DRS migration priority

Does anyone know at what priority does DRS migrate hosts? Low-priority or High-priority?

When manually VMotioning a host, one has an option. I am wondering what method DRS uses.

I don't know, but considering time used to migrate machine in my infrastructures, i think "high".

You are basically going to almost always migrate with a "high" priority. If you use a low priority, it basically takes it sweet little time and migrates it when it feels it has the time and the free resources to make that move. That isn't the exact techincal answer, but usually when you want to vmotion a box, you tend to want to do it now.

Since DRS is basing its moves by its own internal resource algorithms, I don't believe it has the same concept of priority as when you do a manual vmotion. It is constantly measuring load and decides where the load needs to be, and moves the workload.

I always leave the option in default, this way he never caused me any problems in the host and is not moving at all times.

But I believe that if he stands on high and migrates often can generate a problem in ESX servers or on the Virtual Center, depending on the number of VMs.
