My numbers from sgi origin2000 to sgi origin2000, with no router hops, came through at around 3Mbyte/sec over 100Mbit network and nfs. This was a for a transfer of a single 1GByte file.
Interested in filer specs when communicating with origins, and also with gigabit ethernet hardware (presumably the origins can deal with the overhead?).

I'm evaluating a NAS filer similar to the ones sold by NetApp and Auspex. This particular model is made by Nitech in Irvine, CA. These NFS vendors speak about benchmarks in ops/sec. It's more intuitive for me to think of benchmarks in terms of MB/sec throughputs for a large file write or read.
My quick-and-dirty tests show that I can write at 1.8 MByte/sec over a 100Mbit network using NFS v3. I can FTP at about 7 MByte/sec.
My question is: do these numbers seem reasonable? If not, what aspects of NFS should I tweak?

p.s. methods:
to make a 100MB file: dd if=/dev/zero of=/tmp/bigfile bs=1024 count=102400
time cp /tmp/bigfile /home/bigfile
(where /home is the NFS server).
