How Many More VMs Can Be Provisioned (Accuracy?)

Post by StuartW_D » Jun 06, 2017 5:21 pm

Hi All,

As anyone come accross this report not giving you a figure you would expect?

For example my cluster is averaging roughly 55% for both CPU and Memory, Network is well below is maximum and I have switched off the Datastore aspect of the Reporting.

I have set max vCPU to 4 and selected a moderately busy VM to use as a model.

When the report Generates its says I can add 0 more machines.

Any ideas of any metrics I might be missing that I need to check that influences this calculation?

Regards,
Stu

And I believe I am being a dummy. That vCPU ration I needed to up and then you will see provisioning numbers :)

Ill have to read up what is a good ratio to have? I assume that the default is recommended and as long as your CPU Ready is below 5% and Avgerages are decent?

Any recommendations on that ratio?

Hi Stuart,
The described results make sense. As far as I know the max. recommended value of vCPU per physical CPU is 8. So try to keep that number between 4 and 8.
Thanks!
