WebSince adding redundancy increases the complexity of a system, efforts to increase reliability and safety through redundant systems may backfire and inadvertently make systems more susceptible to failure. An example of how adding complexity to a system can increase the odds of failure can be found in the near-meltdown of the Femi reactor in 1996. WebRedundancy is an operational requirement of the data center that refers to the duplication of certain components or functions of a system so that if they fail or need to be taken down for maintenance, others can take over. Redundant components can exist in any data center system, including cabling, servers, switches, fans, power and cooling.
