Dell PowerVault DL2000 Backup Performance

A Dell Technical White Paper

Dell PowerVault DL2000 Powered By Symantec

Muffadal Quettawala and Scott Reichmanis

Introduction

The Dell PowerVault ™ DL2000 – Powered by Symantec Backup Exec

is a exible, cost-effective backup solution for simple, manageable

data protection.

This whitepaper evaluates the throughput performance capabilities

of the PowerVault DL2000 in its two hardware congurations – Value

Series and Performance Optimized1. With this information, the

end-user will be able to accurately size their backup infrastructure

to meet backup window requirements by scaling the number of

DL2000s needed for their environment and by optimizing backup

schedules and balancing backup workloads.

The PowerVault DL2000 Performance Optimized version was

evaluated in a six (6) Gigabit Ethernet (GbE) port conguration and

the DL2000 Value Series version was evaluated in both a six (6) GbE

port and a two (2) GbE port conguration. The backup client system

infrastructure consisted of a Microsoft® Exchange Server 2007

environment and a Microsoft® SQL Server® 2008 environment as

illustrated in Figure 1 below.

The DL2000 – Powered by Symantec also comes in four (4) different software editions but they have no

impact on backup throughput, and hence are not compared in this whitepaper.

The maximum backup throughput achieved for each of the three

system congurations is summarized in the table below:

These results provide an end-user with valuable data and insight for

planning, sizing and using the DL2000 Backup to Disk Appliance

within their IT infrastructure.
