Processor Value Units (PVUs)
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.
PVU tables
The tables below list existing generally available processor technologies only, as of the published date. PVU requirements for future processor technologies may differ. For help identifying your Processor Model Number, check the Processor Model Number Discovery Guide (US).
Note:
- Each Integrated Facility for Linux (IFL) or Central Processor (CP) engine is equivalent to 1 core.
- Refers to System z9, eServer zSeries, or System/390 servers.
- Entitlements required for Power Processor Element (PPE) cores only.
- The PVU requirement for the POWER7/7+ processor technology is dependent on the maximum possible number of sockets on the server. NOTE: Power 7 Refers to Power 7/7+ 5
- z196 refers to IBM zEnterprise 196, zEC12 refers to IBM zEnterprise EC12.
- z114 refers to IBM zEnterprise 114.
- Cell Broadband Engine is a trademark of Sony Computer Entertainment, Inc. in the United States, other countries, or both and is used under license therefrom.
- Intel, Intel logo, Intel Inside, Intel Inside logo, Intel Centrino, Intel Centrino logo, Celeron, Intel Xeon, Intel SpeedStep, Itanium, and Pentium are trademarks or registered trademarks of Intel Corporation or its subsidiaries in the United States and other countries.
PVU Table per Core (section 1 of 2 - RISC and System z)
Note:
- IBM offers Software for both Intel and AMD processors. Intel refers to its processors by "Processor Number" and AMD by "Model Number". The processor model can be preceded by a letter. For example, 'x5365 refers to '5365', which is included in the table within the '5000 to 5499' range.
- The PVU requirement for the Intel processor technology indicated is dependent on the maximum number of sockets on the server. If sockets on two or more servers are connected to form a Symmetric Multiprocessing (SMP) Server, the maximum number of sockets per server increases. See single server examples and two or more servers example below.
Single server examples:
- 2 socket server with 6 cores per socket requires 840 PVUs (70 per core x 12 cores )
- 4 socket server with 6 cores per socket requires 2400 PVUs ( 100 per core x 24 cores )
- 8 socket server with 6 cores per socket requires 5760 PVUs ( 120 per core x 48 cores)
Two or more servers with connected sockets example:
- When sockets on a 2 socket server with 6 cores per socket are connected to sockets on another 2 socket server with 6 cores per socket, this becomes an SMP server with a maximum of 4 sockets per server and 24 cores, and requires 2400 PVUs (100 per core x 24 cores).
