I have the main filesystem on 10k SATA drives in a RAID1 array with /home accessed via NFS from another machine residing on 7k SATA drives in a RAID 10 array. Seems to work pretty well, the bottleneck seems to be the processors now. That's with 70 clients, but only maybe 20 - 30 in use at the same time. -Steve ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
