Abstract:
1. A method of allocating workload among servers in a geographically collocated cluster of compute equipment, said method comprising steps performed by a computer system of: calculating a first heat re-circulation level resulting from a first server utilization level of the compute equipment; calculating a second heat re-circulation level resulting from a second server utilization level of the compute equipment, wherein the first and second heat re-circulation levels are measures of an infiltration of heated airflow into cooled airflow prior to the heated and cooled airflow being supplied into one or more of the servers; calculating a heat re-circulation factor (HRF) for the cluster of compute equipment from the first heat re-circulation level and the second heat re-circulation level, wherein the HRF is a ratio of the difference in heat generated at the first server utilization level and at the second server utilization level over the difference in the heat re-circulation generated at the first server utilization level and at the second server utilization level; and allocating workload among the servers based upon the calculated heat re-circulation factor.
