Hardware Information Guide
REV A03
October, 2011
This guide describes one of five models available in the VNX Series, the EMC
VNX7500™. This document provides an overview of the architecture, components, and
features of the VNX7500. The specific aspects of the Block and File (Unified) VNX7500
platform hardware and its major components include the front and rear connectors and
LED indicators on the storage processor enclosure (SPE), the 1U and 2U standby power
supply (SPS), the Control Station, the Data Mover enclosure, and the 2U, 25 (2.5-inch), the
3U, 15 (3.5-inch), or the 4U, 60 (2.5-inch or 3.5-inch) disk drive disk-array enclosure
(DAE).

    Disk-array enclosure (DAE) Disk-array enclosure (DAE) Lifting the DAE and installing it to or removing it from a rack is a two-person job. If needed, use an appropriate lifting device. A fully loaded 2U DAE, 3U DAE, or 4U DAE weighs approximately 45 lb (20.41 kg), 68 lb (30.84 kg), or 213 lb (96.62 kg), respectively.
  • Page 62 Disk-array enclosure (DAE) Drive carrier The disk 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 disk drive in place to ensure proper connection with the midplane.
  • Page 63 Disk-array enclosure (DAE) Power supply In a 2U or 3U DAE, the power supply/cooling module integrates independent power supply and blower cooling assemblies into a single module. Each power supply is an auto-ranging power-factor-corrected, multi-output, off-line converter with its own line cord. The drives and LCC have individual soft-start switches that protect the disk drives and LCC if you install them while the disk enclosure is powered up.
