DRS setting question.

One of my cluster DRS is set to “Partially Automated” and often I notice under summary it says Load Imbalanced, and gives recommendation to move VM’s to Balance the load.  My question is if I don’t move them, beside performance, would this impact anything else? Should I change DRS config to “Fully Automated” .. any suggestions would be great… -- thanks.

I have never had any issues with moving stuff around including SQL servers.  If you are worried about it you can set any particular VM to not move by editing the Cluster settings, VMware DRS, Virtual machine options, and setting the individual VM to manual.

I can't think of anything else besides performance that it may affect.  DRS is designed to determine the optimal location for a VM to run so with that in mind I always leave mine at Fully Automated.

Hello.

Note: This discussion was moved from the VMware ESXi 4 community to the vMotion & Resource Management community.

Is there a specific reason you have DRS set to partially automated to begin with?

Good Luck!

Since it is set to 'Partially Automated', it will not move your VMs around for you (other than suggestions). It's usually best to let DRS do its magic unless you have a good reason not to, but as you mentioned the only downsides are performance and your cluster will be imbalanced.

But let me ask you this, if i change the setting to "fully automated" so it will be moving our critical database servers itself, would that not cause any problem? such as drop a ping or etc?
