Wh= at sort of hardware must one use to grow to a 36 array system! For the drives you could get a few big enclosures: http://www.pc-pitstop.com/sata_enclosures/sat122urd.asp http://www.pc-pitstop.com/sata_enclosures/scsas16rm.asp I don't think these offer PMP (port multiplexer) support. I would look for ones that did if you're serious about doing something like this. If you used PMP with 4x drives per sata port, you would only need 9 sata ports in the PC to control the 36 drives. Not sure what the limits of PMP is, but 4x seems reasonable to me.
