Dell PowerVault MD3000i high-availability testing on

Windows Server 2008 R2 and Hyper-V

KEY FINDINGS

• The highly-available Dell PowerVault

MD3000i solution easily supported our

various 200- and 500-user virtualized SMB

workloads. (See Figures 1 and 2.)

• The highly-available Dell PowerVault

MD3000i solution maintained outstanding

performance in both optimized and

degraded system states. (See Figures 3

and 4.)

• Our testing assumed all users were

running our four application workloads

simultaneously, meaning that the Dell

PowerVault MD3000i solution can easily

exceed our maximum of 500 simultaneous

users if running a similar workload under

real-world conditions.

Executive summary

Dell Inc. (Dell) commissioned Principled Technologies (PT)

to determine whether the Dell™ PowerVault™ MD3000i

iSCSI storage array in a high-availability configuration can

support small (200-user) and medium (500-user)

organizations simultaneously running a variety of virtualized

workloads in both an optimized and degraded system state.

We created a highly available solution with two Dell™

PowerEdge™ R710 servers, both running Windows

Server® 2008 R2 with Hyper-V as the underlying

hypervisor, using cluster shared volumes. Each Dell

PowerEdge R710 ran eight Windows Server 2008 R2 virtual

machines (VMs). The first Dell PowerEdge R710 ran a

Microsoft® Exchange 2007 virtual machine (which we ran

the Microsoft Load Generator test tool against), a file service

virtual machine (which we ran an Iometer workload against),

and six other background virtual machines that were active

but not under load. The second Dell PowerEdge R710 ran a

SQL Server® 2008 virtual machine (against which we ran the DVD Store test tool), an additional file service

virtual machine (against which we again ran an Iometer work load), and six other background VMs. We ran the

workloads simultaneously on each Dell PowerEdge R710 server with two different user counts: 200 and 500

simulated users. We assume these users are performing mail, database, and multiple file server operations

simultaneously. This means our testing exceeded real world conditions, where users would tend to exercise the

business infrastructure in a more sequential manner. We present more information on our test tools in the

Workload section of this report.

We installed a combination of

commonly-used Microsoft

applications on our background

virtual machines (those VMs that

were active but not under load),

including Microsoft SharePoint®,

Microsoft Internet Information

Server, Microsoft DHCP server,

and Microsoft Active Directory®.

We list all of the specific

applications we used in the

Workload section below.

Figure 1 presents the SQL Server

2008 performance results of the

Dell PowerVault MD3000i solution

in supporting a 200- and 500-user

count workload in an optimized

system state, where both servers

in our Windows 2008 R2 Hyper-V

cluster are operational and are

supporting virtual machines.

Figure 1: SQL Server 2008 Performance results of the Dell PowerVault MD3000i solution

in supporting 200- and 500-user count workloads in an optimized system state. Note:

We expect OPM to continue to rise linearly until the system is under maximum load. We

did not test maximum load for this study.
