I'm looking at Resource Governor on 2014 and how it relates to volumes. I can see where to set up MAX|MIN IOPS PER VOLUME on a resource pool. That's not keyed by volume, however sys.dm_resource_governor_resource_pool_volumes is. Should I read that as the pool's definition applies to every volume but the DMV reports what actually happened on each?
My understanding is this: say I have three volumes - E, F and G. I set min = 10, max = 300 on the pool. Then there can be, at most, 300 IOPS against each drive for a max of 900 for the pool. The DMV shows what IO actually happened for each volume. If the table/filegroup definition were such that the majority of the activity happened on one volume (let's say F) the numbers from the DMV would show large
write_bytes_total for that volume and smaller numbers for the others. Is this a correct understanding?
Neither BoL nor any of the blogs I've read make this explicit.
