In the static route page, the IP address I have to enter is the DSS IP or the ESXi iSCSI IP? I tried both but DSS said it's invalid.

btw, if I were to use a difference subnet for every interface, does this mean that I need to create 4 VLAN on my switch too? Does this also mean that I will not get to enjoy failover since I only have 1 interface at every subnet?
