HDI – Hitachi Data Ingestor

Hitachi Dynamic Tiering (HDT) simplifies storage administration by automatically optimizing data placement in 1, 2 or 3 tiers of storage that can be defined and used within a single virtual volume. Tiers of storage can be made up of internal or external (virtualized) storage, and use of HDT can lower capital costs

ZPR - Zero Page Reclaim

Zero Page Reclaim facility examines the volumes of physical capacity on a Hitachi Universal Storage Platform® and where the firmware determines that no data other than zeros is found on a Dynamic Provisioning software pool page, the physical storage is unmapped and 'returned' to the pool's free capacity.
