2U, 25-drive DPE component overview

The 25-drive DPE is two rack units (U), 8.9 cm (3.5 in.) high, 79.2 cm (31.2 in.) deep,

and includes slots for twenty-five 2.5-in. drives.

The DPE consists of the following components:

lDrives

lMidplane

lStorage processor assembly

lPower supply module

lEMI shielding

Drives

Each drive consists of one drive in a carrier. The drive carriers are metal and 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 drive in place to ensure proper connection with the midplane. Drive activity

and fault LEDs are located on the front of the enclosure.

SAS and SAS flash drives are supported. The drives are populated in the system from

left to right.

Note

The first four drive slots are reserved for system drives, and should not be removed.

You can visually distinguish between drive types by their different latch and handle

mechanisms and by type, capacity, and speed labels on each drive. You can add or

remove a drive while the DPE is powered on, but you should exercise special care

when removing modules while they are in use. Drives are sensitive electronic

components.

Midplane

The midplane separates the front-facing drives from the rear-facing SP assemblies. It

distributes power and signals to all components in the enclosure. The SP assemblies

and drives plug directly into the midplane.

Storage processor assembly

Each DPE contains two SP assemblies. The SP assembly is the intelligent component

providing the compute capability of the DPE. Acting as the control center, each SP

assembly includes status LEDs.

Storage processor assembly power supply module

Each SP assembly contains a power supply module that connects the system to an

exterior power source. Redundant power supplies can keep the entire DPE running if

one power supply fails. The power supplies include LEDs to indicate component status.

A latch on the module locks it into place to ensure proper connection.

EMI shielding

EMI compliance requires a properly installed electromagnetic interference (EMI)

shield in front of the DPE drives. When installed in cabinets that include a front door,

the DPE includes a simple EMI shield. Other installations require a front bezel that has

a locking latch and integrated EMI shield. Remove the bezel or shield to remove and

install the drives.

System identification tags

The Product Serial Number Tag (PSNT) and World Wide Name Seed are serialized

labels that allow customer support to track nested hardware material in the field.

Product Serial Number Tag

The PSNT for the 25-slot DPE is a black pull-out tag that is located between the

drives in slots 16 and 17.

World Wide Name (WWN) Seed Tag

The World Wide Name (WWN) Seed tag is a blue pull-out tag that is located between

the drives in slot 7 and 8.
