AVAILABILITY
Since the last decade, the concept of design for availability has been backing up pure MTBF-based reliability analysis,
which can be used to define the quality of a single system or piece of equipment. Availability assessment is now preferably
carried out at site level, by checking the impact of random failures on the infrastructure’s ability to keep supplying the
IT loads. This is also referred to as “outcome based” availability. Following the above trend, in modern Data Centers a
single power feed, even if including UPS units, is no longer considered reliable enough to provide the desired power
quality, so multiple layers of redundancy are usually deployed.
