Abstract
Herein is an accelerated interface between a database server and a storage area network (SAN). Persistent storage being managed for a database is spread across a number of storage buckets. Global distributed storage metadata is used only for tracking the location of storage buckets on different storage servers. With this approach, a very small amount of memory is needed at a global distributed level to maintain the map. Each storage bucket can have any number of mirrored replicas for further increasing speed and reliability. A database server contains a storage bucket map in memory, and uses the map to do database online transaction processing (OLTP) I/O and smart (i.e. offloaded) database operations on storage. This allows for direct I/O between database server and storage server with lower latency and without using slow and remote middleware such as a logical unit number (LUN) metadata server on a separate network element.
