Traditionally server utilization has only been in the range of 18%. This means that there is a huge amount of wasted computing power in most enterprises. With the popular concern over CO2 emissions and energy conservation, virtualization is truly a concept whose time has come. CCSI Virtualization Servers are optimized for hosting multiple homogenous or heterogeneous virtual server instances. They generally have high performance, multi-core CPUs, with hardware virtualization, and much more RAM than general purpose servers require since each hosted server instance requires at least a minimal amount of RAM. With modern dual processor Xeon™ or Opteron™ servers running VM Ware, KVM or ZEN hypervisors it is not uncommon to host twenty or more server instances on a single physical server. This allows a considerable reduction in TCO resulting from savings in hardware acquisition and maintenance costs, operational energy consumption, cooling infrastructure expenses, and personnel expenses. These savings can be rolled into establishing mirrored or clustered servers with fail over support yielding greater system reliability than could ever be achieved with traditional stand alone servers built with redundant hardware. When you consider the advantages, mirrored virtualized servers are quite compelling; especially in an era of tight IT budgets. Another relatively recent development in virtualized servers that also benefits from powerful servers loaded with RAM is Microsoft Remote FX which is supported in Windows Server 2008. Remote FX allows the “heavy lifting” to be done by a remote server with a high performance video card (or several of them). This allows technical jobs such as engineering and CAD rendering to be done from a remote location while the computing power and data remains in a more secure central location allowing easier maintenance and regular backups. Telecommuters benefit from not having to shuttle a powerful computer workstation to and from the office while the enterprise benefits from a greater level of control and greater server utilization.
