A quick back of the napkin estimate guesstimates that this 3ware stuff would max at 6 racks of disks on NUMA-Q or 3/8 of a rack per node (ignoring cabling, which looks infeasible, but never mind that), which is a smaller capacity than I remember FC having. NUMA-Q's a bit optimistic for 3ware because it has buttloads of PCI slots in comparison to more modern machines.
