The Heart of Exchange: Exchange Store Technology

This chapter illustrates the exchange database technology regarding the need for high availability for Exchange that should be on the database engine, storage, and data recovery. At the core of every Exchange server lays the Information Store. Implemented in a single process (STORE.EXE), the Exchange Information Store is actually two key components that provide data storage. Microsoft designed Exchange Server to be a highly reliable messaging server platform that would provide continuous operation, high transactional throughput, rapid recovery, and the full operational and functional capability of a relational database system. The Extensible Storage Engine (ESE) supports two core database files for Exchange 2000/2003—the property store and the streaming store. The Exchange server relies on an embedded database engine that lays out the structure of the disk for Exchange and manages memory.
