Abstract:
Large-scale Internet services require a computing infrastructure that
can be appropriately described as a warehouse-sized computing
system. The cost of building datacenter facilities capable of delivering
a given power capacity to such a computer can rival the recurring
energy consumption costs themselves. Therefore, there are
strong economic incentives to operate facilities as close as possible
to maximum capacity, so that the non-recurring facility costs can be
best amortized. That is difficult to achieve in practice because of
uncertainties in equipment power ratings and because power consumption
tends to vary significantly with the actual computing activity.
Effective power provisioning strategies are needed to determine
how much computing equipment can be safely and efficiently
hosted within a given power budget.
