Not sure when this happened, but IBM has now tiered the PVU requirements, which also affects Domino. This affects Intel CPUs (AMD are still all 50 PVUs per core)

Basically this tiered approach requires you to have a higher number of PVUs per core the more sockets you have in a single server. It's basically this:

<= 2 sockets : 70 PVUs per core (this is also any 5xxx series Xeon)

3 & 4 sockets : 100 PVUs per core

> 4 sockets : 120 PVUs per core

So just when you thought there was no way on earth you could hate the evil that is PVU, well....you were misguided. This seems to be a high end server tax, but maybe I'm just jaded (look at the link below.....jadeAction....erm....) and see this as a way to wring dollars out of audits.....or not. It's worth pointing out that some of these servers could have the same model of CPU, but the more sockets you add to a single server, the more you add to the higher the PVU "tax". More than eyebrow raising.

Anyway all the details are here:

Switch to CEO licences. They are counted by user and allow unlimited CPU and servers. Comes in tasty bundles.

We moved to CEO licensing a few years ago. So glad we did.

But CEO is calculated on all users able to access a PC capable of running Notes regardless of it they do or don't...so if you can cope with only 1 cluster of 2 servers, then I would propose Express which is based on the actual number of registered Notes users (and cheaper than CEO!).

We have recently helped two 100+ seat customers dump their existing licences and start again with Express because of the associated costs of installing some new hardware ( that was not even that powerful.

There are some good deals about.
