Typically I/O is the bottleneck for Data Warehouses and OLTP systems alike.

Exadata machine smashes through the I/O barrier.

And here is how:

1. Exadata Smart Flash Cache

� Up to 100X faster than disk

� 1 million I/O’s per second

� 5 Terabytes of flash per storage server

� Intelligently managed flash

� Assign tables to flash storage via SQL statements

2. Exadata Intelligent Storage

• Data intensive processing moved to Storage Grid

• Up to 10X less data sent to Database servers


Exadata


And here is how continued:

3. Exadata Hybrid Columnar Compression

� Column based organization and compression

� A 10X compression ratio typically achieved

� 15X to 50X archival mode compression

� Benefit from faster I/O, cache, backups, DR, Clone, Reorg

� Massive disk storage reduction

4. Exadata Storage Index

� In-memory storage indexes

� Maintains summary information about table data (column MIN and MAX values)

5. InfiniBand Network

• High-speed interconnect architecture - low latency and high throughput

• Unified server and storage network

• RAC interconnect over InfiniBand


Extreme Performance

� tpmC – 30 million transactions per minute.

� 43 Trillion transactions per day (0.5 second average response time).

� Up to 50,000 Disk IOPS (I/O’s per second).

� Up to 1,500,000 Flash IOPS.

� 12X faster for Internet apps, to over 1 Million HTTP requests per second.

� 4.5X faster for Java messaging apps, to over 1.8 Million messages per

second.

� 4X to 50X compression ratio delivered.

� Up to 75 GB per second of raw I/O bandwidth.

� 10X to 50X query performance improvement for Data Warehouses.

� Up to 12 TB/Hour data load rate.

� Near zero encryption overhead for hundreds of Gigabytes per second

transfer.

Significant reduction in Total Cost of Ownership

� Eliminates vendor integration and component regression testing.

� One Patch for software, hardware, firmware.

� One Vendor – Hardware & Software perfectly compatible and tuned.

� One Vendor implementation - No teams from multiple vendors.

� Reduced capital investment through consolidation (OLTP, DW and mixed

work loads on same systems).

� Pre-packaged, pre-configured and pre-optimized.

� Building block scalability by just connecting cables.

� Reduced change management risk.

Exadata
