SCVMM Cloud Capacity Limitations don't match what OS reports

Question

So, in SCVMM we're going to be using clouds to limit how much resources different business groups can consume. I've created a number of clouds, and when VMs are created within them, each cloud reports a "Utilization" in the overview pane, basically
saying how much resources are being consumed by that cloud.
My plan was to divide our total capacity into clouds so that business owners could use automation to manage their own VMs, the problem is that as far as Storage Utilization goes the number that SCVMM has is not exactly what the OS is reporting. For example,
a file is say, 60GB, but with compression, deduplication, or whatever else the "Size on disk" is substantially smaller than the "File Size". Whether it's because of this, block size, or anything else what this means is SCVMM is thinking
we're running out of space much faster than we actually are. Is there a way to tell SCVMM to go off what the operating system is reporting the "size on disk" is, instead of what SCVMM things the size is?
The only current solution I can think of is to make the sum of my quota's or "cloud capacity" greater than what it physically is... which means if the difference between size on disk and size isn't consistent, I am going to run out of space.

Answer 1

So, as far as I can tell there is no work-around. We actually got fantastic savings, 7TB of VMs only took up like 3TB even after we turned them on. What we did was overprovision and give the quotas more than the total physical room. We provisioned a 14TB
lun and so far have still used less than 4TB, and my quotas are all based on 14TB of capacity.
