iSCSI
Each controller has a unique, permanent hardware address. Each controller host port
has a unique, user-defined IP address.
The following table shows example hardware addresses and port IP addresses.
SAS
Both controllers have the same unique, permanent node WWN. Each controller host
port has a unique port WWN that is based on the node WWN. The WWN format is:
5<OUI><serial-number><port-ID>00
■ OUI – The manufacturer’s unique identifier, 00C0FF.
■ serial-number – A serial number derived from the last six hex digits of the
midplane serial number.
■ port-ID – 0 for controller A port 0; 1 for A1; 2 for B0; 3 for B1.
The following table shows example node WWNs and port WWNs. Notice that the
node WWNs are the same and the port WWNs differ in the fourteenth digit.
