This won't help your system disk situation, but I've been playing with iSCSI
on linux.  It looks like a good way to add data space to your file server.

Use an old PC, put 4 disks and a gigabit card in, install a minmal linux
with iSCSI target and software RAID of the 4 disks in, put a gigabit card,
crossover cable and iSCSI initiator in your server and mount the target.
Looks like regular disk you can partition, LVM and share out on the server.

Free iSCSI targets exist for Linux and Solaris 10 u1.  Initiators exist for
Linux, Solaris 10u1, Windows.

FWIW, dd if=/dev/zero of=disk bs=8192 count=1000 was about 30% slower over
iSCSI (single disk) on 100T then local RAID1 disk.  With those numbers,
gigabit should be faster.
