Powering a data center

A method of operating a data center, comprising:

• deploying a first plurality of computers to a data center;
• operating the first plurality of computers in the data center, each of the computers having a peak power draw;
• distributing power to the plurality of computers through a power distribution network having a power capacity, wherein the power capacity is less than a maximum power draw defined by summing the peak power draw from each of the plurality of computers;
• subsequently to deploying the first plurality of computers, deploying a second plurality of computers to the data center comprising between approximately 7% and approximately 46% of the first plurality of computers, such that a maximum power draw defined by summing the peak power draw from each of the computers in the first and second plurality of computers is greater than the power capacity, and an operating power draw defined by summing an actual power draw from each of the computers in the first and second plurality of computers is less than the power capacity, the first plurality of computers being operable while the second plurality of computers is being deployed;
• prior to deploying the second plurality of computers to the data center, determining an amount of the computers in the cluster of computers of the second deployment installed in the data center subsequent to the first deployment of the plurality of computers is based, at least partially, on a workload type executing on the computers;
• and
• prior to deploying the deploying a second plurality of computers to the data center, determining the amount of the computers in the cluster of computers of the second deployment installed in the data center subsequent to the first deployment of the plurality of computers is further based, at least partially, on a percentage of operating time of the computers in the first and second deployments spent in a power-capping mode.
