Oracle Exadata is a database device that combines the properties and strengths of computation, storage, and networking in one portfolio. It works on RAC infrastructure and employs advanced features like hybrid columnar compression, smart flash cache, intelligent storage and storage indexes for tremendous performance. Exadata machine is of two types, X3-2 and X3-8. These differ in what is known as the system capacity and also configurations. Moreover, Exadata machines can be quarter rack, half rack or full rack. Exadata machines are useful in OLTP (Online transaction processing) environments where the database layer should be highly optimized with extremely efficient performance.
Database Machine and Exadata storage delivers advanced analytic as well as I/O performance, is simple to use and maintain, and delivers mission-critical availability and reliability. Another integral part of Exadata Database Machine is The Exadata Storage Server. Extreme performance is promised and delivered by several one in a million features of this product. Exadata storage is responsible for providing database aware storage services, like offloading database processing from the database server to storage, and this is done while being completely transparent to SQL processing and database applications. Hence just the data requested by the application is returned rather than all the data in the queried tables. Exadata Smart Flash Cache dramatically accelerates Oracle Database processing by speeding I/O operations. The Flash provides intelligent caching of database objects to avoid physical I/O operations and speeds database logging. The Oracle Database on the Database Machine is the first Flash enabled database. Exadata storage provides an advanced compression technology, Hybrid Columnar Compression, that typically provides 10x, and higher, levels of data compression. Exadata compression boosts the effective data transfer by an order of magnitude. The Oracle Exadata Database Machine is the world’s most secure database machine. Building on the superior security capabilities of the Oracle Database, the Exadata storage provides the ability to query fully encrypted databases with near zero overhead at hundreds of gigabytes per second. The combination of these, and many other, features of the product are the basis of the outstanding performance of the Exadata Database Machine.
Database management and storage needs an edge where your personal knowledge and application is concerned. And that is the sole reason why Oracle exadata should be something you are very well acquainted with.
