Topic: Cross Platform DB2 for z/OS & LUW
IBM DB2 Analytics Accelerator new release (V3) introduces the High Performance Storage Saver (HPSS) as a new product feature. HPSS provides high-capacity storage with much lower per unit cost than System z. With HPSS the archived tables or partitions can only exist in the accelerator.

At the same time, transparent SQL access to the moved data is provided by the accelerator with exceptionally good performance.
