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. 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 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. Dell Compellent...
Page 14: Communication Links
Chapter 1 Introduction Communication Links A Storage Center controller uses multiple types of communication links for both data transfer and administrative functions. Communication links are classified into three types: front end, back end, and system administration. Figure 2. SC8000 Controller Communication Links Item Description Speed Type Server with Fibre Channel Host Bus 8 Gb or 16 Gb Front End Adapters (HBAs) Fibre Channel Switches 8 Gb or 16 Gb Front End Server with Fibre Channel over Ethernet 10 Gb Front End (FCoE) HBAs or iSCSI HBAs 1 Gb or 10 Gb Ethernet Switches 1 Gb or 10 Gb Front End SC8000 Controller IO card‐dependent SAS Enclosure 6 Gb per channel Back End Note: FC enclosures are supported for ...
Page 15: Front End
 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. iDRAC: Provides access to the Integrated Dell Remote Access Controller (iDRAC) for  integrated peer controller management through a dedicated 1 Gb Ethernet port. Dell Compellent...

Page 22: Sc280 Sas Enclosures
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.

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...

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. Dell Compellent...
Page 66: Sc8000 Sas Port Types
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. 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. Storage Center SC8000 Controller Deployment Guide...
Page 67: Connect The Controllers With Ethernet
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. MGMT MGMT Figure 53.

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.

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. Storage Center SC8000 Controller Deployment Guide...
Page 107: Virtual Port Mode
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 ...

Page 109: Legacy Mode
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 Each controller must have enough front‐end ports to connect two paths to ports each Fibre Channel or Ethernet switch. Multipathing If multiple active paths are available to a server, the server must be configured for MPIO to use more than one path simultaneously.

Page 113: Connect The Front End For A Single-Controller Storage Center
Connect servers without using redundancy if the controller does not have enough front‐ end ports to allow redundant paths to each FC fabric, directly connected FC server, and Ethernet switch. Prerequisites The controller must have an available front‐end port for each FC fabric, Ethernet switch (iSCSI network), and standalone FC server that you want to directly connect. Note: iSCSI servers must be connected to Ethernet switches. An iSCSI server cannot be directly connected to a front‐end iSCSI port on the controller.

Page 115: Connect The Front End For A Dual-Controller Storage Center
Use Fibre Channel and iSCSI to connect servers to the Storage Center. For each transport type, choose a front‐end connectivity mode (legacy mode or virtual port mode), and then connect the servers in a way that meets the requirements of the chosen connectivity mode. Apply cable labels to both ends of each cable. Note: The cabling instructions and diagrams in this section are valid for a particular IO card configuration. If the controllers you are installing contain different IO cards, adjust the cabling accordingly.

Page 141 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. Dell Compellent...

Page 209: Remove An Sc200/Sc220 Enclosure
Remove an SC200/SC220 Enclosure These instructions describe how to remove the top enclosure from a SC200/SC220 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 A: slot 6, port 1. The B side continues to carry IO while the A side is disconnected (see Figure 128 on page 200). 2 In the Configure Local Ports wizard, make sure that the B‐side ports on both controllers are Up and the Target Count recognizes the drives through the B side. 3 Remove the cable between: Enclosure 1: top, port B → Enclosure 2: top, port A (see Figure 128 on page 200). 4 Move the cable from Enclosure 1: top, port A → Enclosure 2: top, port A (see Figure 129 on page 201).
