Use Jetstress to verify the performance and stability of a disk subsystem prior to putting an Exchange server into production. Jetstress helps verify disk performance by simulating Exchange disk Input/Output (I/O) load. Specifically, Jetstress simulates the Exchange database and log file loads produced by a specific number of users. You use Performance Monitor, Event Viewer, and ESEUTIL in conjunction with Jetstress to verify that your disk subsystem meets or exceeds the performance criteria you establish. After a successful completion of the Jetstress Disk Performance and Stress Tests in a non-production environment, you will have ensured that your Exchange disk subsystem is adequately sized (in terms of performance criteria you establish) for the user count and user profiles you have established. It is highly recommended that the Jetstress user read through the tool documentation before using the tool.
Note Jetstress is only supported when running with Exchange 2000, Exchange 2003, Exchange 2007 or newer versions of ESE.DLL. Also, due to this support limitation, Jetstress is only supported on Windows 2000 Server, Windows Server 2003, Advanced Server, Datacenter and newer Windows OS platforms (Windows NT 4.0 and older builds are not supported).
