Do you plan on massive future scalability? A full Bladecenter will give you marginally more CPUs per U of space than (I think) any ordinary xSeries. If you're buying lots of gigahertz, that will be a big factor. Using Bladecenter bays for SCSI storage is going to cut into that. Personally, if I were standing here with a blank check in my hand, I'd get Blades and EXT units rather than waste chassis space on SCSI Blades. Bear in mind that a Blade is basically a laptop. Servicability isn't something you can expect. Generally, people who have one of their Blades go bad get a warranty replacement on the whole thing rather than on any FRU inside it. OTOH, I've been inside the x345, and it's a pleasure to expand and to work on. Is this for a Small/Home business or an Enterprise? Maintenance is less on Blades, since you're paying for a quick yank and replace, as opposed to a full service on a machine, but those savings only become apparent if you're buying a lot of them, and working them hard.
