The IBM Systems Storage 8000 and IBM ESS800 systems use an active-active array that does not need special configuration in conjunction with VMware ESXi.

The following considerations apply when you use these systems:

  • Automatic resignaturing is not supported for these systems.

  • To use RDMs successfully, a given LUN must be presented with the same LUN ID to every ESXi host in the cluster.

  • In the ESS800 Configuration Management tool, select Use same ID for LUN in source and target.

  • If you are configuring the host to use boot from SAN from these arrays, disable the internal fibre port for the corresponding blade until installation is finished.
