How to Calculate License Compliancy for IBM

You can calculate your license compliancy position for the IBM software packages using the Processor Value Unit, which is a unit of measure used to differentiate licensing of IBM software on distributed processor technologies. The number of required licenses per processor is determined by multiplying the number of processor chips where IBM software is installed by the number of cores per chip. Then, the resulting value is multiplied by a processor value unit multiplier that IBM provides.

You can also see reports on PVU values if you configure adapters to push certain data to Asset Manager. For more information, see the section describing integrations in the Universal CMDB Discovery and Integrations Content Guide.

1. Locate the scan file data that you want to use for the calculation

   Open a scan file using Viewer. For more information, see Inventory Tools. Then, locate certain data in scan files to determine the vendor and processor technology. To do this, refer to the following table:

   Processor Attributes Mapping

   Generic Name	Universal Discovery Field Name	UCMDB CI/Attribute Name
   Processor Vendor	hwCPUVendor	CPU/CPU_Vendor
   Processor Name	hwCPU_Type	CPU/CPU_Specifier
   Server Model Number (required for IBM only)	hwBIOSMachineModel	Node/Discovered_Model
   Maximum Number of Sockets per Server	hwPhysicalCPUCount	Calculate Raw Count of CPU CI Instances for Each Node
   Processor Model Number	hwCPUDescription	CPU/CPUType
   Processor Type (Cores per Socket)	hwCPUCoreCount	CPU/Core_Number
   	hwPhysicalCPUCount	Calculate Raw Count of CPU CI Instances for Each Node

   Note  

   The values of the fields in the Universal Discovery Field Name column can be viewed by opening a scan file in the Viewer. In the Viewer, the data is contained at Hardware and Configuration > Hardware Data > CPU Data > CPUs or BIOS.

   The values of the fields in the UCMDB CI/Attribute Name column can be viewed at UCMDB > Modeling > CI Type Manager. For more information, see CI Type Manager.

   Use a search engine to map Server Model Number values in the Universal Discovery column or the UCMDB CI/Attribute Name column to the Server Model Number column in the IBM Processor Value Unit table. Enter the value into the search engine and perform basic analysis to derive the correct value.

   The Processor Model Number value is contained in a long string. For example, in the string "Intel(R) Core (TM) i5 CPU M540 @ 2.53GHz"the Processor Model Number value is "M540". To find Processor Model Numbers locally on a discovery node, see more information at IBM Processor Model Number Discovery Guide.

   To calculate Processor Type (Cores per Socket) using the corresponding field in the Universal Discovery Field Name column, use the following calculation:

   [hwCPUCoreCount/hwPhysicalCPUCount]

   If the value is equal to 1, the processor is a single (one) core processor type.

   To calculate Processor Type (Cores per Socket) using the corresponding field in the UCMDB CI/Attribute Name column, use the following calculation:

   [CPU/Core_Number]/Calculate Raw Count of CPU CI Instances for Each Node]

2. Find the processor value unit

   Go to the IBM PVU Licensing table to find the processor technology for which you want to calculate the processor value unit.Then, find the multiplier in the PVUs Per Core column.

   Note Not all processor names are listed in the IBM PVU Licensing table.
