Microsoft has just released the Exchange Server 2010 version of some of the performance tools that should be used during the planning phase of a new mailbox server:
- Microsoft Exchange Server Jetstress 2010 Beta (64 bit) – Use Jetstress 2010 Beta to verify the performance and stability of a disk subsystem prior to putting an Exchange 2010 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 2010 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.
This version is intended for Microsoft Exchange 2010 servers. The I/O profile is still subject to change until official release of Microsoft Exchange 2010 Server. Future versions will provide compatibility with Microsoft Exchange 2007.
- Exchange Load Generator 2010 Beta (64 bit) / (32 bit) – Use Microsoft Exchange Load Generator 2010 Beta (LoadGen) as a simulation tool to measure the impact of MAPI, OWA, ActiveSync, IMAP, POP and SMTP clients on Exchange 2010 servers. LoadGen allows you to test how a server running Exchange 2010 responds to e-mail loads. To simulate the delivery of these messaging requests, you run LoadGen tests on client computers. These tests send multiple messaging requests to the Exchange 2010 server, thereby causing a mail load. LoadGen is a useful tool for administrators who are sizing servers and validating a deployment plan. Specifically, LoadGen helps you determine if each of your servers can handle the load to which they are intended to carry. Another use for LoadGen is to help validate the overall solution.
This version is intended for Microsoft Exchange 2010 Servers only. Future versions will provide compatibility with Microsoft Exchange 2007.
Important! LoadGen should be used only in laboratories that have no connection to the production environment. This tool should not be used in any way in a production environment or an environment that is mission critical or contains important information of any kind anywhere in the network.
Note: The XML configuration file schema in this release has changed from previous versions. You will need to create a new XML configuration file with the Load Generator UI. The existing topology will be marked as un-editable if there are users created by previous versions of Microsoft Exchange Load Generator. Add your remote client machines again, and then save the updated configuration XML.
