The company I worked for purchase a large number of "MQ Processor Value Units” back in the day. People who calculated these PVUs are long gone and we now have a license renewal coming up.
Based on IBM website, this is the formula for Red Hat Servers: sockets x cores x 70.
Our calculation doesn't get anywhere near the number of PVUs we purchased (our is roughly a third of what we purchased).
I wonder if there are other things that need to be taken into account when it comes to PVU calculation, for example number of Queue Managers per box
If indeed we purchased more than we needed, could use them for our license renewal?
Please help 
Thanks

PVU calculation is only based on CPUs, and not number of queue managers or anything else. You will need to negotiate with your IBM sales rep. We can't comment on your license agreement.

This site runs on Red Hat and we've just renegotiated our contract for 2016 (don't laugh - it's taken a while - we have a lot of IBM software). So I have bitter and hard won experience of calculating PVU requirements on RHEL.

If you agreed to purchase a given number of PVUs "back in the day", and that was more than you ended up actually needing, and you've been paying for all those unneeded PVUs from then to now, I would be pleasantly surprised and slightly shocked if IBM gave you a refund. Caveat Emptor and all that.
They certainly don't give us a refund, which is why we spend so much time calculating how many we need. Paradoxically, you use more PVUs than you purchase and it's like the sky opens to release a rain of fire.....

Thank you so much @gbaddeley and @Vitor.
Probably I can add a little bit of background information. We have been live for 2 years now. We purchased software licenses for our system from a big company in the US and they helped us providing us with things like the PVU calculation.
In addition to the license renewal we also have an IBM audit coming up next week and the consultant company that IBM hired to audit us is asking us a lot of questions, including this PVU calculation. Unfortunately I don't think I can ask them whether they think we are paying more than we should for our licenses.
To be continued. I will provide with an update after all is said and done. |

There are PVU Calculators on the IBM website. Feed in the System details and out pops the PVU's.
If your consultant says differently, say 'Prove it!. I got these directly from IBM.'
As for the IBM audit, do the same. They have to justify their report on your site.
IF they do not agree with the IBM site take it to your sales rep.
If you are sure that you have paid more than you should then you are in a strong position with IBM and more importantly, with the company that sold you the licenses in the first place.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Be aware you may have bought more PVUs than you are *currently* using, to make sure you have enough for later.
Also you may have PVUs for non-production systems.

ILMT (IBM License Management Tool) can be deployed on all your servers to take inventory of all installed IBM software and PVU consumption. I suggest that you talk to IBM.

Thanks for the input. The calculation is actually correct, what is wrong is what I put in my post.
Anyway Audit went reasonably well and now we are waiting for the final report.
It seems a little too late to ask for a refund but going forward I expect we will to be spending at the most 1/3 of what we currently are.  |

IBM will do what it can to keep the customer satisfied. If not dollar refunds, IBM frequently offers training coupons.
