Introduction

NOTE: Throughout the document, Dell PowerVault MD3600f series storage array

refers to both Dell PowerVault MD3600f and Dell PowerVault MD3620f.

This guide provides information about deploying Dell PowerVault MD3600f

and MD3620f storage arrays. The deployment process includes:

• Hardware installation

• Modular Disk Storage Manager (MDSM) software installation

• Initial system configuration

Other information provided include system requirements, storage array

organization, and utilities.

NOTE: For more information on product documentation, see

support.dell.com/manuals.

MDSM enables an administrator to configure and monitor storage arrays for

optimum usability. The version of MDSM included on the MD3600f series

resource media can be used to manage both the MD3600f series and the

earlier generation MD3000 series storage arrays. MDSM is compatible with

both Microsoft Windows and Linux operating systems.

Introduction to Storage Arrays

An enclosure containing physical disks accessed through RAID controller

modules is called a storage array. 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 Fibre

Channel (FC) connections.

8Introduction

• Management station—On a management station, MDSM communicates

with the storage array either through an Ethernet connection to the

storage array management port or though an Ethernet connection to a

host server, which passes management information between the

management station and the storage array using FC 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.

Unconfigured capacity comprises of 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

System Requirements

Before installing and configuring the MD3600f series hardware and software,

ensure that the operating system is supported and minimum system

requirements are met. For more information, see the Support Matrix at

support.dell.com/manuals.

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 (333 MHz or faster) with 512 MB

RAM (1024 MB recommended)

• 1 GB disk space

• Display resolution of 1024x768 with 16 million colors (1280x1024 32-bit

recommended)

Server. Operating system installations can be either native or hypervisior

guest configurations. Supported hypervisors include Microsoft Hyper-V,

Citrix XenServer, and VMware. For information about the supported

versions, see the
