Recommended Disk Configuration

Before you install Microsoft Exchange Server and run the Performance Optimizer, optimize your disk subsystem. The following is the recommended disk configuration for a Microsoft Exchange Server computer:

• A physical disk containing the operating system and the page file.
• A physical disk for the transaction log files so that they can be written to sequentially. To increase fault tolerance, you can mirror the disk containing the transaction log files.
• A stripe set consisting of multiple physical disks for all other Microsoft Exchange Server components so that the Microsoft Exchange Server databases can be accessed most efficiently.
