I have to disagree with that. We routinely run multiple (up to six, and the only reason it's only six is we don't have any more to test so perhaps more will run) LTO4 drives as fast as they want to run using and IBM x3850 processor. We run four at a time using an x3650. The buses are PCI-E, drives are either SAS or FC. Would that box run six or eight of the IBM fancy pants drives? I don't know, haven't ever seen it tried.
For most sites, Windows and the crummy little hardware it runs on will be just fine. For you big fellas, not so much. If you are in the "gotta push 3-6TB/day" Windows will work. For you 10TB/day folks, maybe not.

It boils down to Wanda's statement: "I/O, I/O, it's all about I/O" --- Wanda Prather If you can do the work with LTO-1 or -2 drives, or DLT-7000, or similar speed/capacity, then Windows will work. When you get into high-speed/high-capacity drives the Intel/AMD architecture comes unglued. A single LTO-4 drive will use ALL the I/O bandwith of a PCI or PCI-x bus, and a significant chunk of a PCIe(1) bus. The challenge becomes one of finding a suitable X86 server with multiple PCIe busses in the design. IBM has the GX series I/O modules with two PCIe busses each for the P6 architecture that allows for significant I/O bandwith expansion -- for a cost, of course.

Somebody is listening. I had this discussion with one of our customers yesterday. It really does/should boil down to the OS experience you have on hand. Does the AIX platform have more capacity/performance than the best Windows platform? I'm guessing it probably does. But at what cost? And then more importantly: do either of the platforms have enough for you? If both do, then pick the one that makes more sense based on your OS experience. And remember: one can always divide and conquer.
