failover for the encryption path between the host and target in fabric 1. Encryption switches 2 and
4 act as a high availability cluster in fabric 2, providing automatic failover for the encryption path
between the host and target in fabric 2. All four encryption switches provide an encryption path to
the same LUN, and use the same DEK for that LUN, forming a DEK cluster.
