I noticed that only one esxi in the cluster  is going to standby mode from time to time, it could be something to do with DPM.
Is it advisable to turn the DPM off instead of automatic?

If DRS/DPM calculates you do not need the resources, it will put hosts into standby. - this is by design.

Depends on your companies "green policy", and if you are trying to save energy and electric.

We do not have many clients, which have DPM turned on!
