Patent ID: 8126751

Claim:
A computer-implemented method for allocating system costs applicable on every part of an infrastructure of a computer center, wherein the infrastructure includes at least one peripheral device and at least one arithmetic unit, the method performed on at least one computer having a computer readable medium having stored thereon instructions, which, when executed by a processor of the computer, causes the processor to implement the method, comprising: determining, on the processor of the computer, total costs in proportion several parameters of individual system resources of the infrastructure for a billing period, wherein the total costs include a cost for the at least one peripheral device that is determined based on a specific usage of a service for which the at least one peripheral device is used; dividing, on the processor of the computer, the total costs in proportion several parameters of individual system resources into cost shares of individual performances of system resources by a key; dividing, on the processor of the computer, the cost shares of individual performances of system resources into individual performance shares of system resources made use of by individual services, such that the division corresponds to a percentage share of the individual performance of a system resource actually used by an individual service; adding, on the processor of the computer, the individual performance shares for each service for each system resource, thereby providing performance share sums; and adding, on the processor of the computer, the performance share sums, which have been formed each for the same service but different system resources.
