How does Oracle access data stored on the Exabyte storage?
Data on the Exabyte storage is stored in standard ASM disk groups. The data can be accessed using standard block I/O methods (reads and writes to/from the DB Buffer Cache). In addition, queries can be offloaded to the storage devices, which will scan the disks in parallel and only return the required result set (rows and columns). These result sets will be stored in the database’s query cache.
