9. As explained during the tests we collected multiple performance metrics. Following the
completion of tests on all virtual machines we analyzed the results in terms of – AQRT, CPU
utilization, TPS. Based on the analysis userload supported is determined. Results of the
R820 VM infrastructure are compared against the results of legacy production environment.
10. Based on the comparison analysis between PowerEdge 2950 and R820 we derived the
consolidation factor, power savings etc.
