TEST REPORT FEBRUARY 2006 Virtualized Exchange workload performance comparison of end-to-end solutions: Dell PowerEdge R710 with Dell EqualLogic storage vs. HP ProLiant DL385 G5 with HP StorageWorks EVA 4400 TEST REPORT MARCH 2009 KEY FINDINGS z The Dell PowerEdge R710 server and Dell EqualLogic storage supported 25 percent more Microsoft Exchange 2007 virtual machines than did the HP ProLiant DL385 G5 server and HP StorageWorks EVA 4400 storage. (See Figure 1.) z The Dell PowerEdge R710 server and Dell EqualLogic storage had a 29.9 percent performance-per-watt advantage over the HP ProLiant DL385 G5 server and HP StorageWorks EVA 4400 storage. (See Figure 2.) Executive summary Dell Inc. (Dell) commissioned Principled Technologies (PT) to compare the virtualized Microsoft Exchange 2007 workload performance of two server-and-storage solutions: Dell PowerEdge R710 server and Dell EqualLogic storage HP ProLiant DL385 G5p server and HP StorageWorks EVA 4400 storage The Dell PowerEdge R710 solution had two 2.4GHz Intel Xeon E5530 processors and 72 GB of RAM while the HP ProLiant DL385 G5 solution had two 2.7GHz AMD Opteron 2384 processors and 64 GB of RAM. (The Dell PowerEdge R710 currently supports up to the 2.93GHz Xeon X5570 processor.) The difference in the quantity and speed of RAM in the systems was due to the system architectures and was not a factor in performance because each virtual machine (VM) was limited to 4 GB of RAM. We connected the Dell PowerEdge R710 to the EqualLogic storage via iSCSI and connected the HP ProLiant DL385 G5 to the EVA 4400 storage via Fibre Channel. We installed build 148592 of a version of ESX still under development as the hypervisor for each server. ESX build 148592 supports the new virtualization technologies such as Intel VT Extended Page Tables (EPT). For this comparison, we used Microsoft Exchange LoadGen 2007, a Microsoft-provided tool for benchmarking an Exchange Mail Server. We defined the peak number of VMs per server as the maximum number of concurrent VMs under load where each VM had acceptable performance. Figure 1 compares the peak number of virtual machines running a Microsoft Exchange 2007 workload that each solution ran with acceptable performance. The Dell PowerEdge R710 ran 10 such simultaneous VMs, while the HP ProLiant DL385 G5 ran 8 such simultaneous VMs. Each VM contained 4000 users for a total of 40,000 users on the Dell PowerEdge R710 and 32,000 users on the HP ProLiant DL385 G5. Thus, the Dell PowerEdge R710 solution had a 25 percent performance advantage over the HP ProLiant DL385 G5 solution. 0 2 4 6 8 10 12 Peak number of virtual machines Virtualized Exchange 2007 workload results Higher results are better HP ProLiant DL385G5 server and HP StorageWorks EVA 4400 storage Dell PowerEdge R710 server and Dell EqualLogic storage Server and storage solution Figure 1: Microsoft Exchange 2007 workload performance results for the two solutions.
