Introduction
This guide provides information about deploying Dell PowerVault MD3200
and Dell PowerVault MD3220 storage arrays. The deployment process
includes:
• Hardware installation
• Modular Disk Storage Manager (MDSM) software installation
• Initial system configuration
Other information includes system requirements, storage array organization,
and utilities.
NOTE: For more information on product documentation, see
dell.com/support/manuals.
MDSM enables an administrator to configure and monitor storage arrays for
optimum usability. The version of MDSM included on the PowerVault MD
series resource media can be used to manage both the PowerVault MD3200
series and the earlier PowerVault MD series storage arrays. MDSM is
compatible with both Microsoft Windows and Linux operating systems.
System Requirements
Before installing and configuring the PowerVault MD3200 series hardware
and software, ensure that a supported operating system is installed and the
minimum system requirements are met. For more information, see the
Support Matrix at dell.com/support/manuals.
Management Station Requirements
A management station uses MDSM to configure and manage storage arrays
across the network. A management station must meet the following
minimum system requirements:
• Intel Pentium or an equivalent processor (1333 MHz or faster) with 512
MB RAM (1024 MB recommended).
• 1 GB disk space.

8Introduction
• Display resolution of 1024x768 with 16 million colors (1280x1024 32-bit
recommended).
• Microsoft Windows, Red Hat Enterprise Linux, or SUSE Linux Enterprise
Server.
NOTE: Supported operating systems include both native and guest operating
systems.
NOTE: Supported hypervisors include Microsoft Hyper-V, Citrix XenServer,
and VMware ESX and ESXi. For information about the supported versions, see
the Support Matrix at dell.com/support/manuals.
• Administrator or equivalent permissions.
Introduction to Storage Arrays
An enclosure containing physical disks accessed through RAID controller
modules is called a storage array. A storage array includes various hardware
components, such as physical disks, RAID controller modules, fans, and
power supplies, gathered into enclosures.
One or more host servers attached to the storage array can access the data on
the storage array. You can also establish multiple physical paths between the
host(s) and the storage array so that loss of any single path (for example,
through failure of a host server port) does not result in loss of access to data
on the storage array.
The storage array is managed by MDSM running on a:
• Host server—On a host server system, MDSM and the storage array
communicate management requests and event information using
SAS connections.
• Management station—On a management station, MDSM communicates
with the storage array either through an Ethernet connection to the
storage array management port or through an Ethernet connection to a
host server. The Ethernet connection passes management information
between the management station and the storage array using SAS
connections.
Using MDSM, you can configure the physical disks in the storage array into
logical components called disk groups and then divide the disk groups into
virtual disks. Disk groups are created in the unconfigured capacity of a storage
array. Virtual disks are created in the free capacity of a disk group.

Introduction 9
Unconfigured capacity comprises physical disks not already assigned to a disk
group. When a virtual disk is created using unconfigured capacity, a disk
group is automatically created. If the only virtual disk in a disk group is
deleted, the disk group is also deleted. Free capacity is space in a disk group
that is not assigned to any virtual disk.
Data is written to the physical disks in the storage array using RAID
technology. RAID levels define the way in which data is written to physical
disks. Different RAID levels offer different levels of accessibility, redundancy,
and capacity. You can set a specified RAID level for each disk group and
virtual disk on your storage array.
For more information about using RAID and managing data in your storage
solution, see the
Owner’s Manual at dell.com/support/manuals .
