I've used LSI MegaRAIDs successfully in the following systems with both
Redhat 9 and FC3 64bit.
Arima HDAMA/8GB RAM
Tyan S2850/4GB RAM
Tyan S2881/4GB RAM
I've previously stayed away from Adaptec because we used to run Solaris
x86 and the driver was somewhat buggy. For Linux and FreeBSD, I'd be
less worried as open source development of drivers usually lead to
better testing & bug-fixing.
