Unformatted text preview: +Store. Each client VM ran a single instance of DS2, which spawned 32 threads, and used a 15:1 search-to-order ratio, which we implemented via the provided n_searches parameter in DVDStore. This simulated a heavily loaded environment; the load-generating client VMs ran with no think time, blasting requests as quickly as the servers could handle them.

While the DVDStore client application outputs OPM at 10 second intervals visually, we chose to collect this OPM metric via a Performance Monitor counter on each client VM at one-second intervals. We ran this workload on all virtual machines simultaneously for 30 minutes. We considered a solution to have delivered acceptable performance if the minimum OPM score on every client VM during the 23 to 28 minute period of the test was above the baseline OPM. Test results Figure 3 shows the peak number of virtual machines each solution could handle during testing before dipping below the acceptable threshold and the minimum client score from the median run. Based on our analysis and experience with DS2, we set the baseline at 2,600 OPM. Each VM on both the PowerEdge R710 and ProLiant DL385 G5 had to score a minimum of 2,600 OPM to be valid.
