The Fault-tolerant GridServer Deployment

A DataSynapse GridServer deployment consists of a Primary Director, an optional Secondary Director, and one or more Brokers. Drivers and Engines log in to the Director, which routes them to one of the Brokers. Directors balance the load among their Brokers by routing Drivers and Engines to currently running Brokers.

A minimal fault-tolerant GridServer deployment contains two Directors, a Primary and a Secondary, and at least two Brokers. The Brokers, Engines, and Drivers in the grid have the network locations of both the Primary and the Secondary Directors. During normal operation, the Engines and Drivers log in to their Primary Director; the Secondary Director is completely idle.

Other GridServer topographies, such as having multiple Managers to handle volume or to segregate different types of Services to different Managers, are discussed in the GridServer Installation.
