Automatic CPU Balancing accross vPars -- WLM or Home-Grown Script?

[Alzhy]

Anyone using WLM in a vPar scenario to automticall balance CPUs accross vPars on a single Frame? Is it an add-on $$$ feature?

I am thinking, we can perhaps just use a Home-Grown Script to perform the same end result. Has anyone done this thing yet?

Thanks!

Hi Nelson,

The WLM is available as an add-on product (with some $$$ required) or as part of the MCOE (Mission critical OE).
Some time ago I was thinking of venturing into this, but somehow it didnt happen.So sorry not answer to your primary question.
You may have already referred to docs regarding WLM - but still here is one from me.

I actually already have some sort of a prototype WLM-like script that based on a set of rules (i.e. maxima minima CPU's and load rules), CPUs are automtically moved to a vPar that needs them. It runs from a different machine of course - and what it does is periodically collect CPU stats of the vPars. If the script senses 1 vPar needs CPUs to bring it to an acceptable %CPU utilization, it checks the other vPars if they could give up CPUs (also based on a set CPU utilisation rule)...

I know WLM probably has some more bells and whistles but all we really need is a facility to balance CPUs accross vPars on a single frame. In our case, the subject frame is a single nPar SuperDome (8-Cell/64-core) that will be carved into 5-6 vPars.
