Virtualization

Virtualization technology allows you to partition one physical server into several virtual servers, or several virtual machines. Each virtual machine can interact independently on the network as though it were a separate physical server. It can also interact with other devices, applications, data and users. Virtualization is possible through the use of a hypervisor. The hypervisor is a program that controls the resources that belong to the physical host, such as the processor and memory. The hypervisor allocates what is needed to the virtual servers, and ensures that they do not disrupt each other.Resource utilization is becoming an increasingly important topic, especially if your business is constrained by poor server and storage utilization. More than likely, you’re over-investing in hardware and wasting space and power, not to mention operational inefficiencies. These in turn increase costs and lead to negative environmental impacts.
You can minimize your capital expenditures by purchasing less hardware using server virtualiztion.

By placing several virtual servers on fewer physical servers, you not only reduce your hardware costs, but also reduce your electricity usage. The management and maintenance of your server infrastructure is also reduced with virtualization. Fewer physical servers need to be managed, and the migration of virtual servers can be as easy as transferring the virtual hard disk files to the new physical server.
In summary, virtualization offers many key benefits to small and medium businesses to help you:

• Reduce IT and energy costs
• Increase server utilization
• Simplify management and maintenance tasks
