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.

MPIO loads as a driver on the server. this may require installing MPIO software or may only require setting server options. IO for a single volume is always processed by one controller. 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. Dell Compellent Requirement Description License The Storage Center must be licensed for virtual port mode. Switches Front‐end ports must be connected to Fibre Channel or Ethernet switches; servers cannot be directly connected to controller front‐end ports. 97 Chapter 4 Connect the Front End Requirement Description Multipathing If multiple active paths are available to a server, the server must be configured for MPIO to use more than one path simultaneously. iSCSI networks • NAT must be disabled for iSCSI replication traffic. • CHAP authentication must be disabled. Fibre Channel fabrics • The FC topology must be switched fabric. Point‐to‐point and arbitrated loop topologies are not supported. • FC switches must be zoned to meet the virtual port mode zoning requirements. • FC switches must support N_Port ID Virtualization (NPIV). • Persistent FCID must be disabled on FC switches. Note: AIX servers are not supported. See Also Fibre Channel Zoning on page 102 Example Virtual Port Mode Configuration The following figure shows a dual‐controller Storage Center in virtual port mode connected to a Fibre Channel server with a single fault domain. All ports belong to a single fault domain because they are connected to the same FC switch. Server FC Switch Active Ports Controller A Controller B Figure 88. Virtual Ports Example with FC Note: To use both primary paths simultaneously, the server must be configured to use MPIO. The following table summarizes the failover behaviors for this configuration. Scenario Failover Behavior Normal operating conditions All ports are active and pass IO. 98 Controller A fails Virtual ports on controller A fail over by moving to physical ports on controller B. Controller B fails Virtual ports on controller B fail over by moving to physical ports on controller A. A single port fails The virtual port associated with the failed physical port moves to another physical port in the fault domain. 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. Multipathing If multiple active paths are available to a server, the server must be configured for MPIO to use more than one path simultaneously. Fibre Channel zoning FC switches must be zoned to meet the legacy mode zoning requirements. See Also Fibre Channel Zoning on page 102 Dell Compellent 99 Chapter 4 Connect the Front End Example Legacy Mode Configuration The following figure shows a dual‐controller Storage Center in legacy mode connected to a Fibre Channel server with two fault domains. Fault domain 1 (shown in orange) is comprised of primary port P1 on controller A and reserved port R1 on controller B. Fault domain 2 (shown in green) is comprised of primary port P2 on controller B and reserved port R2 on controller A. Server FC Switch Reserved Port — R1 Primary Port — P1 Primary Port — P2 Reserved Port — R2 Controller A Controller B Figure 89. Legacy Mode Example with FC Note: To use multiple paths simultaneously, the server must be configured to use MPIO. The following table summarizes the failover behaviors for this configuration. Scenario Failover Behavior Normal operating conditions • Primary ports P1 and P2 (both fault domains) pass IO. • Reserved ports R1 and R2 remain in a standby mode until a controller failure. 100 Controller A fails In fault domain 1, primary port P1 fails over to reserved port R1. Controller B fails In fault domain 2, primary port P2 fails over to reserved port R2. A single port fails The port does not fail over because there was no controller failure. If a second path is available, MPIO software on the server provides fault tolerance by sending IO to the functioning port in the other fault domain. Storage Center SC8000 Controller Deployment Guide Note: In Legacy mode. MPIO software on the server provides fault tolerance.

Dell Compellent 101 .Front-End Connectivity Modes Failover Behavior for Legacy Mode and Virtual Port Mode Legacy mode and virtual port mode behave differently during failure conditions because they use different mechanisms to provide fault tolerance. Scenario Virtual Port Mode Normal operating conditions All ports are active and pass IO. 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 Guidelines Legacy mode or virtual port • Include all Storage Center front‐end ports. mode • Create server zones which contain all Storage Center front‐end ports and a single server port. Fibre Channel replication 102 Include all Storage Center front‐end ports from System A and System B in a single zone. Storage Center SC8000 Controller Deployment Guide Connect the Front End for a Single-Controller Storage Center Connect the Front End for a Single-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. Connect Servers to a Single Controller with No Redundancy 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. Steps 1 Connect the FC fabrics. a Connect a controller FC port to each FC fabric. b Connect one or more FC servers to each FC fabric. c Configure FC zoning to meet the zoning requirements. If you are planning to configure FC in legacy mode, configure zoning to meet the legacy mode zoning requirements. If you are planning to configure FC in virtual port mode, configure zoning to meet the virtual port mode zoning requirements. 2 Connect the iSCSI networks. a Connect a controller iSCSI port to each iSCSI network. b Connect one or more iSCSI servers to each iSCSI network. 3 During the software setup process, configure fault domains based on the connectivity mode: Dell Compellent Legacy mode: Create one fault domain for each transport type (FC and iSCSI). Virtual port mode: Create one fault domain for each fabric or directly connected FC server. 103 Chapter 4 Connect the Front End FC Server SCSI Server FC Switch Ethernet Switch Controller Figure 90. Single Controller Without Front-End Redundancy See Also Fibre Channel Zoning on page 102 Connect Servers to a Single Controller with Redundancy Connect servers to a single controller using redundancy if you want to protect against port failure on the controller, switch, or server. In legacy mode, fault tolerance is provided by MPIO on the connected servers. In virtual port mode, fault tolerance can be provided by MPIO or controller port failover within each fault domain. Prerequisites The controller must have two available front‐end ports 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.
