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). IBM continues to define a processor, for purposes of PVU-based licensing, to be each processor core on a chip (socket). Each software Program has a unique price per PVU. For a complete definition of PVU licensing, please see description of PVU full-capacity and sub-capacity licensing below. For more information about PVUs, see the links to the right under 'Essentials'
