RE: Intel (e1000) vs Broadcom (tg3) NICs for Oracle RAC

We have seen a number of issues with high-throughput situations with broadcom nics where under very heavy IO loads the card becomes unresponsive. However, we only create this situation in our vmware environments where we run a lot of iSCSI and NFS and RAC, and I've never seen a problem with the broadcoms in regular IO environments.

But, just to be safe we typically encourage customers running RAC to pick up some extra e1000 ports if the servers ship with broadcom onboard.

Thanks,
Matt

both are reliable on the hardware side. i use both and never had an 
issue with the hardware.

but i had some trouble with e1000 and redhat el5. the driver shipped 
with rhel5 did not work with my e1000. switching to intel's driver 
solved the problem.
