Requirements for a shared-switches MetroCluster configuration with array LUNs

There are specific requirements for creating a shared-switches MetroCluster configuration with array LUNs.

You need the following to create a shared-switches MetroCluster configuration with array LUNs:

  • In releases prior to Data ONTAP 8.2, four Brocade 5100 switches. In Data ONTAP 8.2 and later, four Brocade 5100 switches or 6510 switches.
  • Two storage arrays at each site.

    One storage array at one site is used for the first MetroCluster configuration and the other storage array at the site is used for the second MetroCluster configuration.

    Note: A single storage array at each site is supported if the target ports on the storage array and the array LUNs are not shared between the two MetroCluster configurations.
  • A minimum of two ISLs per fabric with TI enabled.
