A Processor Value Unit (PVU) is a unit of measure used to differentiate licensing of middleware based on distributed processor technology (defined within the PVU table by Processor Vendor, Brand, Type and Processor Model Number).
Sub-capacity licensing lets you license a PVU-based software program for less than the full processor core capacity of the server, when the software program is deployed in an eligible virtualization environment. With full capacity licensing, customers are required to obtain PVU license entitlements for all activated processor cores in the server, regardless of how the software was deployed.
IBM’s Passport Advantage Sub-Capacity Licensing offering
- enables customers to leverage server virtualization to more effectively consolidate their infrastructure and reduce their overall total cost of ownership (TCO)
- allows flexible software licensing using advanced virtualization capabilities such as shared processor pools, micro-partitioning, virtual machines and dynamic reallocation of resources
- gives growing customers the flexibility to choose how to add workload environments without making trade-offs between hardware design and software licensing
enables customers to license software for only the processor core capacity available to the partition hosting the IBM software
provides a tool (ILMT) which allows the customer to track and manage the processor core capacity available to IBM PVU-based middleware
