MD3200 Series Storage Array

The Dell PowerVault MD3200 Series is a 2U rack-mounted external redundant array of independent disks (RAID) storage array capable of accommodating up to twelve 3.5" or twenty four 2.5" 6.0-Gbps SerialAttached SCSI (SAS) disks. The MD3200 Series storage arrays can be daisychained with MD1200 Series expansion enclosures, providing access to a maximum of 120 disks (or 192 disks with Premium Feature activation) in the entire storage array. Connectivity between the storage array and the host server is provided by a Dell 6.0-Gbps SAS Host Bus Adapter (SAS 6Gb HBA).

Planning: About Your Storage Array

Overview

The MD3200 Series storage array is designed for high availability, offering redundant access to data storage. It features support for both single and dual RAID controller configuration.

The Dell PowerVault MD3200 Series storage array provides 6.0-Gbps SAS connectivity to the host server and enables access for up to eight nonredundant servers or four redundant servers.

The MD3200 Series storage array includes a number of components. These are:

• RAID controller module(s)

•PSU/Fan modules

• Disk drives (also called physical disk drives in this document)

• A front bezel (optional)

• A system enclosure, into which, the other components are plugged

NOTE: This switch must be set before turning on

the MD1200 Series expansion enclosure. Changing the switch setting after the expansion enclosure is turned on has no effect on the enclosure configuration until the expansion enclosure goes through a complete power cycle.

Power Supply and Cooling Fan Features

The MD3200 Series storage array includes two integrated, hot-swappable power supply/cooling fan modules. Both modules must be installed to ensure proper cooling. The system requires at least one of the cooling fans to function to avoid overheating.

A power supply/cooling fan module can be replaced without powering down the system. For information on removing and installing the modules, see "Power Supply/Cooling Fan Module" on page 216.

CAUTION: A power supply/cooling fan module can be removed from a powered-

on enclosure for a maximum period of 5 minutes. Beyond that time, the system may automatically shut down to prevent damage.
