We have Dell Poweredge 2950, R510, and R710 servers. We want to use separate NICS for the iSCSI traffic to the servers than the LAN traffic. We need 2 of each (LAN and iSCSI) for HA.
I think the 2950 and R710 have 4 onboard NICs and the R510 has 2.
I've heard of iSCSI HBA's, regular gigabit NICs and then recently something about a TOE NIC which is kind of half way.
Any recommendations for which cards to buy? or if I should just use onboard NICs when possible? We don't anticipate booting from SAN but our CPU % utilization is above 70% quite often.
