Who needs ILMT?
Customers who have licensed IBM software products on a processor value unit (PVU) basis and are running these products in a virtualized environment are required by the terms of their licenses to use IBM’s license metric tool (ILMT) to monitor capacity usage. ILMT applies if you are using the sub-capacity licensing model, only paying for the virtual CPUs allocated to the software, and not on a full-capacity basis (licensing all CPUs on the physical host). ILMT applies to both Production and non-Production environments.
There are four exemptions to the ILMT requirement:
1. ILMT does not support the customer’s eligible virtualization technology.
2. The customer’s worldwide enterprise has fewer than 1,000 employees and contractors, excluding Service Providers, and customers who have contracted with a Service Provider to manage their virtualized server environments.
3. The customer’s total physical capacity of their servers with Sub-capacity licensing within their worldwide enterprise is less than 1,000 PVUs.
- Based on the definition of “servers” below, this would include all servers in a specific VMWare or Hyper-V Cluster (defined below) whether or not an IBM product is running on them.
- ILMT Recommended by IBM
4. The customer’s servers, with PVU-based products that are eligible for Sub-capacity licensing, are licensed to the full capacity of the servers.
Summary of ILMT Requirements
There are several requirements provided in the IBM Passport Advantage Agreement (IPAA) for sub-capacity licensing qualification. You must:
1. Install and configure the ILMT within 90 days of your first use of an eligible sub-capacity product in an eligible virtualization environment (or comply with the manual usage tracking requirements if you qualify for such an exception)
2. Produce, on a quarterly* basis, the required reports; retain such reports for at least two years; and make them available to IBM upon IBM’s request.
Exception Reporting Requirements
For the above exceptions, customers must manually manage, track, and prepare audit reports.
- An audit report must be prepared at least once per quarter using the Worksheet for Manual Calculation of Virtualization Capacity (link provided below).
- Audit reports must identify Each Eligible Sub-Capacity Product deployed in each Eligible Virtualization Environment.
- In addition, the report should provide a summary total of the required number of PVUs by and for each Eligible Sub-Capacity Product.
- Audit reports must be prepared as frequently as is required to maintain a history of increases to Virtualization Capacity and Full Capacity.
- Each audit report must be generated at least once per quarter.
Manual Tracking Requirements
- Customers must manually manage, track, and prepare a Manual Calculation of Virtual Capacity worksheet for each server.
- The worksheet is available here.
- Audit reports implemented in ILMT 7.5 and ILMT 9.0 fulfill the requirements from Passport Advantage sub-capacity license agreements regarding audit reports.
- Once per quarter – minimum audit report creation frequency
- The Sub-capacity terms reflect quarterly reporting as the maximum amount of time allowed before having to analyze and reconcile ILMT reports.
- Most customers will probably need to perform this effort on a monthly basis. Some customers with very dynamic server environments (e.g., where partitions are resized/moved frequently and/or with changes in their software inventory) may need to create weekly reports in order to keep up with the volume of change.
- Only customers with the most stable of virtualized server environments would be able to maintain compliance with IBM licensing terms by doing quarterly reports.
- Two years – mandatory maintenance period for created audit reports.
- The audit report is digitally signed and ready to audit after creating an audit snapshot on All IBM Metrics audit report panel.
- Audit report creation is always a manual action and cannot be scheduled.
- A group of servers, that are linked together using vCenter Server or Microsoft.
- Failover clustering feature to provide resources (i.e., processor core capacity) to the virtual machines (VMs).
- A machine that provides resources (i.e., processor core capacity) to the VMs.
- Includes single standalone servers or servers within clusters or resource pools.
