I use an Xserve RAID attached to a FreeBSD box (a Dell with Apple's
Fibre Channel card) to serve home directories via NFS to Solaris and
Linux machines. It works great, and I would consider buying another
Xserve RAID if I outgrow my current one. The FreeBSD kernel has a
driver for the card (the mpt driver, if I remember correctly) and the
RAID volumes show up as SCSI disks. The only problem I had was that
the FreeBSD installer gets confused with disks over 1 TB (I have two
1.1 TB volumes)
For a few months I had it attached to my Xserve G4 running Mac OS X
Server, but the machine was unstable (had several kernel panics) and
had some weird NFS issues on HFS+ disks. (Specifically, sometimes
certain files would refuse to be deleted. "rm filename" resulted in
"I/O error" .. but renaming the file and then removing it worked.
Wacky. This showed up particularly in directories with large numbers
of files which changed often, such as mail directories, but it also
often affected the .Xauthority file used by X11. Over time I also saw
filesystem corruption which fsck_hfs wouldn't fix.)
I haven't determined whether my Mac OS X Server problem was due to a
bad install or a configuration problem .. I needed a quick fix, and
the fasting thing to do was to just stick a BSD box in there as an NFS
server.. the Mac OS X Server box continues to do LDAP, SMB, AFP, etc.
