Storage Consolidation
Mail Server Clustering

For mission-critical reliability and increased scalability, you can cluster multiple mail servers using Xsan 2 as the back-end data store. This ensures reliable data access for all servers in the cluster and makes it easy to scale your mail server infrastructure to handle increasing loads.
Mail server clusters are typically made up of three or more servers: at least one for Xsan and two or more for mail services. Each cluster member, or node, runs a copy of Xsan and is configured to have direct Fibre Channel access to RAID storage. In this way, each node has direct block-level access to the same shared data store.
In the event of a server failure, mail clients can reconnect automatically to a remaining server in the cluster. If the failed server was in the middle of processing an SMTP spool file, another node in the cluster takes over the processing of its spool file. Although this response is automatic, you will see it noted in the mail service log files.
