Array Enclosure:
2U Disk Processor Enclosure (DPE) with 25 2.5” drives

Drive Enclosure (DAE - Disk Array Enclosure):
All-Flash (F) models support 2.5” drives in 2U twenty five drive and 3U eighty drive trays. Hybrid models support 2.5“ drives in 2U twenty five drive and 3U eighty drive trays; and 3.5” drives in 3U fifteen drive trays.

Standby Power System:
Dell EMC Unity systems are powered by 2 power supplies (PS) per DPE/DAE. Each power supply can provide power to the entire module if the peer PS has been removed or is faulted. DPE power during a power failure is provided by a Battery Back Up (BBU) module. BBU is located within the SP enclosure and provides power to a single module (power zone)
