Principled Technologies, Inc.: Dell PowerVault MD3000i high-availability testing on

Windows Server 2008 R2 and Hyper-V

• File server (active but not under load)

Dell PowerEdge R710 #2

• Microsoft SQL Server 2008 (active and under DVD Store load)

• File Server (active and under Iometer load)

• Microsoft SharePoint (active but not under load)

• File server (active but not under load)

• Microsoft IIS (active but not under load)

• Microsoft Systems Management Server (active but not under load)

• Secondary Microsoft DHCP Server—different scope (active but not under load)

• Microsoft SQL Server (active but not under load)

We configured the virtual machines with the following settings:

SQL Server

• 4,096 MB memory

• 4 virtual processors

• SQL Server 2008 SP1

• Window Server 2008 R2

• 1 Active SQL Server

• 1 user = 3-4 operations per minute

• 1 thread = 10 users

• 200 users: 20 threads (approx. 800 OPM)

• 500 users: 50 threads (approx. 2,000 OPM)

• 1.5 seconds think time

Exchange Server

• 4,096 MB memory

• 4 virtual processors

• Exchange Server 2008 SP2

• Window Server 2008 SP2

• 1 Active Exchange Server

• 200 average (as defined by LoadGen) users

• 500 average (as defined by LoadGen) users

All other virtual machines

• 2,048 MB memory

• 1 virtual processor

Test results

We report the performance results on the applicable test tool for each Dell PowerEdge R710 server running on

the Dell PowerVault MD3000i in both an optimized and degraded system state.

DVD Store results

Figure 3 shows the number of OPM the second Dell PowerEdge R710 server and the Dell PowerVault MD3000i

achieved during our measurement period of the DVD Store test on the median run. We calculated the scores by

averaging the OPM during the 30-minute period. As we have discussed, the theoretical peak performance for our

DVD Store workload is four operations per minute per user, for both the 200- and 500-user counts. With four

virtual machines under load, and 12 background virtual machines, all running simultaneously, the Dell PowerVault

MD3000i solution was able to sustain near maximum theoretical SQL Server 2008 operations per minute: 760 or

758 OPM at 200 users and 1,878 or 1,868 OPM at 500 users.
