Power Redundancy

Redundancy is defined by Merriam-Webster as, “a part in a machine, system, etc., that has the same function as another part and that exists so that the entire machine, system, etc., will not fail if the main part fails [25]”.

Due to the required uptime associated with most mission critical operations, they can require having extra power on hand in case of unexpected outages. This extra power is often discussed in terms of redundancy levels. Redundancy levels are most commonly used to refer to power and cooling systems and their components.

Redundancy Levels
Level | Represented by Level
N (stands for number) | represents the base requirement
N+1 | represents the base requirement plus one additional
N+2 | represents the base requirement plus two additional
2N | represents two additional for each base requirement
2(N+1) | represents two N+1 systems
