In the physical machine we have 6 NICs:
0&1 are 1gb NICs on a vSwitch0 with vmKernel port configured for Management
2&3 are 1gb NICs on a vSwitch1 with Vmkernel port configured for vMotion and IP Storage Port
4&5 are 10gbe NICs on a dvSwitch configured for virtual machine traffic on multiple vLANs.
I thought that the iSCSI traffic would be controlled by the vmKernel ports configured for IP Storge as the vSwitch1 but that after discovery the actual IO would be traveling over the dvSwitch on NICs 4&5. But now I am starting to question that. Is the iScsi traffic going over that IP Storage Port (i.e. 1gb NIC) or over the dvSwitch where the virtual machine traffic is (10gbe)?
