I have a moderately aged Tyan S4882 system that I need to support 12 SATA disks with for a ZFS pool. The motherboard doesn't provide any PCI-Express slots, but does have two 133 MHz PCI-X slots. Other than a 3ware S9550SX-12 or Areca ARC-1130, both of which are a bit hard to find, I was wondering if anybody had suggestions for me.
