Virtualization and Cloud Computing: Optimized Power, Cooling, and Management Maximizes Benefits

IT virtualization, the engine behind cloud computing,
can have significant consequences on the data center
physical infrastructure (DCPI). Higher power densities
that often result can challenge the cooling capabilities
of an existing system. Reduced overall energy consumption
that typically results from physical server
consolidation may actually worsen the data center’s
power usage effectiveness (PUE). Dynamic loads that
vary in time and location may heighten the risk of
downtime if rack-level power and cooling health are not
understood and considered.
