Initial investment payback analysis: DellPowerEdge R710 solution with VMware ESX vs.HP ProLiant DL385 solutionTEST REPORTMAY 2009KEY FINDINGSz Each Dell PowerEdge R710 solution withVMware® ESX™ can replace seven HPProLiant DL385 solutions, and couldyield a payback in under 18 months.(See Figure 1.)z The Dell PowerEdge R710 solution withVMware ESX delivered seven virtualservers, each of which yieldedperformance equivalent to or better thanthe performance of one physical HPProLiant DL385 solution. (See Figure 4.)z The Dell PowerEdge R710 solution withVMware ESX used little more than 1/5thof the power, about 4/5 of the softwarecosts, and 1/7th of the data center rackspace of the seven HP ProLiant DL385solutions. (See Figures 3 and 7.)Executive summaryDell Inc. (Dell) commissioned Principled Technologies (PT)to estimate how many months it would take to recaptureinitial investment costs when consolidating multiple 4-year-old HP ProLiant DL385 server and storage solutions onto aDell™ PowerEdge™ R710 server and storage solution usingVMware ESX. In this report, we estimate both the number ofolder solutions each Dell PowerEdge R710 solution canreplace and the payback period for replacing those oldersolutions. We compare the following two solutions:• Intel® Xeon® Processor X5550-based DellPowerEdge R710 server with 96 GB of memoryusing VMware ESX and Dell™ EqualLogic™PS6000XV storage (Dell PowerEdge R710 solution)• AMD Opteron 254-based HP ProLiant DL385 G1server with 4 GB of memory and HP StorageWorksMSA30 storage (HP ProLiant DL385 solution)Our test case modeled a typical enterprise datacenter with multiple legacy HP ProLiant DL385 solutions runninghigh-demand database workloads. The legacy servers each used 4 GB of memory. The enterprise in this testcase seeks to consolidate several of these legacy workloads onto Dell PowerEdge R710 solutions using VMwareESX and configured with sufficient processors, memory, and storage to handle these workloads.We used benchmark results from the Dell DVD Store Version 2.0 (DS2) performance benchmark to determine thenumber of older servers with accompanying storage that a Dell PowerEdge R710 solution could replace. Todefine the replacement factor, we measured the number of orders per minute (OPM) that the HP ProLiant DL385solution could perform when running a demanding DS2 workload. We then ran DS2 in virtual machines (VMs) onthe Dell PowerEdge R710 solution and measured how many VMs this newer solution could run, while obtainingFigure 1: A single Intel Xeon Processor X5550-based Dell PowerEdge R710 solution with VMware ESX allows you to consolidateseven AMD Opteron 254-based HP ProLiant DL385 solutions, with an initial investment payback period of under 18 months. We basethis estimation on our specific database workload.
