If you integrate the Software Asset Management publisher pack for IBM with Software Asset Management providers that are authorized to participate in the IBM Client Value Acceleration (CVA) Program, you can track and manage IBM VPC licenses. Alternatively, you can track and manage these licenses when you integrate with the IBM License Metric Tool (ILMT) or BigFix Inventory using version 2 of the integration APIs.

With these integrations, the publisher pack adds the Virtual Processor Core (VPC) license metric for IBM so that you can calculate licensing for this license type. For more details on Authorized SAM Provider (ASP) integrations, see [Client Value Acceleration (CVA) integrations for IBM](https://servicenow-prod.fluidtopics.net/FYVcGf5v5tnoxIaODAVIHg "Integrate the Software Asset Management publisher pack for IBM with authorized Software Asset Management providers to track and manage IBM licenses across virtualized VMware vSphere and Nutanix environments, and IBM LPAR infrastructures. These integrations help you to track and manage IBM licensing directly without integrating with the IBM License Metric Tool (ILMT) or BigFix Inventory."). For more details on ILMT and BigFix Inventory integrations, see [IBM License Metric Tool (ILMT) and BigFix Inventory integrations](https://servicenow-prod.fluidtopics.net/Mf4xtz1IQA1xv97tffACXQ "You can use an IBM License Metric Tool (ILMT) or BigFix Inventory integration to create a connection between your IBM servers and the ServiceNow AI Platform. Use this connection to import data into your ServiceNow instance so that you can track and optimize licensing for your IBM software products.").

A virtual processor core (VPC) is a unit of measure that enables you to determine the licensing requirements for an IBM software product based on the number of cores that are available to or managed by that product. If you are licensing a virtual machine (VM), VPC is based on the number of virtual cores that are assigned to the
VM. If you are licensing a physical host that is not partitioned for VMs, VPC is based on the number of processor cores on the host. Each VPC license requires one right for every core that is available to or managed by the
associated IBM software product.

If you are integrating the IBM publisher pack with an ASP, the publisher pack supports both full capacity and sub-capacity VPC licensing. If you are integrating with ILMT or BigFix Inventory, the publisher pack supports only sub-capacity
VPC licensing. With a full capacity VPC license, you must account for all processor cores on the physical host that is available to or managed by the IBM software product. With a sub-capacity VPC license, which is available only in virtual environments, you must account for only the virtual cores that are assigned to the VMs on which the IBM software product is installed and running.

You can gain visibility into how your VPC licenses are applied to your devices by using the Usage Type field in the [license workbench](https://servicenow-prod.fluidtopics.net/K_GziLbR~smXeeWp0kcdNw "Review reconciliation results in a simplified workbench view."). Use this information to determine whether your VPC licenses are applied to the full capacity or sub-capacity of each device. If you are integrating with an ASP, you can
specify how a VPC license is applied to a device by navigating to WorkspacesSoftware Asset Workspace. When the Software Asset Workspace launches, open the License operations view. From the left navigation menu of the License operations view, navigate to IBM ASP IntegrationDevice Settings to modify the value of the corresponding Usage Type field. By default, the Usage Type field is automatically set to Sub-capacity.

For more details on the available device settings, see [Verify the meta data for your IBM hosts](https://servicenow-prod.fluidtopics.net/th0dP0FwUWhW6diONOjpXA "To improve the accuracy of your IBM license calculations, verify the meta data for the physical hosts that your IBM software is installed on. Update any meta data that is incorrect or out of date.").
