Oracle Exadata

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.

Key benefits of Oracle Exadata:

• Uncompressed user data capacity of up to 7 TB per server when using SATA disks
• Exadata Hybrid Columnar Compression often delivers 10X compression ratios
• Effective data bandwidth with Flash and uncompressed data of up to 3.6 GB/second per server
• Effective data bandwidth with Flash and compressed data of up to 36 GB/second per server
• Software pre-installed

Intelligent Oracle Exadata Storage Server Software enables the Exadata Storage Server to quickly process database queries and return only the relevant rows and columns to the database server. By pushing SQL processing to the Exadata Storage Server all the disks can operate in parallel, reducing database server CPU consumption while using much less bandwidth to move data between storage and database servers. The Exadata Storage Server returns a query result set rather than entire tables, eliminates network bottlenecks, and frees up database server resources. This means users often see a performance increase of 10x when analyzing data.
