Is the backplane of a Dell PowerVault 220S svc tag 3sdpcb1 (14 drive, 80 pin hot swap scsi) upgradeable to a SAS/SATA backplane & controller card replacement?
The unit already seems to be quite modular, with slide-out replaceable scsi controllers/connectors on the back, and slide out redundant power supplies.
With everything else so modular, the backplane would seem to be the next logically upgradeable part of this unit.
