In a recent survey released by Emerson Network Power, UPS battery failure was found to be a leading source of data center downtime.
A rather remarkable 65% of data center managers survey saw UPS failure as the largest cause of data center downtime. UPS capacity was seen as the culprit 53% of the time and human error was sited at 51%.
450 data center operation professionals were interviewed. They reported an complete outage occurred 2.48 times over a two year period. Even the big boys, centers with more than 20,000 square feet saw a total failure rate of 1.75 times over two years.
