Performance Brief for IBM WebSphere Application Server 7.0 With VMware ESX 4.0 on HP ProLiant DL380 G6 Server

By virtualizing the server environment, one can improve server utilization and consolidate servers onto high capacity virtual machines. This allows to reduce the cost to maintain and manage the server infrastructure. Virtualization also allows to migrate data and applications among servers more quickly and efficiently. The VMware ESX 4.0 server takes maximum advantage of available cache and memory locality as in 2 and 4 core virtual machine scenarios. The performance delta between the physical and virtual configuration is significantly reduced with the latest Intel Xeon X5570 (Nehalem) processor over previous tests with IBM WebSphere Application Server and the Apache DayTrader application.
