Data Center Redundancy

Data Center operations can be halted by natural disasters or unexpected catastrophic events, such as an earthquake or a fire.

Data Center redundancy refers to the deployment scheme and software procedures an enterprise employs to ensure the continued availability of a Data Center, should this type of disaster occur.

To support Data Center redundancy, the enterprise must maintain two Data Centers:

• Active Production Data Center

• Secondary (or Standby) Data Center

Both Data Centers must be identical in their hardware and software configurations. If a disaster occurs that renders the Active Production Data Center inoperable, administrators need to perform a Data Center switch-over procedure to switch Data Center operations from the inoperable Data Center to the Secondary (or Standby) Data Center. The Standby Data Center then becomes the new Active Production Data Center.
