What exactly are you trying to do? Do you need a clustered filesystem
or just a bunch more disk IO per server? The best bang for your buck
as far as getting a ton of disk spindles is coraid san's using AoE.
http://coraid.com/pdfs/datasheets/EtherDriveSR2461.pdf
We use tons of these systems with high performance disks as well as
off the shelf 400gig SATA commodity drives. The Xen domU's see a
direct block device exported from the dom0 that talks to the coraid
over AoE.
