Hi
For a cluster where DRS is enabled, does VMware DRS checks at some regular intervals on a cluster to see if the workloads under different ESX hosts needs to be re-distributed?? Or would the auto-mirgation takes place as soon as DRS thinks that the workload is not evenly distributed among the ESX hosts under the same cluster?
Thanks.
I understood this was every 5 minutes.
Can someone confirm this for me please.
Stuart is correct,
It scans the cluster every 5 minutes.

Also take a look at the presentation of Nitin Suri at vmworld 2006 (tac 9413)
The best thing since sliced bread: effective DRS and HA in production http://download3.vmware.com/vmworld/2006/tac9413.pdf
The other thing to note is it will always balance load using CPU utilisation before RAM.
Thanks guys for all the good information.
