Actually Mark..I just did an HP DL320 (the system I believe you were talking about) with 9TB (12x750 SATA) for a client for under $8K. This include $400 or so for three years of on site services, before requesting any additional (special) discount. So your $11K estimate is more than a bit high.

We are going to buy a small size beowulf cluster with 32 multicore processors (INTEL or AMD multicore processor). does "multi" mean 2 or 4 to you? also, are you talking dual-socket or single (or quad)? We don't care the network, but we need a big storage disks. that's even more poorly defin
