A Processor Value Unit (PVU) is a unit of measure used to differentiate licensing of software on distributed processor technologies (defined by Processor Vendor, Brand, Type and Model Number).

Full versus Sub-capacity

Licensees can deploy Eligible Programs using either Full Capacity licensing or Virtualization Capacity (Sub-Capacity) licensing.

  • If using Full Capacity licensing, the Licensee must obtain Processor Value Unit (PVU) entitlements sufficient to cover all activated processor cores in the physical hardware environment made available to or managed by the Program, except for those servers from which the Program has been permanently removed. An Activated processor core is a processor core that is available for use in a physical or virtual server, regardless of whether the capacity of the processor core can be or is limited through virtualization technologies, operating system commands, BIOS settings, or similar restrictions.
  • If using Sub-Capacity licensing, according to the Passport Advantage Sub-Capacity Licensing Terms the Licensee must obtain entitlements sufficient to cover all activated processor cores made available to or managed by the Program, as defined according to the Virtualization Capacity License Counting Rules.

Processor Value Units (PVUs)

A Processor Value Unit (PVU) is a unit of measure by which the Program can be licensed. The number of PVU entitlements required is based on the processor technology (defined within the PVU Tables below by Processor Vendor, Brand, Type and Model Number) and by the number of processors made available to the Program. IBM defines a processor, for the purpose of PVU-based licensing, to be each processor core on a chip (socket). A dual-core processor chip, for example, has two processor cores.
