Subject AW: Free capacity calculation within ACS
Date Wed, 06 Sep 2017 07:42:50 GMT
Hello Marc-Aurèle,

great. Didn't know that this parameter exists.
Do you know in which ACS version this got introduced?

Many thanks.
Ingo

Hi Ingo,

You might want to look at the release period set in your installation:
host.reservation.release.period. This release window time is there to keep the capacity of
stopped machines on a host for a certain time, before releasing it, in case the machine has
to start again soon after. And most likely for other reason maybe in the advance networking
mode. So try to decrease this time window and check your capacity after that.
