HP MSA 2040 models support small form factor (SFF) and large form factor (LFF) enclosures. The SFF
chassis, configured with 24 2.5" SFF disks, is used as a controller enclosure. The LFF chassis, configured
with 12 3.5" LFF disks, is used as either a controller enclosure or a drive enclosure.
Supported drive enclosures, used for adding storage, are available in LFF or SFF chassis. The MSA 2040
6 Gb 3.5" 12-drive enclosure is the large form factor drive enclosure used for storage expansion. The HP
D2700 6 Gb enclosure, configured with 25 2.5" SFF disks, is the small form factor drive enclosure used for
storage expansion. See "SFF drive enclosure" (page 17) for a description of the D2700.
