Data Warehouse Appliance: Oracle Exadata

Data Warehouse Appliance, Posts Apr 18, 2011 No Comments

Announced by CEO Larry Ellison at the 2008 Oracle OpenWorld conference in San Francisco, Oracle Exadata Database Machine is a complete database appliance with support for both transactional (OLTP) and analytical (OLAP) database systems. Delivered as a complete package of database software, operating system, servers, and storage, the Oracle Exadata Database Machine is simple and fast to implement and ready for large-scale business applications.

The product was initially assembled in collaboration between Oracle Corporation and Hewlett Packard (HP) where Oracle developed the database, operating system and storage software, while HP constructed the hardware.  However, with Oracle’s acquisition of Sun Microsystems, Oracle announced the release of Exadata Version two with improved performance and usage of Sun Microsystems storage and operating systems technologies. The main idea of Exadata is to make the storage database aware and push processing of queries down to the disks for optimal scanning and performance. Subsequently an Exadata machine can scan 1 TB of data in about 3.5 seconds by scanning several (or all) disks in parallel with Oracle’s Parallel Query technology.

Currently the Oracle Exadata Database Machine provides a solution for all types of database systems, ranging from scan-intensive data warehouse applications to highly concurrent transactional applications.  With its bundled combination of storage, database software, operating system, and standard hardware components from Sun, the Oracle Exadata Database Machine provides extreme performance within a highly-available, highly-secure environment. Additionally Oracle’s unique clustering and workload management capabilities position the Oracle Exadata Database Machine to be well-suited for consolidating multiple databases onto a single and centralized environment.
