Maximum drives	750	1000	1500
Minimum drives	6	6	6
Array enclosure	A 2U Disk Processor Enclosure (DPE) with twenty five 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

Drive counts listed in parentheses next to the maximum amount of DAEs represent the maximum achievable drive count when using the maximum of each DAE, plus the 25 drives on the DPE.

Embedded module specifications

Supported optional 4-port cards:

10GbE BaseT 4-port card
25GbE 4-port card

The 4-port card can also be left unpopulated.
