IOPS for Deduplication Database Volumes

When you commission disk storage to store deduplication databases (DDBs), plan for and measure the I/O Operations Per Second (IOPS).

DDB disk volume stores a multi-threaded high performance database that contains block signatures. DDB must be on a fast, dedicated disk for optimal backup and DASH copy performance.

After you configure storage volumes, run IOmeter to confirm that the volumes provide the recommended IOPS as described in the Deduplication Building Block Guide. These storage volumes must provide rated IOPS for the DDB to function efficiently.
