Intel pro nics are good. But I prefer the adaptec nics. Not only does it do
failover but it does port aggregation. Where you could have their 4 port nic
card all with one ip address and the card doing load balancing to the
server. We use all of these on our database and web servers at work. We use
the 2 port nic cards for the file servers. Just my thoughts.

These cards do work under linux/unix but takes a bit of configuration to get
it to work.

If you use dual-port NICs you can configure them to have the same IP address
as a part of a Fault Tolerant Team (Intel Pro 100 dual-port NICs).
