Patent ID: 8856332

Claim:
A method implemented in a computer infrastructure having computer executable code, comprising: consolidating collected capacity architecture information, which comprises data for installed resources, allocated resources and reserved resources; determining available resources based on the collected capacity architecture information; and performing capacity planning based on the collected capacity architecture information and the available resources, wherein: the reserved resources are a first plurality of resources selectively assigned to a first resource configuration by a first user and prevented from selection by other users for assignment to other resource configurations; the collected capacity architecture information further includes at least one of fixed system capacity information and virtualized system capacity information; the collected capacity architecture information further includes an oversubscription factor; the reserved resources are reserved from the installed resources for capacity planning purposes and not yet activated; the available resources are the installed resources excluding the allocated resources and the reserved resources; and the installed resources comprise fixed logical partitions (FLPARs), logical partitions (LPARs), and fixed logical partitions-variable (FLAPR-v); and wherein the method further comprises: receiving a request for capacity planning for a particular on-demand datacenter from an architect of the on-demand datacenter; collecting capacity architecture information for resources of the on-demand datacenter, the resources of the on-demand datacenter including the installed resources, allocated resources and reserved resources; generating at least one of a layout structure view and a configuration view of the on-demand data center; performing test scenarios by altering at least one of the reserved resources, an oversubscription factor, and an entitled capacity, the scenarios including added capacity requested by the architect of the on-demand datacenter; reserving a plurality of the resources of the on-demand datacenter corresponding to a selected one of the scenarios, the plurality of resources including the added capacity; and generating buildsheets and architectural drawings for a configuration of the on-demand data center based on the selected one of the plurality of scenarios.
