Connections

Ensure that you are familiar with the specific connection types for the SAN Volume Controller and the uninterruptible power supply.

Each SAN Volume Controller node requires the following connections:

  • Each SAN Volume Controller node requires one Ethernet cable to connect it to an Ethernet switch or hub. The cable must be connected to port 1. A 10/100/1000 Mb Ethernet connection is required for each cable. Both Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) are supported.
    Note: For increased redundancy, an optional second Ethernet connection is supported for each SAN Volume Controller node. This cable is connected to Ethernet port 2.
  • To ensure system failover operations, Ethernet port 1 on all nodes must be connected to the same set of subnets. If used, Ethernet port 2 on all nodes must also be connected to the same set of subnets. However, the subnets for Ethernet port 1 do not have to be the same as Ethernet port 2.
  • Each SAN Volume Controller node has four Fibre Channel ports, each of which is supplied with an LC-style optical small form-factor pluggable (SFP) transceiver that is a gigabit interface converter (GBIC) for connecting to a Fibre Channel over Ethernet (FCoE) switch.
  • Each SAN Volume Controller node has two FCoE ports, each of which is supplied with an LC-style optical small form-factor pluggable (SFP) transceiver for connecting to a Fibre Channel over Ethernet switch.
    • The SAN Volume Controller 2145-DH8 supports the 10 Gbps Ethernet adapter, with four FCoE ports.
  • Each SAN Volume Controller node requires connections to the host systems. This connection might be:
    • Fibre Channel connections through the four Fibre Channel ports per node
    • Two FCoE ports per node or iSCSI connections through the two 1 Gbps Ethernet ports per node
    • If the 10 Gbps Ethernet adapter is installed, connection through the two 10 Gbps Ethernet ports per node
  • Fibre Channel ports and FCoE ports connect nodes in the SAN Volume Controller system.

Each uninterruptible power supply requires a serial cable that connects the uninterruptible power supply to the SAN Volume Controller node. Ensure that for each node, the serial, and power cables come from the same uninterruptible power supply.

Note: There is no uninterruptible power supply with the SAN Volume Controller 2145-DH8.
