Our results show the advantage in performance, cost, and workload consolidation that modern hardware, OSs,

hypervisors, and database software can offer over legacy hardware and software solutions for this workload.

produced the median of three OPM results. Lower CPU percentage and higher OPM numbers are better.

We tested the legacy system with a single database instance running a 10 GB DS2 database, which alone nearly

fully utilized the system's CPU; additional instances yielded unacceptable results. To achieve maximum DS2

results on the Dell PowerEdge R710 solution, we installed one instance of SQL Server 2008 on each of seven

VMs and ran one 10GB DS2 database on each. We show the number of OPM each solution achieved during our

measurement period, minutes 24 through 29 of the test. We calculated the scores by averaging the OPM for each

SQL instance during that period. For the Dell PowerEdge R710 solution, we show the OPM results for the lowest

performing of the seven VMs. Each of the seven VMs on the Dell PowerEdge R710 solution delivered

performance equivalent to or better than the performance of the HP ProLiant DL385.

Figure 6 shows the specific performance results, in both individual VM OPM scores and minimum OPM scores,

for the Dell PowerEdge R710 server with the Dell EqualLogic PS6000 storage array. Higher numbers are better.
