Do I need to create one single thinpool (of what size ?  size estimates follow ) or do i create separate pool for Timefinder snap usage ??..this vmax is dumped with all the data which currently is existing in the environment as soon as the migrations start imagine the data is about 27 TB. so Do I create the thinpool with little more than 30 TB? or what is the best practice here. The source devices which are going to be snapped is about 4 TB, what is the best approach for thinpool creations meeting above requirements ??

once the pool is created somehow, in order to meet the growing demand, we tend to add data devices to the pool, also there is a need to rebalance the pool with added tdats. (Is adding tdats and issuing rebalance no way effects the connected host with existing storages right?)

Last what are the subcription percetages to be put for the created pools ?
