Servers: Database consolidation on Dell PowerEdge R810 servers9Savings continue after the payback period. By the end of year one,we project savings of $7,715 with the Dell PowerEdge 810 solution.The Dell PowerEdge R810 solution used a little less than 1/7th ofthe power, 1/24th of the Microsoft Windows Server and MicrosoftWindows SQL Server licenses, under 1/10th of the data center rackspace of the 24 HP ProLiant DL385 solutions, and requires lessadministrator time to manage fewer servers and storage arrays.See Appendix A for more information on these savings andcalculations.224 percent ROI in 3 yearsWe calculate the return on the investment in the Dell PowerEdgeR810 solution by dividing the savings after 3 years, $212,747, bythe acquisition costs, $94,801. ROI is 224 percent after 3 years.The Dell PowerEdge R810 performance story24 databases, 4 instances, 1 serverOur multiple-instance testing with DVD StoreUsing our new hardware environment, which consisted of a singleDell PowerEdge R810 and two Dell EqualLogic PS5000XV iSCSISAN arrays, we installed multiple instances of SQL Server 2008 R2to simulate the benefits of consolidating multiple SQL Server 2000workloads from the HP ProLiant DL385 solutions to the DellPowerEdge R810 solution. To simulate a real-world multi-instanceconsolidation effort, we installed four SQL Server instances andconsolidated six of the legacy workloads per instance on the DellPowerEdge R810. The total number of legacy workloads we wereable to consolidate while still maintaining, on average, the sameoverall throughput as before, was 24.About DVD StoreDVD Store Version 2 is an open-source application with a back-enddatabase component, a front-end Web application layer, and adriver layer that actually executes the workload. DS2 models anonline DVD store. Simulated customers log in; browse movies byactor, title, or category; and purchase movies. The workload alsocreates new customers. Browsing movies involves selectoperations, some of which use full-text search and some of whichdo not. The purchase, login, and new customer stored proceduresinvolve update and insert statements, as well as select statements.The DS2 benchmark produces an orders per minute metric (OPM),which we report in this Guide.
