Shattering I/O Bottlenecks
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

Shattering I/O Bottlenecks
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.
