Rohang, slight correction on your reply..  The subscription value of a pool is the ratio of the capacity of the thin devices bound to the pool to the capacity of the pool itself.  A pool can be oversubscribed but not fully allocated meaning there is still free space in  the pool.  The allocation % will change as tracks move out of the tier due to fast VP movement but the actual subscription will not change.  Please refer to [URL]
Hi,  I am looking for an information regarding the subscription % of a pool in a VMAX40K.   --> I have 1x Lun of 1000Go, i bind it in the middle tier and activate FAST, by policy 200Go goes into EFD.   Question #1: Will the subscription % of the middle tier pool change after the data has been move to EFD or other pools ? Question #2: What happen if you disable FASTVP completly ?  Will all the storage capacity that FASTVP sent to other pools by policy will return                     automatically to the BIND pool (middle tier) ?  Thank you,  Christian Carrier
