If you're going with Promise consider an enclosure.  The UltraTrak100TX4
and 100TX8 both act like standard hardware RAID arrays, hot swap + hot
spare, but appear to the system as an Ultra2 LVD-SE SCSI device.  With
the Symbios cards we use (kernel patch supplied by Symbios as source --
LSI Logic is a TERRIFIC company to work with) we have not had any
problems and throughput has been exceptional.

Promise makes good cheap hardware, but I prefer a more specialized
vendor for my SCSI controllers, especially with the torture I put our
systems through.  (how many other people do you know running RAIDframe
on OpenBSD for example -- LSI/Symbios even attempts to help with THAT!)
