• For 4U enclosures, insert two Torx M5 (long) screws into the mounting holes on each side

This section provides information about the requirements and installation order for disk drives in

SFF and LFF drive enclosures.

Only 2.5-inch drives can be installed in HP 3PAR 7200/7400 controller node enclosures and HP

M6710 (2U) drive enclosures. The 3.5-inch drives can be installed only in 4U M6720 drive

enclosures.
