IBM has announced that users can take "test drives" of its new database management system (DBMS), known as DB2. The newest release of DB2, code-named "Viper," claims to deliver new storage benefits, as well as greater efficiency in database queries.

IBM is pushing two new storage-centric features with the new version of DB2, called cache hinting and I/O prioritizing, both of which improve response time between back-end storage and the database server. Cache hinting tells the storage what frequently accessed data to keep in cache, and I/O prioritizing tells the storage what to send back first.
