Drives and indicators

Drives are accessible from the front of the control enclosure. Each drive on a control expansion has two light-emitting diode (LED) indicators; they have no controls or connectors.

Control enclosures can house 24 2.5 in NVMe Flash Drives. Figure 1 shows a SFF 2.5 in. (6.35 cm) drive with the latching mechanism open.
