Please forgive the basic question, but I just want to be sure......

With regards to cluster IP address allocation , I'm assuming cluster IP
address, cluster pool IP addresses need to be on the same IP subent as the
NIC's connected to the SAN.

Do these NIC's exist on the same IP subnet as the network LAN or separate
and routed through the box? And therefore Is it possible using iSCSI to use
secondary IP addresses on single NIC's and connect them to the SAN and the
network LAN?
