Safe-Hot-Swap is not just the ability to exchange UPS modules on a live system, it is the facility for this to be completed safely and to mitigate any human error. CumulusPower’s Distributed Active Redundant Architecture (DARA) ensures any module being added to a system can be fully isolated and tested within a running frame before it accepts any load. In a system without safe-hot-swap, any issue with a module going into a live system could have catastrophic consequences and the load could be lost.
CumulusPowerTM also reduces TCO through high double conversion efficiency of >97.1% and offers 99.9999999% (nine, nines) availability, reducing downtime to only 3.5 milliseconds per year. There is a significant difference between this and the most commonly used architecture of 99.9999% (six nines) that allows for 31.5 seconds of downtime. This means that CumulusPowerTM is currently the safest and most reliable UPS available for power protection.
