Installing traditional physical servers would normally require a separate server for each server role. Server virtualisation can overcome this issue by housing multiple virtual servers on one physical server where they can efficiently run multiple different operating systems in parallel.
Server virtualization requires software like Microsoft Hyper-V (or VMWare), which is included in the latest Microsoft Windows Server software. However, you will need a (new) server capable of running a 64bit operating system i.e. Windows 2008, 2012. The good news is the majority of new servers are a lot more energy efficient.
Virtualising servers will result in improved resource utilisation as well as reductions physical space, power and cooling requirements. In addition to energy saving reducing the number of servers will lower capital expenses due to more efficient use of hardware resources. Virtualisation provides high availability of resources, increased security, and improved disaster recovery processes.
The majority of new servers we install or host use the virtualised platform because is highly scalable. Adding additional virtual servers as your company grows does not incur the same project, labour or capital costs as adding additional physical servers. Virtualisation can also improve the effectiveness of a disaster recovery plan.
Employing fewer physical servers means that virtualisation reduces not only capital and management costs but also on-going maintenance costs and energy consumption. As energy bills increase companies are endeavouring to save on energy consumption and reduce their carbon footprint.
