5 tips for a good set-up of your IBM License Metric Tool

ILMT IBM

If you’re an IBM customer, you probably heard about IBM License Metric Tool (ILMT) – a tool that can make the software licensing more flexible by enabling you to take advantage of the opportunities offered by virtualization. Nevertheless, many IBM customers are struggling with the installation, set-up and tracking of ILMT, often resulting in compliance issues.

While Oracle is notorious for its aggressive approach to VMware virtualizations, IBM is generally more flexible. If you use ILMT, you can rest assured that you don’t have to pay for all the physical cores of your servers, as with Oracle, but only for the virtual CPUs being used (sub-capacity).

To enable and simplify counting those virtual CPUs, IBM provides ILMT for free. Although using ILMT offers the possibility to only license the sub-capacity of a server, it also comes with obligations. For example, if you cannot provide the number of (virtual) CPUs in use, you can expect a huge back payment in case of an audit. Depending on the size of your organization, this may imply millions of euros that are obviously not budgeted for. IBM customers who want to benefit from virtualization should therefore not ignore ILMT. In this article you will find some practical tips to help you make good use of the tool.
