Moving to RHEL from AIX (licensing question)

[Michel de Kraker]

Goodday,

Currently we are running CMOD on AIX.

AIX lpars are running in dedicated processor pools apart from other applications running on the same POWER system.
This reduces the licensing costs significantly.

When we go to RHEL on VMWARE , we do not have the capability of dedicated processor pools if I understand correctly.
In fact , when you are in a VMWARE farm of let's say total of 96 processor you will be charged for 96 processors.

Does this seems logical or am I completely wrong? Is there someone who is running on RHEL/VMWARE and has some licensing info?

Thankyou for your thoughts.

Kind regards

Michel.

This would be a great question for your IBM Software Rep.

On multiplatform, OnDemand is typically licensed by user, not CPU.

@rjrussel, you are correct. it is user based so no difference between aix and rhel regarding licensing cost.

regards

Michel

Based on your license types. (e.g. AUVU, PVU, ...)

AUVU (Authorized User Value Unit): This counts the number of unique users added to the IBM CMOD system. The number of AUVUs purchased must not be exceeded by the number of users in the system.

PVU: Processor Value Unit - IBM has reference table to calculate brand/number-of-core to PVUs.
Intel core will use less PVU than POWER-core half-by-half as I remembered.
(ex. Intel 4-cores=70PVU, POWER 4-cores=140PVU ..this may not actual values just example)

This licensing model requires the use of ILMT (IBM License Metric Tool) to track and report the number of CPU cores in your LPAR/VM, ensuring compliance with the number of PVUs purchased.

Also, they have some more license model -- RVU, Employee VU, ..

However, double check with IBM sale representative for your license usage.
