PowerEdge 2900 server (dual Xeon 5160 CPU's) and it seems to be pretty
maxed out with two tape drives. On my R710 I only get 70MB/sec despool
rates to LTO-4 drives.
If you can't get higher results when using a SAN I'd thin

Hi everyone,
Our setup consists of a Dell 2950 server (PERC6i) w/ FreeBSD7 and two HP
