How does virtualization help with disaster recovery within a data center?
- Hardware does not have to be identical.
- Server provisioning is faster.
- Less energy is consumed.
- Power is always provided.
- (Other case) Hardware at the recovery site does not have to be identical to production equipment.
Explanation: Disaster recovery is how a company goes about accessing applications, data, and the hardware that might be affected during a disaster. Virtualization provides hardware independence which means the disaster recovery site does not have to have the exact equipment as the equipment in production. Server provisioning is relevant when a server is built for the first time. Although data centers do have backup generators, the entire data center is designed for disaster recovery. One particular data center could never guarantee that the data center itself would never be without power.
