Over the past year I have seen a downward trend in Used accessible data while I have been adding servers, storage and luns.

I would like to know how ECC polls this particular field. The report I run is a monthly Arrays report. All of the other fields are in line. I would assume by adding more servers and luns my Used Allocated would also increase. Our based up data has grown 47% and according to my last year of trending with ECC, our Used Accessible data field has shrunk by 43%.

Is this field pulled from the attached host? Should all of my servers being reported against in ECC have the Master agent and appropriate host agent installed? I have also migrated a lot of data to a Celerra ~8TB, will this be polled as well?

I have concerns that my reporting is not accurate.

As a quick example, one of my XC-380's shows 4.5TB used accessible and one of my NAS gateways has 6TB used on that array so my trending is way off!

Any insight would he great...
