I stand corrected. Most of the benchmarks I was referencing were for
dual 300MHz Intel SMP systems or better as dedicated fileservers. I
presume there are numerous servers out there that are not lucky enough
to only have to serve NFS shares and/or are using non SMP boards with
older/slower CPUs. If you want to offload the RAID processing from your
main CPU(s), hardware is definitely the way to go. I simply have yet to
see a benchmark for, say, a 5-drive U2 10Krpm RAID-0 that gets anywhere
near the sustained rates with a RAID controller as opposed to
software-level with a good multi-channel SCSI interface. Just my
half-nybble.
