01 — IBM Licence Models

PVU, RVU, VPC & Other Licence Metrics

IBM uses some of the most complex licensing metrics in the software industry. PVU, RVU, VPC, floating, token-based, and subscription models each have distinct rules that determine your cost — and getting the metric wrong is the most common source of audit exposure.

🔢
PVU

Decoding IBM PVU Licensing: A Comprehensive Guide

Processor Value Units (PVU) are IBM's core licensing metric for distributed middleware. Understand how PVU values are assigned to processors, how sub-capacity works, virtualisation rules, and common PVU compliance mistakes.

Read Guide
📈
RVU

Mastering IBM RVU Licensing: A Complete Guide

Resource Value Units (RVU) measure consumption based on the resources managed — not the hardware running the software. Understand RVU calculation methods, common products using RVU, and optimisation strategies.

🔄
Floating & Token

Subscription

Non-Production

IBM Non-Production Licensing: Dev, Test & DR

Bundling

02 — ILMT & Sub-Capacity Licensing

ILMT Compliance & Sub-Capacity Reporting

IBM's sub-capacity licensing allows you to licence based on virtualised capacity rather than full server capacity — but only if you deploy and maintain ILMT correctly. Failure to comply with ILMT requirements reverts you to full-capacity pricing, which can multiply your licence cost overnight.
