Battery – Jones, 2014, notes that although batteries
provide an instant transfer of clean power, batteries
account for a significant source of failure for UPS
systems. There can be multiple reasons for battery
failure, including limited service life, frequency of use or a
lack of maintenance.
Rotating Mass – As an alternate to batteries, Amiryar
and Pullen, 2017, note that rotating mass or ‘flywheel’
technology involves the inertia of a spinning mass
providing energy to a load. While the reliability of a
rotating mass may be more than a battery, the duration
that a rotating mass can maintain any load may be quite
limited.
Reliability
Colocation data centers rely upon multiple systems. A
failure of any key non-redundant system could result in
the data center power loss. Automatic, redundant and
serviceable systems; highly trained personnel; ongoing
training; and scheduled proactive maintenance are
the key factors to consider when selecting a reliable
colocation data center.
