IBM blades do not have hotswappable drives on the blades. 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.
