Best 10G Ethernet NIC for R815?

I have placed Myricom 10G cards in the latest AMD platforms (magny cours) and have been doing netperf tests over 900Gb/s. To do that I had to enable jumbo frames and use the driver from Myricom rather than the one that comes with the Redhat 5.x kernel.

This has been on supermicro based machines and not the Dell R815 so YMMV, but I have been happy with the performance and the boxes should be more or less the same (quad socket 6100)

Hi all,

does anyone have experience what the best 10 Gb/s SFP+ NIC (in terms of
throughput) for the R815 is? The affordable Intel NICs all rely on techniques
for high-performance such as QuickData etc. that require Intel chip-sets and
CPUs and are simply not available on the AMD platform.

Any hints are appreciated!
