Migrating Server Workloads to Red Hat Enterprise Virtualization on Intel® Xeon® Processor 2600-based Servers for Performance and Cost Improvements

Continued enhancements to Intel platforms and KVM-based Red Hat Enterprise Virtualization make platform refresh an attractive proposition. Independent testing commissioned by Intel and Red Hat demonstrates that open virtualization on refreshed servers, servers 2 years old or more, enables workloads to be supported on fewer hosts, reducing equipment and facilities requirements, as well as lowering operational expenses such as power, cooling, and support.

Server Refresh with Intel® Xeon® processor E5-2690 and Red Hat Enterprise Virtualization:

A Simple Path to Dramatic Performance and Cost Improvements Continued enhancements to Intel platforms and KVM-based Red Hat Enterprise Virtualization make platform refresh an attractive proposition, but when to make the move? Intel and Red Hat commissioned Principled Technologies, a technology assessment and testing firm, to quantify some of the potential benefits. A middleware application was moved, without changes, from a bare-metal server based on the Intel® Xeon® processor 5500 series to a virtual machine (VM) under Red Hat Enterprise Virtualization 3.1 on the Intel® Xeon® processor E5-2690. The VM delivered 90.3 percent greater application performance than the previous-generation bare-metal server. Even more dramatic results were generated by running a second, identical (but isolated) VM on the newer host: 143.8 percent greater application performance compared to the bare-metal server. Each VM had 16 virtual cores and 24 GB of virtual RAM, matching the 16 logical cores and 24 GB RAM on the bare-metal server. Both the VMs and the bare-metal server ran Red Hat Enterprise Linux* 5.8.2. This result demonstrates that open virtualization on refreshed servers, servers 2 years old or more, enables workloads to be supported on fewer hosts, reducing equipment and facilities requirements, as well as lowering operational expenses such as power, cooling, and support.

Server Refresh: Migrating Server Workloads to Red Hat Enterprise Virtualization on Intel® Xeon® Processor 2600-based Servers

Principled Technologies, a technology assessment and testing firm, virtualized a middleware application running on Red Hat Enterprise Linux hosted on a previous-generation bare-metal server onto a Red Hat Enterprise Virtualization VM on a two-socket server powered by Intel® Xeon® processors E5-2690. The migration caused minimal disruption and the single VM increased performance over the previous-generation server by 90.3 percent, with headroom to host additional applications. When a second VM was added to take advantage of the headroom, each VM still outperformed the previous-generation server, indicating that moving previous-generation servers to VMs backed by Intel® Xeon® processors E5-2690 can significantly improve overall Java performance while providing the benefits of both virtualization and new server technologies.
