Abstract

One of the enhancements provided by Exadata is the Smart Scan, a mechanism by which parts of a query can be offloaded, or handed off, to the storage servers for processing. This “divide-and-conquer” approach is one reason Exadata is able to provide such stellar performance. It’s accomplished by the configuration of Exadata, where database servers and storage cells offer computing power and the ability to process queries, owing to the unique storage server software running on the storage cells.
