Smart Flash Cache and Smart Flash Logging

  • John Clarke

Abstract

Smart Flash Cache and Smart Flash Logging make the Exadata Database Machine the first flash-optimized Oracle database platform by providing intelligent caching algorithms to cache “appropriate” data in flash-based storage. Exadata’s use of flash storage is named “smart” due to the intelligence of Oracle’s caching algorithms. The Exadata storage cell software automatically and intelligently determines which data to cache on the storage cell flash cards based on the nature of the data being requested. This typically includes frequently accessed data and index blocks, control file reads and writes, file header blocks, and any object the Exadata DMA chooses to cache with use of the flash-based KEEP clause.
