Message store high availability
High availability is achieved by failing over messaging engines between servers. Both file stores and data stores can be deployed in a highly available environment.
In this figure, two servers access a message store that is either a file store accessed through a network file system or a data store that is accessed through a remote database server. This means a messaging engine running on one of the servers can be failed over to the other server, and will retain access to the message store.
