So I'm setting up a new ESXi 4.1 Update 1 system that involves two hosts, each with a Broadcom 5709 Hardware Dependant adapter containing two NICs, and a centralized iSCSI SAN. I've followed the "iSCSI SAN Configuration Guide ESXi 4.1" and configured each NIC on the broadcom card on it's own separate switch. From reading the guide, this is supposedly neccessary:
If your host has more than one physical NIC for iSCSI, for each physical NIC, create a separate iSCSI port using
To achieve the 1:1 mapping, designate a separate vSwitch for each network adapter and iSCSI port pair. See
If you look on page 38 at Figure 2-2, you'll see that each NIC is now configured to its own vSwitch.
While it seems a little over the top to have one switch per iSCSI adapter, I wouldn't care if I could figure out how to team/bond or achieve multipathing afterwards. I can't seem to get more than one connection per host to my SAN with this setup, so I'd like some guidance on that.
I'm eventually going to have a total of four 5709 NICs on each host, and I'd like to dedicate one for vMotion, one for HA, and the other two in a bonded/teamed configuration for my VM management traffic.
Can anyone provide some suggestions or steer me in the right direction?
