Use IP routing to segregate Storage network
Hi Astro - This is simple, when you define the LUN in the iSCSI Client software, connect to the SAN provider's IP address on the storage network. In your example, if you setup the iSCSI client to use the iSCSI Target by IP address on the 10.251.1.0/24 network, and if both client and server have NICs on the 10.251.1.0/24 network, iSCSI traffic will automatically stay on that network due to IP routing.
