Server Virtualization needs high demands of CPU, storage, and the entire server system usage. Let us see what can make them a real performer. We have already published about the Server Virtualization capable processors which has the features to increase performance of the virtualized servers. AMD-V in the Opteron processors and Intel VT-x in the Xeon Processors have these features.
Benchmark is also available for the performance of Server Virtualization like VMmark from VMware. Manufacturers gives importance to achieve the best possible test values.
Server Virtualization and VMmark
Independent Server Virtualization benchmarking efforts started in 2007. VMware together with industry partners maintains this Server Virtualization benchmark for VMmark.
VMmark allows a standardized comparison of the performance of Server Virtualization. VMmark consists of six typical server workloads, which are created with standard tools for load generation. Each workload is running in its own virtual machine.
Performance of 2, 4 and 8 sockets Server Virtualization
Server with two processors are the primary area of ?AMD’s Opteron and Intel’s Xeon. Server Virtualization with four socket processors from AMD and Opteron series of Intel Xeon are high performers. Eight processor sockets are available from AMD and Intel Xeon 7000 models that are available.
All these above listed can be said to be capable of high performing Server Virtualization.
Hard Disk and Physical Memory
Obviously for Server Virtualization the main component is the processor. However, the other important parts for a high performance server are Hard Disk, motherboard and Physical Memory.
A physical RAM of 192 GB or more is required for higher performance from any Server Virtualization environment. Among the other points, Server Virtualization and cooling is very important part as when the system becomes very hot, the performance decreases.
We have discussed ago about various cooling methods for the datacenters running Server Virtualization, you might read the article as well.
