Patent ID: 8301315

Claim:
A method of scheduling cool air jobs in a data center, the data center comprising computers whose operations produce heat and require cooling, cooling resources that provide cooling for the data center, a workload controller that schedules and allocates data processing jobs among the computers in the data center, a cooling controller that schedules and allocates cooling jobs among cooling resources in the data center, the method comprising: assigning by the workload controller data processing jobs for execution by computers in the data center, a time when the workload controller assigns each data processing job defining a data processing workload schedule; providing, from the workload controller to the cooling controller, information describing data processing jobs scheduled for allocation among the computers in the data center, the information including the physical location of the computer to which each job is allocated, the quantity of data processing represented by each job, and the data processing workload schedule; specifying, by the cooling controller in dependence upon the physical location of the computer to which each job is allocated and the quantity of data processing represented by each job, cooling jobs to be executed by cooling resources, each cooling job comprising a quantity of cool air to be delivered to a physical location in the data center; and assigning, by the cooling controller in accordance with the workload allocation schedule to cooling resources in the data center, cooling jobs for execution.
