Connecting devices in a MetroCluster configuration with array LUNs

You should plan the cabling required for your MetroCluster configuration before you start connecting the devices. It is helpful to have a port-to-port connectivity diagram to use for reference while you are connecting the devices in a MetroCluster configuration with array LUNs.

About this task

The following example illustration shows the connections between devices in a MetroCluster configuration that uses array LUNs.

This graphic depicts an example MetroCluster configuration with array LUNs. The graphic is described by the surrounding text.

Steps

  1. Connect the FC-VI ports a and b from each controller to the alternate FC switch.
    Perform the controller-to-switch connections at both Site A and Site B.
    The following table lists the connections between the FC-VI ports and the FC switches for the configuration shown in the example MetroCluster illustration:
    FC-VI Ports FC Switch Ports
    Site A:
    Controller A1: FC-VI Port a Switch A1, Port 2
    Controller A1: FC-VI Port b Switch A2, Port 5
    Controller A2: FC-VI Port a Switch A1, Port 4
    Controller A2: FC-VI Port b Switch A2, Port 4
    Site B:
    Controller B1: FC-VI Port a Switch B1, Port 2
    Controller B1: FC-VI Port b Switch B2, Port 5
    Controller B2: FC-VI Port a Switch B1, Port 4
    Controller B2: FC-VI Port b Switch B2, Port 4
  2. Form ISL connections from each FC switch at Site A to a corresponding switch at Site B.
    In the example MetroCluster configuration, FC switch A1 at Site A is connected to FC switch B1 at Site B to form a switch fabric. Similarly, switches A2 and B2 form another switch fabric.
  3. Connect the FC initiator ports from each controller to the FC switches.
    For every controller at a site, ensure that at least two initiator ports are connected to the corresponding switch and the other two ports are connected to the alternate switch.
    The following table lists the interconnections between the FC initiator ports and the switches in the example MetroCluster configuration:
    FC Initiator Ports FC Switch Ports
    Site A:
    Controller A1: Port 0a Switch A1, Port 1
    Controller A1: Port 0b Switch A2, Port 2
    Controller A1: Port 0c Switch A1, Port 3
    Controller A1: Port 0d Switch A2, Port 3
    Controller A2: Port 0a Switch A1: Port 5
    Controller A2: Port 0b Switch A2, Port 1
    Controller A2: Port 0c Switch A1, Port 6
    Controller A2: Port 0d Switch A2, Port 6
    Site B:
    Controller B1: Port 0a Switch B1, Port 1
    Controller B1: Port 0b Switch B2, Port 2
    Controller B1: Port 0c Switch B1, Port 3
    Controller B1: Port 0d Switch B2, Port 3
    Controller B2: Port 0a Switch B1, Port 5
    Controller B2: Port 0b Switch B2, Port 1
    Controller B2: Port 0c Switch B1, Port 6
    Controller B2: Port 0d Switch B2, Port 6
  4. Connect the ports of the storage arrays to the FC switch ports.
    Perform the storage array-to-switch connections at Site A and Site B.
    The following table lists the connections between the storage array ports and the FC switches for the example MetroCluster configuration:
    Storage Array Ports FC Switch Ports
    Site A:
    Storage array 1: Port 1A Switch A1, Port 7
    Storage array 1: Port 1B Switch A1, Port 8
    Storage array 1: Port 1C Switch A1, Port 9
    Storage array 1: Port 1D Switch A1, Port 10
    Storage array 1: Port 2A Switch A2, Port 11
    Storage array 1: Port 2B Switch A2, Port 10
    Storage array 1: Port 2C Switch A2, Port 9
    Storage array 1: Port 2D Switch A2, Port 8
    Site B:
    Storage array 2: Port 1A' Switch B1, Port 7
    Storage array 2: Port 1B' Switch B1, Port 8
    Storage array 2: Port 1C' Switch B1, Port 9
    Storage array 2: Port 1D' Switch B1, Port 10
    Storage array 2: Port 2A' Switch B2, Port 11
    Storage array 2: Port 2B' Switch B2, Port 10
    Storage array 2: Port 2C' Switch B2, Port 9
    Storage array 2: Port 2D' Switch B2, Port 8
  5. Configure the switch zoning according to the zone plan.
