MD3200i Series Storage Array
The Dell PowerVault MD3200i 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 MD3200i 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 system. Connectivity between the storage array and the host
server is provided by a standard Ethernet connection.
Dell PowerVault Modular Disk Stor ag e Man ager
Dell PowerVault Modular Disk Storage Manager (MDSM) is a graphical user
interface (GUI) application, used to configure and manage one or more
MD3200i Series Storage Arrays. The MDSM software is located on the
MD3200i Series resource media.
Dell PowerVault Modular Disk Configuration Utility
Dell PowerVault Modular Disk Configuration Utility (MDCU) is an iSCSI
configuration wizard that can be used in conjunction with MDSM to simplify
the configuration of iSCSI connections. The MDCU software is located on
the MD3200i Series resource media.

expansion enclosures are daisy chained to the
storage array, the enclosure mode switches of the
MD1200 Series expansion enclosures must be set
to the Unified-Mode position.
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 MD3200i 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 225.
CAUTION: A power supply/cooling fan module can be removed from a powered-
on system for a maximum period of 5 minutes. Beyond tha t time, the system may
automatically shut down to prevent damage.
