I see. I'll try to get my hands on one, but anything that's hard to buy is also not an option (as always with universities, there is already enough bureaucracy involved). Unfortunately, this limits the choice of hardware :-( > My only complaint on FreeBSD 9.X so far is that, > it has trouble doing SMART probes on the disks using passthrough :) Uh, that's bad with that many disks...

Unfortunately, the mainboard doesn't have any PCIe slots, because then I assume I would have a lot more cards to choose from... Best regards, Moritz
