I am having issues run VMotion in my ESX 5.1 environment. Research I've been reading indicates I should have the VMotion network segregated. I have a dedicated physical NIC for VMotion, but it keeps timing out. I can create a new subnet and isolate it on its own switch between to the 2 hosts, but wouldn't the iSCSI SAN that hosts the VMs need access to this VMotion network as well? I am attempting to migrate the VM from 1 host to another, as well as change it from a datastore on an older SAN to a new one.
