Because Microsoft Exchange Server is such a disk-intensive application, it's important to make sure that the disk subsystem can keep pace with its demand.
In this guide, I discuss the various components that can cause disk I/Os on an Exchange server -- Exchange databases and transaction logs, MTA and SMTP queues, Windows pagefiles, indexing, and deleted Exchange database pages -- and how those components should be set up to optimize Exchange Server performance and prevent disk I/O bottlenecks.
Note: This tutorial assumes that you are trying to optimize disk resources for an Exchange server containing mailboxes and/or public folders. Some suggestions I make are not sensible for front-end Exchange servers or servers that do not routinely handle a heavy workload.
