Oracle Exadata Storage Server
The Database Machine uses the Oracle Exadata Storage Servers
which are highly optimized for use with the Oracle database.
Exadata delivers outstanding I/O and SQL processing performance for
data warehousing applications by leveraging a massively parallel
architecture to enable a dynamic storage grid for Oracle Database
11g deployments.
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.
Exadata Storage Server Technologies
- Exadata Smart Scan processes queries at the storage layer,
returning only relevant rows and columns to the database server. As
a result, much less data travels over fast 40GB InfiniBand
interconnects-dramatically improving the performance and
concurrency of simple and complex queries
- Exadata Smart Flash Cache addresses the disk random I/O
bottleneck problem by transparently caching 'hot' frequently
accessed data to fast solid-state storage. You get ten times faster
I/O response time and use ten times fewer disks
- Exadata Hybrid Columnar Compression can reduce the size of data
warehousing tables by an average of 10 times, and archive tables by
50 times. This offers significant savings on disk space for
primary, standby and backup databases, and will dramatically
improve the performance of data warehousing queries
