VMWare Virtualisation

As a company grows and accumulates different servers over its network, there comes a time when server rationalisation and future requirement planning become inevitable. With recent improvements in virtualisation technology, VMWare server virtualisation is now a sensible option for the forward-looking IT administrator planning for the future.

There are many good reasons for a small or medium business to consider moving over to virtualisation and a VMWare server network. Server consolidation, outgrowing your servers, disaster recovery, Simpler server deployment, the use of multiple operating systems, increased server efficiency and smaller energy bills are just some of the advantages that come to mind.

Server virtualisation means partitioning one physical server into several virtual servers, or machines. Each virtual machine can interact independently with other devices, applications, data and users as though it were a separate physical resource. Different virtual machines can run different operating systems and multiple applications while sharing the resources of a single physical computer. Because each virtual machine is isolated from other virtualised machines, if one crashes, it doesn't affect the others.

VMWare Hypervisor software is the ingredient that makes virtualisation possible. This software, also known as a virtualisation manager, sits between the hardware and the operating system, and decouples the operating system and applications from the hardware. The hypervisor assigns the amount of access that the operating systems and applications have with the processor and other hardware resources, such as memory and disk input/output. VMware is the market leader in virtualisation. VMWare's technology is production-proven and used by more than 170,000 customers, including 100% of the Fortune 100.

  • Save money. With virtualisation, you can turn a single purpose server into a multi-tasking one, and turn multiple servers into a computing pool that can adapt more flexibly to changing workloads.
  • Save energy. Businesses spend a lot of money powering unused server capacity. Virtualisation reduces the number of physical servers, reducing the energy required to power and cool them.
  • Save time. With fewer servers, you can spend less time on the manual tasks required for server maintenance.
  • Reduce desktop headaches. Desktop virtualisation solutions let you manage user desktops centrally, making it easier to keep desktops updated and secure.
