So you have to remove the blade to get at the drives. Plus, the drives pump up the chassis power consumption as well. (Well, there is SCSI side-car option, but it eats up a blade slot.) So consolidating all storage on the SAN, make sense. Managing a bunch of 10GB boot LUNs is going to easier than dealing with 28 physical drives (2 per blade). I can put a pair of mirrored 146GB disks on the SAN, and slice out 10GB per blade. It is even a bit cheaper, including the SAN 64 partition licence. Tom
