VMware vSphere

Hi everybody,

Based on the link below, we can have maximum 115 msec  round trip time for vMotion.

Out of curiosity, what happens if we violate this limit?

Thanks and have a good day!!

If you have the proper license applied to your environment, you can perform reliable migrations between hosts that are separated by high network round-trip latency times. The maximum supported network round-trip time for vMotion migrations is 150 milliseconds. This round-trip time lets you migrate virtual machines to another geographical location at a longer distance.

You get failures and very odd problems.

Moderator: Moved to vSphere Discussions, not a HA or FT question.

If you are fortunate the vMotion will complete but the VM will just run extremely slow. If you are unfortunate the vmotion will be cancelled half way down. Either way, we don't support this.
