TEST REPORT
OCTOBER 2009
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.
