VMTurbo OVF template comes with default 4 CPU, 16GB Mem and 150 storage... can u downgrade these resources to 2CPU's , 8GB and some thing around 50GB of storage?
Yes, you can. This default spec is designed to support somewhere around 10-14,000 VM's and so if you have a smaller environment then feel free to tune the VM size down. Two things to watch out for.....the real time operation of the solution is in-memory and so you don't want that to run out and also please make sure that you don't run out of disk space as that will also handicap the system (however, if you ensure that the VMTurbo VM is thin-provisioned then you have no benefit to reducing the default disk allocation and so maybe leave it as default).
There are health checks run automatically within the solution in these performance areas and you will see system events appear in the bottom right of the console (image below) if you hit performance or disk space issues. Alternatively, you can of course SSH to the VMTurbo VM using root/vmturbo credentials to check this manually in the OS.
One other piece to note is that after about 24-48 hours VMTurbo will start to populate recommendations to downsize virtual machines based on the demand for resources. This is even true about the VMTurbo instance itself!
If you look under the Improve Overall Efficiency Dashboard there could be a recommendation to size down your VMTurbo instance in the next day or so. Now you can allow VMTurbo to control VMTurbo because it understands its own mem/cpu usage as well as the demand of every other virtual machine.
See below for such a recommendation:
