Hi -
Mostly by accident, I just noticed that I can essentially max out my 720 over 100bT on writes. I did this a few times with mostly the same results. This is a production environment, but at an idle period. Notes on sysstat output, below: I first copied it back to the Sun box, and then copied it from there to the 720 again. Reads were a bit high, but within the realm of acceptable; writes were... intense. It is pretty clear in the output where the read stopped and the write started, modulo the averaging.
Is this normal for a 720? I don't forsee 5 saturated 100Bt connections in the near future, but... this does make me wonder about scaling.
Thanks for any thoughts.
