Oracle Exadata Storage
Oracle Exadata is a family of high performance storage software and hardware products that can improve data warehouse query performance by a factor of 10X or more. Oracle Exadata Storage is a combination of smart storage software from Oracle and industry-standard hardware from HP. Overcoming the limitations of conventional storage, Oracle Exadata uses a massively parallel architecture to dramatically increase data bandwidth between the database server and storage. In addition, smart storage software offloads data-intensive query processing from Oracle Database 11g Servers and does the query processing closer to the data. The result - faster, parallel data processing and less data movement through higher bandwidth connections.
