About the Deskside Disk-Array Processor Enclosure
The disk module slots in the enclosure accommodate drives with
heights of either 2.54 cm (1.0 inch) or 4.06 cm (1.6 inches). You can
combine drives of either height, and from different manufacturers,
within the same deskside DPE, subject to the restrictions imposed by
the Licensed Internal Code (LIC) running in the DPE’s SPs.
Drive Carrier
The disk drive carrier is a plastic assembly that provides smooth,
reliable contact with the enclosure slot guides and the midplane
connectors. It has a handle with a latch and electrostatic discharge
(ESD) clips, which connect to the drive’s head-disk assembly. The
latch holds the disk module in place to ensure proper connection with
the midplane.
Link Control Cards
(LCCs)
The deskside DPE includes two types of LCCs: one type for the DAE
enclosure and another type for the DPE enclosure. LCCs in the DAE
enclosure have a primary connector and an expansion connector.
LCCs in the DPE enclosure have only an expansion connector. The
figure below illustrates both types of LCC.
