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

A computer program product readable by a digital processing apparatus and tangibly embodying a program of instructions executable by the digital processing apparatus, said computer program product comprising:

• a computer readable medium having recorded thereon computer readable program code for performing method steps for determining a processing capacity requirement based upon a migration of computational workload from a first computer system to a second computer system, the method steps comprising:
• a. determining a processing benchmark representing the processing capacity required for said computational workload on said first computer system;
• b. determining a scaling factor for relating said processing benchmark for said computational workload on said first computer system to an adjusted processing benchmark for said computational workload on said second computer system;
• c. deriving said adjusted processing benchmark for said computational workload on said second computer system by combining said processing benchmark for said computational workload on said first computer system with said scaling factor;
• d. deriving a total adjusted processing benchmark for said computational workload on said second computer system by multiplying the adjusted processing benchmark by the number of computers on said second computer system which are to run said computational workload;
• and
• e. multiplying the total adjusted processing benchmark by a maximum utilization factor to produce a maximum processing benchmark.
