Hitachi Command Suite Data Mobility software automates data placement across storage tiers using Hitachi Dynamic Tiering and Hitachi Tiered Storage Manager. Dynamic Tiering uses I/O patterns to automatically move the most active data to the highest performing storage tier, while less frequently accessed data is moved to lower tiers. Tiered Storage Manager allows administrators to define storage tiers and policies to optimize data placement for different business applications. The software simplifies tiered storage management and improves performance and utilization while lowering costs.
