top, port B→ Enclosure 3: top, port A.
Enclosure 3: top, port B→ Enclosure 4, top, port A.
Enclosures 3 and 4 are now part of the A side chain and can be connected to Controllers A and B.

Removing Enclosures
Removing Enclosures The following procedure describes how to use Storage Center System Manager to move data off the disks in the enclosure to be removed. For more detailed instructions, see the Storage Center System Manager Administrator’s Guide. Caution: Before you remove an enclosure, make sure that your data is backed up and that all disks to be removed are empty of data.
Release Disks Release disks to remove them from the pool in preparation of removing the enclosure. 1 In the Storage Center tree, expand the Disks node to view the disks in the enclosure. 2 Select all the disks in the enclosure you are removing. 3 From the shortcut menu, select Release Disk. The Release Disk wizard starts. 4 Note the warning and click Yes to continue. The disk is immediately released and a dialog box opens asking if you wish to rebalance RAID devices now, later, or skip balancing. 5 Click Yes. Wait for the rebalance operation to finish. Enclosures with all drives in the unassigned disk folder are now safe to remove.
Remove an SC280 Enclosure These instructions describe how to remove an enclosure from an SC280 enclosure chain. If the configuration has two enclosure chains, you do not need to take a system outage; however, the controller must be able to see all drives through one chain while the other side is down. Caution: To disconnect the A‐side cabling without a system outage, make sure that you first disconnect the A‐side cable from the controller. Disconnecting any other cable first disrupts IO to the enclosure, resulting in a system outage.
Disconnect the A-side Chain Disconnect the enclosure to be removed from the A‐side chain. 1 Disconnect the A‐side cable from Controller B: slot 3, port 3. The B side continues to carry IO while the A side is disconnected (see Figure 124 on page 194). 2 In the Storage Center System Manager, select Storage Management→ System→ Setup→ Configure Local Ports. 3 Make sure that:
Slot and slot ports are Up and the Purpose is set to back‐end.
Target Count equals the number of added drives, demonstrating that the controller recognizes the new enclosures.
4 Remove the cable between: Enclosure 1: left, port B → Enclosure 2: left, port A (see Figure 124 on page 194). 5 Move the cable from Enclosure 2: left, port C → Enclosure 1: left, port A (see Figure 125 on page 195). 6 Reconnect the top cable to Controller B: slot 3, port 3 (see Figure 125 on page 195).
