Building in standby power redundancy for greater protection levels
For greater assurance of 24/7 power availability at all times standby power ‘redundancy’ has now become commonplace in many systems which require 99.99% uptime.
Redundancy is often included within a standby power system at UPS level but can also be added at generator level to ensure that should there be a failure within one system there is always a secondary back-up system able to accept the power load. This can also be beneficial during maintenance where if one system is being serviced, there is always a “live” system available should mains power fail.
Commonly termed “N+1″ (incorporating 2 mirrored systems) standby power redundancy can be extended even futher to N+2 or even N+3 configurations to cover ultra-critical systems and provide almost 100% “guaranteed” power cover should standby power be required.
Redundancy is essential for mission-critical applications, such as in datacentres or in demanding environments such as industrial process control where down-time for any reason is a costly and unwelcome interruption.
In an IT environment this design is complementary to the RAID array and hot-standby fileservers and like those technologies is directed to removing single point-of-failure weaknesses.
