TEST REPORT FEBRUARY 2006 Virtualized OLTP 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 storage TEST REPORT MARCH 2009 KEY FINDINGS z The Dell PowerEdge R710 server and Dell EqualLogic storage supported 22.2 percent more 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 21.4 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 virtualized online transaction processing (OLTP) 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 difference in system architectures and was not a factor in performance as 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 selected the DVD Store Version 2 (DS2) test tool. DS2 is an open-source simulation of an online e-commerce DVD store, where customers login, browse, and order products. Each server under test ran multiple Microsoft SQL Server 2008 workloads, one per VM. One copy of the DS2 database was on each VM, with a 20GB database per VM. By combining multiple virtual machines, all running a CPU, memory, and disk intensive workload, the test placed a heavy load on both the server and the storage. Thus, it measured the performance of the overall solution—server and storage, especially as it relates to an active OLTP environment. The main DS2 metric is orders per minute (OPM). We report OPM results from a 300-second period of steady activity and heavy load during the DS2 test run. The Workload section explains in more detail the Microsoft SQL Server 2008 database workload. Figure 1 compares the peak number of virtual machines running a Microsoft SQL Server 2008 database workload that each server ran with acceptable performance (all VM scores higher than the baseline).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
