At the heart of every Oracle Exadata Database Machine are Oracle Exadata Storage Servers, which combine smart storage software and industry-standard hardware to deliver the industry's highest database storage performance. To overcome the limitations of conventional storage, Oracle Exadata Storage Servers use 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. The result is faster parallel data processing and less data movement through higher bandwidth connections. This massively parallel architecture also offers linear scalability and mission-critical reliability. We will be looking at the architecture of EXADATA machine (The world's fastest OLTP machine) from a performance perspective.
