I have 2 sites with 2 Hyper-V clusters. I'm running System Center VMM in Dublin which monitors my servers in the USA. If I want to do a storage migration from one LUN to another on my USA cluster, will the script run from the Hyper-v Servers or from the VMM server in Dublin?

Will there be a latency problem or will it run in the local server?

I'm preparing to do a test myself but if someone has the answer I'd appreciate it

The script could be run from any of the servers as long as it can find the locations to which it is pointing to. I would prefer to run it from the VMM host, since that's your monitoring machine.

As for latency, there should be no difference (unless you have network issues) because you mentioned the migration is performed between 2 LUNs located within the same site.

EDIT

As long as you're not migrating to or from your VMM host, the operation is only controller by the server but not executed by or through it.

  • Hey, Thanks for the reply. Because the VMM server is managing the cluster on the other side of the atlantic. If I create a storage migration from the VMM server. do you think it will buffer the copy to the VMM server before copying to the new LUN or copy direct? I hope this makes more sense Commented Feb 24, 2015 at 17:46

  • Thanks for the reply, I had guessed that was the way it should work logically. But had to be sure. Thanks for the reply Commented Feb 25, 2015 at 9:39
