Rick, We just went through an exercise in purchasing new DASD for mainframe and *nix/windows. The price tag for adding FICON to the disk subsystems was ridiculous. This was on top of paying extra for the frames that even supported FICON as opposed to the ones that didn't. Everything else pretty much equivalent including the spindles spinning inside the cabinet.
We have had several "second tier" boxes over the years that have had reliability and uptimes right up there with what I expect out of a Z-box. Raid protected, redundant everything, and a lot lower price tag.

Stop and think, really hard, about the demands on z/OS DASD storage, as opposed to the "standards" you enjoy with your PC DASD. How many of your PC's stay up, with DASD spinning, on a 24/7 basis, for several years without problems?
