ok. now that is a pretty impressive goal.

yow. well, i wonder if you will get 100Mbyte/sec performance with the
hardware you outlined.

hmm, i guess you will definitely want to test if the hardware raid on the
2650 will deliver that (either the onboard perc4/di, or the extra perc3/QC
card). otherwise you're looking at software raid. some other admins here
have quoted figures of around the 60-80Mbyte/sec range for their software
raid setups but i can't remember if they're past 100 for reads. perhaps
it's time to head to the mail archives batman..

have a look around www.netapp.com as there are some links there to white
papers on NFS and also some specNFS type pointers.
i, and quite a few others would be very interested in your results at that
