Connecting to Host Servers with iSCSI HBAs or 

Network Adapters

A storage system with iSCSI front-end ports connects to one or more Ethernet switches, which connect to one or more host servers with 
iSCSI HBAs or network adapters.

Cable the Storage System with 2–Port iSCSI IO Cards

Connect the iSCSI ports on the storage controllers to host servers with iSCSI HBAs. The iSCSI ports of the storage controllers connect to 
the host servers through the Ethernet switches in the SAN.

Steps

Connect each host server to both iSCSI networks.

Connect fault domain 1 (shown in orange) to iSCSI network 1.

Connect port 1 of the iSCSI HBA in the top storage controller to switch 1.

Connect port 1 of the iSCSI HBA in the bottom storage controller to switch 1.

Connect iSCSI fault domain 2 (shown in blue) to iSCSI network 2.

Connect port 2 of the iSCSI HBA in the top storage controller to switch 2.

Connect port 2 of the iSCSI HBA in the bottom storage controller to switch 2.
