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.
