> IBM sells some nice one rack units as well. speaking of. anyone have any experience with the IBM DS3500 storage? I've been considering the DS3500 for my dev lab storage. These come 24x2.5" (or 12x3.5") SAS 2U boxes with redundant storage controllers that have 2x2 SAS host ports and either 2x4 gigE iscsi or 2x4gb FC ports. you get to pay extra for more host partitions and stuff. they are basically rebranded LSI/Engenio 2600 and come in both 12x3.5" or 24x2.5" 2U SAS chassis... there's also SAS expansion ports you can add several additional storage bays to. I have zero (0) experience with IBM branded storage. I do have a IBM Bladecenter and Power 520 AIX server in my lab, so I'm not all together unfamiliar with IBM.
