Got a quick question. I have a FAS3140 with 4 DS14MK2 AT disk shelves attached to it in an FCAL loop. The shelves have 1TB SATA disks. We're thinking of adding a SAS add-on card and a DS4243 disk shelf to it with 24 x 1TB SATA disks. Question is, will I be able to add the disks on the DS4243 to my already existing aggregates on the DS14MK2 shelves, or will I have to create new aggregates on the DS4243. In other words, can an aggregate be composed of same capacity disks from different disk shelf types (DS14MK2 AT & DS4243)?
