In today’s highly competitive global marketplace, it is more important than ever for a business to have a distinct advantage over the competition. One way that businesses can gain this advantage is through the effective use of their IT infrastructure and technology resources. Many large organizations have chosen to take advantage of sub-capacity licensing programs offered by IBM, which allow them to leverage their existing hardware platforms to provide greater value at a reduced cost.
What is Sub-Capacity Licensing?
Sub-capacity licensing is a software licensing model used by IBM. It allows users to pay for the capacity they use on-demand, rather than having to pay for the capacity they do not use. Sub-capacity licensing is cheaper than traditional capacity-based licensing. For IBM products, there are several ways you can buy them. You can subscribe to the hardware for a monthly fee. You can buy the software license outright. Or you can choose IBM sub-capacity licensing, an option that allows you to use some capacity of a larger capacity licensed system.
Eligibility for an IBM Sub-Capacity Licensing
To be eligible for an IBM Sub-capacity licensing, customers must attain the following:
- IBM’s License Metric Tool (ILMT) must be installed within 90 days of first use of eligible sub-capacity IBM product.
- Create and maintain quarterly reports (ILMT audit snapshot) for two years at least and make them available at IBM’s request.
How to Succeed with Sub-Capacity Licensing
ILMT supports you to succeed with sub-capacity licensing. The following are the few steps you can follow within ILMT to be successful with Sub-capacity licensing.
1. ILMT – Installation
Many steps need to be done for ILMT to function properly within your environment. The installation process for ILMT consists of six steps, which are as follows:
- Download the ILMT packages.
- Create a server for ILMT and database.
- Install ILMT.
- Deploy agents to servers that are running IBM software. The agents collect information about the server and send it to an IBM system for analysis.
- Configure ILMT.
- Update ILMT with the latest software and Processor Value Unit (PVU) Table.
2. ILMT – Health Check
Once ILMT is installed, the first thing to check is your agent deployment health. By managing and tracking agent health, you can ensure the deployment of ILMT in your environment remains healthy/complete.
3. ILMT – Software Classification
There are two ways of classifying software: manually and automatically, but given a large number of applications, ILMT must rely on automatic methods. When ILMT scans a machine, it identifies the software components installed. It then makes its best guess as to which product those components belong to.
Often, default component-to-product assignments are incorrect. These classifications are listed as “Pending” software. Every default assignment must be changed from “Pending” to “Completed”. To change this, you are required to review the assignments and reassign them to appropriate products.
4. ILMT – Thresholds
Once the software classification is complete, you can set entitlement thresholds to notify you when a product is out of compliance. The product license you set needs to match the entitlements you own for that product.
5. ILMT – Audit Snapshot
To apply for sub-capacity licensing, you must create and maintain quarterly reports for two years at least and make them available at IBM’s request
