It is a known fact that understanding the IBM licensing is not straightforward and creating an IBM effective license position is the most complex SAM project in the data center. Understanding the various license metrics and calculation methods can actually help us to find a way to solve the licensing puzzle which in turn helps you optimize IBM license costs within the data center.

Why do we need to understand licensing puzzle?

Many projects that use IBM’s ILMT mainly focus on maintaining an inventory of PVU based software deployment but there are other IBM products sold under other license models for which inventory maintenance is complicated.

Software Asset Management (SAM) Tips

  • Understand Sub-capacity

    Sub-capacity licensing allows you to license the IBM’s software product at less than the full capacity of your server or group of servers. But it is required to understand that sub-capacity is not only assigning the license to virtual CPUs used for each IBM application. Instead, IBM will charge you for the accumulated peak virtual capacity for each product used over the last two years.

  • ILMT is compulsory for Sub-Capacity

    When an IBM software is used in virtual infrastructure, ILMT becomes mandatory in order to maintain sub-capacity licensing. To avoid being liable for full capacity licensing, you are required to achieve successful software deployment, configuration.

  • IBM Mainframes are the compliance hotspot

    Although the security systems of IBM Mainframes come with a built-in sub-capacity reporting tool (SCRT), it is a fact that the IBM mainframes are a compliance hotspot where things go wrong easily. Nearly 25% of applications deployed on z system cannot be captured by SCRT. The sub-capacity and Sysplex eligibility ‘traps’ are risky areas that the mainframe users overlook very often. You are required to be proactive to avoid such compliance.

  • There is no one size that fits all solution

    Each server licensing scenario should be solved individually as there is no one license size that fits all your requirements. Each IBM product has a different license requirement on non-production servers. Some product licenses are free, some require full licenses, and some require a reduced, fixed licensing fee.

  • PVU is not the only solution

    Processor Value Unit (PVU) is the most commonly used license type compared to other licensing models. It is difficult to track softwares that are licensed under non-PVU metrics and it contributes nearly 40% of all compliance exposures. To avoid such instances, pay close attention to other licensing models such as

  • Role-Based Authorized Users

    In this license model, a dedicated entitlements are given to each authorized user who can have simultaneous access to any number of instances of the program at one time.

  • Authorized/Employee/External User Value Units (UVUs)

    In this license model, the entitlements are measured based on the number and type of users for a given program. The UVU entitlements cannot be exchanged or interchanged with another program or user as these are specific to one program or the user.

  • Resource Value Units

    In this license model, the entitlements are measured based on the number of units that a specific resource is used or managed by the program. RVU entitlements cannot be exchanged or interchanged with another resource as these are specific to one resource.
