I am standing up a new file server and I need to connect it to my iSCSI SAN and I am looking for a good NIC to use for dedicated iSCSI with multi-pathing. What should I be looking for in a good dual-NIC card to dedicate to iSCSI?

Here is what I have so far in my list:

  • adjust MTU beyond defaults
  • hardware offloads for iSCSI tagged traffic
  • must be GigE

Are there things I should avoid?

The current way this is written, will probably mean that it will get closed as a shopping question. Try and re-word it so it is less subjective. Don't ask for a particular product. Ask something like what feature(s) are does a nic need to have for iSCSI to work well. Ask how to tell what NIC will be great for iSCSI. – Zoredache Nov 11 '11 at 22:24

I would never use Broadcom for anything without first reading this:

I have had some issues with Broadcom gear in the past, specifically in hyper-v machines on Dell hardware. The solution was to replace the Broadcom NICs with Intel. I'm looking to see if someone has a suggestion on a good NIC to use for iSCSI. – Top__Hat Nov 11 '11 at 22:28
