A quick note to inform you the the JetStress tool has been updated to version 14.1.225.17.

The online documentation on TechNet is currently being revised (article 706601). Currently on the following sentence has been removed from the article:

“You should test Jetstress 2010 with Exchange 2010 ESE binaries, and use Jetstress 2007 for testing legacy ESE versions of Exchange 2007 and Exchange 2003”

The JetStress tool can be used to simulate disk I/O load on a test server running Exchange to test and validate performance and stability of the disk subsystem, prior to moving them into a production environment.

The toolkit page has been updated accordingly.

You can download it here; x86 version is located here.
