I have several servers that we are about to deploy Oracle RAC to. Each of these servers have 6 NICs. We would like to take 4 of the NICs and dedicate them to the RAC interconnect in bounded pairs. I would like to bound 2 NICs (for ~200MB of throughput) and connect them to 6509E and configured the other 2 NICs and connect them to another 6509E for failover purposes.
I would suspect that I would use LACP on the switch side, but what would I need to do on the server side? Im using Broadcom NICs, and was hoping to use a kernel mode driver (vs. the Broadcom software). Is this a common practice?
Also, are there any switch configuration settings for tweaking performance (other than jumbo frame support)?
