A data center can contain thousands of assets, from servers, storage and network devices to infrastructure support equipment such as Computer Room Air Conditioners, PDUs and UPSs. Keeping track of these assets is an ongoing task faced by data center managers around the world. A Digital Realty Trust survey found that only 26% of data center managers could locate a server that had gone down within minutes. Only 58% could locate the server within 4 hours and 20% required more than a day. The inability to locate equipment in the data center increases the mean time to repair (MTTR) for the equipment and decreases the overall availability.
