The only decent ones that I know are from 3ware and areca. I have no
experience with the areca cards (I'll be getting a few in the next weeks
though) but both have drivers are in RHEL4/5.

There are some problems with the 3ware cards and performance under
certain loads so you might want to test it first. Here is a more or
less random collection of links about the cards problems.
