Oracle

Exadata Hybrid Columnar Compression

The Sun Oracle Database Machine delivers extreme performance and scalability for all database applications including Online Transaction Processing (OLTP), Data Warehousing (DW) and consolidation of mixed database workloads. One of the key enablers of this is the Exadata Smart Flash Cache and the intelligent Oracle Exadata Storage Server Software that drives it. Exadata Smart Flash Cache intelligently caches data from the Oracle Database replacing slow mechanical I/O operations to disk with very rapid flash memory operations. Exadata Smart Flash Cache is the fundamental technology of the Sun Oracle Database Machine Full Rack that enables the processing of up to 1 million random I/O operations per second (IOPS), and the scanning of data within Exadata storage at up to 50 GB/second.
