Virtualisation can reduce the burden of disaster recovery
12/08/2009
The implementation of virtualisation can reduce the burden of disaster recovery, it has been claimed.
According to IT professional John Savill, the major factor which makes virtualisation an effective way to keep the likelihood of implementing a disaster recovery programme down is that it reduces the number of physical machines that need to be dealt with.
Writing for FAQ for Windows, Mr Savill said that if companies go from 50 physical machines to just ten virtual servers, they will reduce the number of restorations they have to do in the event of downtime by 80 per cent.
He added: "With virtualization, your "hardware" is all virtual and completely separated from the actual, physical hardware in the host server. This separation means it's much easier to take a virtual machine and restore it to different hardware."
Meanwhile, businesses implementing managed hosting services such as cloud computing have found that virtualisation means that memory capacity is no longer a bottleneck as the issue of hardware density is negated.
