I have a two node cluster and using DRS. In the DRS settings under "Fully automated" there's a slide bar for the "Migration Threshol". The default setting is in the middle. I have three questions for this....
1: In the middle setting, how long does DRS allow the runaway server to eat up CPU before doing a vMotion?
2: From the middle and sliding one tick to the right closer to "Aggressive", how long does DRS allow the runaway server to eat up CPU before doing a vMotion?
3: When set all the way to "Aggressive", how long does DRS allow the runaway server to eat up CPU before doing a vMotion?
Thanks
It is not so much how long will it take for DRS to vMotion - the driving factor on whether DRS will vmotion is if the VMs are not getting their entitiled resources - so if you do have a 'run away' vm and the ESX server it is on is able to provide the necessary resources the VM will stay where it is at - check out page 67 of http://www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_resource_mgmt.pdf
