EMC® VNX5300™ Hardware Information Guide
Midplane
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.
Storage processor (SP)
The SP is the intelligent component of the disk processor enclosure (DPE). Basically, it
acts as the control center. Each SP includes status LEDs, PCI Gen 2 x4 I/O module
slots, LAN ports, and so on. For detailed information, go to
Storage processor (SP) power supply
The SP power supply is located on the top, left side of the SP when viewed from the
rear. This module is an auto-ranging, power-factor-corrected, multi-output, off-line
converter with its own line cord. Each power supply includes status LEDs. A latch on
the power supply locks it into place to ensure proper connection. For detailed
information, go to
“SP AC power supply” on page 23
.
EMI shielding
EMI compliance requires a properly installed electromagnetic interference (EMI)
shield in front of the DPE disk 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. You must remove the bezel/shield
to remove and install disk drive modules.
3U, 15 DPE front view
On the front, the Block and File VNX5300 platform 3U, 15 (3.5-inch) DPE carrier
includes the following:
◆
3.5-inch 6-Gb/s SAS or 6-Gb/s NL-SAS disk drives (hot-swappable)
5
◆
Status LEDs
shows the location of these disk drives and Status LEDs.
5. You can add or remove a disk drive while the DPE is powered up, but you should exercise
special care when removing disk drives while they are in use. Drive modules are extremely
sensitive electronic components.
