- Statement
- IBM Virtualization Capacity counting rules (retrieved 2026-08-31; primary source): license “the maximum number of virtual cores in the virtual machines (VMs) available to the Eligible Product at any given time” (or physical host capacity when virtual exceeds physical). Sub-Capacity FAQs Overview (supporting): “An increase in the maximum or peak processor core capacity, as measured in cores, available to the IBM software requires additional license entitlements.” “IBM licensing terms do not allow for averaging processor core capacity or temporary spikes in workload.” “Both full and sub-capacity licensing terms requires the maximum (peak) processor core capacity for the server (full) or partition (sub-cap) prior to deployment or increase in that capacity.” ILMT “reports this so that customers can ensure that they have obtained sufficient entitlements to cover these ‘high water marks’.” No grace-period true-up (FAQ). FAQ is educational; primary cite is the sub-capacity policy page.
