Why Use a UPS?
Organizations of all shapes and sizes need UPSs as part of their fault-tolerance strategies. A UPS is as important as any other fault-tolerance measure. Three key reasons make a UPS necessary:
-
Data availability The goal of any fault-tolerance measure is data availability. A UPS ensures access to the server in the event of a power failureor at least as long as it takes to save a file.
-
Protection from data loss Fluctuations in power or a sudden power down can damage the data on the server system. In addition, many servers take full advantage of caching, and a sudden loss of power could cause the loss of all information held in cache.
-
Protection from hardware damage Constant power fluctuations or sudden power downs can damage hardware components within a computer. Damaged hardware can lead to reduced data availability while the hardware is being repaired.
