Does any other BSD (or Linux) support ServeRAID? Is proper

documentation is available.
There is a Linux driver, present at least in SLES 10 and some RHEL,
and IBM provides it originally, and you can find updates on IBM's web
I seem to remember that someone posted an initial stab at a driver quite a
while ago now.
IBM themselves use Linux to do the automated installed (ServerGuide).
I happen to have done raw performance tests the past week because of a
project at work involving that very system, and I can't say I'm
impressed with the speed, at least with SATA disks.
The S-ATA RAID1 performance on (e.g.) x3250 sucks (even under Windows).
The full on ServeRAID RAID-5 with 15k SAS disks is a different matter...
