(In CLI, the value is the delta, whereas here it is the actual date and time.) Calculating Capacity for StoragePool and StorageVolume Calculate capacity for StoragePool and StorageVolume through one of the following methods. Primordial Storage Pool The primordial pool represents the raw capacity of the array. Its TotalManagedSpace therefore represents the capacity of all the disk drives in the array, whether admitted or not, minus capacity lost due to chunklet formatting. The RemainingManagedSpace option represents the capacity of the disks that are in a New state, namely those that have not been admitted. StoragePool.SpaceLimit has the same value as TotalManagedSpace. Concrete Storage Pool TPD_AllocatedFromStoragePool.SpaceConsumed between a primordial and a concrete pool (3PAR:all-FC, 3PAR:all-NL or 3PAR:all-SSD) represents the raw capacity taken by the concrete pool. The capacity used for metadata in the creation of the concrete pool can be calculated by (TPD_AllocatedFromStoragePool.SpaceConsumed - ConcreteStoragePool.TotalManagedSpace). TotalManagedSpace for a concrete storage pool represents the raw capacity that can be used to create storage volumes, dynamic storage pool, or delta replica storage pool. RemainingManagedSpace for a concrete storage pool represents how much raw capacity is available for creating a new volume, dynamic storage pool, or delta replica storage pool. After a volume, dynamic storage pool or delta replica storage pool is created, the raw size of the new volume or the actual raw size allocated to the dynamic storage pool or delta replica storage pool is subtracted from the RemainingManagedSpace of the parent concrete pool.
