Superseded — Virtual Processor Core (VPC)
Catalog row in Vendor License Metrics · Draft
- Unit
- VPC
- Aliases
- VPC; Virtual Processor Cores; vCPU (IBM: In IBM licensing, a vCPU is also referred to as a Virtual Processor Core (VPC)). Sub-capacity page: For VPCs: 1 VPC equals 1 virtual CPU (vCPU).
- Definition
- Virtual Processor Core (VPC) is a unit of measure by which the Program can be licensed. A Physical Server is a physical computer that is comprised of processing units, memory, and input/output capabilities. A Virtual Server is either a virtual computer created by partitioning the resources available to a Physical Server or an unpartitioned Physical Server. A Processor Core is a functional unit within a computing device that interprets and executes instructions. A Virtual Processor Core is a Processor Core in an unpartitioned Physical Server, or a virtual core assigned to a Virtual Server.
- Counting rules
- Deploy using full capacity, sub-capacity, or container licensing if supported. Sub-capacity: same lower-of virtual vs physical cores as PVU; then 1 VPC equals 1 virtual CPU (vCPU). With PA v11, sub-capacity reporting that applied to PVU/RVU now applies to VPC for new customers 1 Feb 2023 and existing 1 May 2023. Effective 10 May 2022, VPC sub-capacity requires ILMT or approved tool; Manual capacity counting will no longer be permitted. Failure to comply is charged at full capacity of activated physical cores. Container licensing is not included in that VPC policy change. Container guidance separately states 1 VPC = 1 vCPU and 70 PVU = 1 vCPU for container licensing only. IBM does not publish a global VPC-to-PVU table for traditional (non-container) VM licensing. The container 70 PVU = 1 vCPU ratio does not apply to VM sub-capacity.
- Floors / minimums
- Same whole-core minimum as other core-based metrics (Sub-Capacity FAQs: one whole processor core). Container: pod fractions allowed; cluster-level aggregation rounded up to nearest whole integer (Container Licenses page).
