Virtualising a datacentre can make it more flexible, but it also introduces new points of failure and it doesn't remove the need for critical servers to be duplicated for fail-over, disaster recovery (DR) specialist Neverfail has warned.
The warning came as replication and DR companies lined up to promise support for Microsoft's Hyper-V server virtualisation technology, which was formally launched along with a companion management tool, Microsoft System Centre Virtual Machine Manager 2008.
"VMM is Microsoft's tool to manage a virtual infrastructure, it's their equivalent of the VMware tool VirtualCentre, but it is also a new point of failure," said Andrew Barnes, Neverfail's senior VP for corporate development.
"Virtualised infrastructures bring their own management challenges. In this case, the difficulty is if you put your VM management tool onto a virtual platform, and that platform dies, you lose so much functionality."
