The Irish Independent reports that Irish data centre
energy costs are to exceed property costs by 2010, according
to a study carried out by market research firm iReach.
iReach estimates that data centres require 0.5 to
1 watt of cooling power for each watt of server power used
and that a typical x86 server consumes between 30pc
and 40pc of its maximum power when idle.
In addition, a typical rack of servers installed in data
centres just two years ago might have consumed a modest 2kW
of power while producing 40 watts of heat per square foot,
according to data from Sun Microsystems' engineers.
However, newer, high-density racks - expected as 'standard'
by the end the decade - could easily consume as much as 25kW
and give off as much as 500 watts of heat per square foot,
Sun said.
The energy consumed by fans, pumps and other cooling components
already accounts for some 60-70pc of the total energy consumption
in the data centre and iReach predicts that energy
costs will become the second highest cost in 50pc of Ireland's
data centres by 2010.
It is now believed that in most data centres - particularly
those in single-story buildings - electrical costs are already
more than two to three times greater than the property costs.
