Adaptive Data Reduction in the Hitachi Storage Virtualization Operating System Pattern Detection a

Adaptive Data Reduction technology in Hitachi Storage Virtualization Operating System (SVOS) delivers lower cost and capacity savings. Pattern detection and removal scans incoming data, looking for duplicate 8kB chunks that meet predefined patterns, and they are never written. Instead, a small amount of metadata is created. This provides capacity savings since data that matches one of the predefined patterns does not need to be stored. Pattern detection and removal also avoids a write operation, which thereby prolongs flash media life .
