Computational workload-based hardware sizer method, system and program product

摘要

A method, apparatus and program product for determining a required processing capacity to accommodate a computational workload migration from a first computer system to a second computer system is described herein. A processing benchmark for the workload on the first computer system is determined along with a scaling factor for converting the processing benchmark to the second computer system. An adjusted processing benchmark is then determined for the workload on the second computer system and is multiplied by the number of computers in the second system on which the workload is to be run to provide a total processing benchmark for workloads on the second computer system. From the total processing benchmark a mean and maximum utilization factor may be derived to determine the average and peak use of the workload during a predetermined time period. A skew factor may further be derived to represent the excess capacity required on the first system due to the imbalance of the workload across multiple computers. The invention may be repeated for multiple workloads to determine the required capacity for all workloads on the second computer system.
