The store process controller monitors the health of all store worker processes on the server. When a database is dismounted, the worker process for that database is terminated.įor example, if you have 40 mailbox databases mounted on a Mailbox server, there will be 41 processes running for the Managed Store: one for each database, and one for the store service process controller. When a database is mounted, a new worker process is instantiated that services only that database. One worker process for each mounted database (.exe). The multi-process model that's used by the Managed Store consists of the following processes on the Mailbox server:Ī single store service controller process for the whole Exchange server (.exe, also known as MSExchangeIS). The Managed Store also uses a static database caching mechanism that replaces the dynamic buffer algorithm in previous versions of Exchange. Introduced in Exchange Server 2013, the Managed Store uses a controller/worker process model that provides storage process isolation and faster database failover.
