Disk drive carriers are plastic assemblies that provide smooth, reliable contact with the
enclosure slot guides and midplane connectors. Each carrier has a handle with a latch and
spring clips. The latch holds the disk drive in place to ensure proper connection with the
midplane. The "Front view"
integrated into the chassis that the carrier is in. These LEDs primarily show the disk drive
readiness as well as activity.
You can visually distinguish between drive types by their different latch and handle
mechanisms and by the type, capacity, and speed labels on each drive. You can add or
remove a disk drive while the DPE is powered up, but you should exercise special care
when removing drives while they are in use. Disk drives are extremely sensitive electronic
components. For more information about the supported disk drives for the VNXe3100,

A midplane separates the front-facing disk drives from the rear-facing SPs. It distributes
power and signals to all components in the enclosure. SPs and disk drives plug directly
into the midplane.
The storage processor (SP) is the intelligent component of the disk processor enclosure
(DPE). Basically, it acts as the control center. Each SP includes status LEDs, an I/O
personality module, LAN ports, and so on. Two latches on the SP lock it into place to
ensure proper connection. The

When viewed from the rear, the power supply module is located on the top, left and right
of the DPE. This module is an auto-ranging, power-factor-corrected, multi-output, off-line
converter with its own line cord. Each power supply module includes status LEDs. A latch
on the power supply module locks it into place to ensure proper connection. The

In a single SP configuration, the Cache Protection Module provides mirrored VNXe
Operating Environment (OE) cache memory that is not possible with a single SP. The Cache
Protection Module capacity is 1 GB.
