NIC Adapters for VMware & NFS storage (NetApp)

For DELL R420 servers, do the Broadcom 5719 quad-port 1Gb NICs support NFS and are they as good as Intel I350 in terms of NFS performance?

I was able to find performance measurements for FCoE and iSCSI, but nothing for NFS.

Background Details
DELL R420
VMware ESXi 5.1 connecting via NFS to NetApp storage
(2) Intel Xeon E5-2450 2.10GHz, 20M Cache, 8.0GT/s QPI, Turbo, 8C, 95W
48 GB (1600 MHz)
LVL 8

I don't think you'll find a big difference between the controllers since it file access versus iscsi/fcoe where a controller may handle tcp offload.

NICs are NFS agnostic. They handle NFS as any other IP traffic. As long as you get a server grade NIC, and it's on the VMWare compatibility matrix,  you should be fine.

With Netapp I would recommend to create a separate IP for each datastore, if your ifgrp is setup for link aggregation this will allow you to create multiple sessions per ESXi host and improve throughput.  Since there is no MPIO with NFS this does a good job in distributing load.
