Exchange Load Generator v.08.02.0045

Microsoft released an updated version of Exchange Load Generator (v.08.02.0045).

Brief Description
Exchange Load Generator is a simulation tool to measure the impact of MAPI, OWA, IMAP, POP and SMTP clients on Exchange servers.

Use Microsoft Exchange Load Generator (LoadGen) as a simulation tool to measure the impact of MAPI, OWA, IMAP, POP and SMTP clients on Exchange servers. LoadGen allows you to test how a server running Exchange 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 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.

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.

Note: If you use the recipient management features of this release to create users or other recipient objects and you have one or more Exchange Server 2007 servers in your test topology, you must run the Load Generator application with user credentials that have permission to manage Exchange recipients. The directory access account specified in the application configuration will not be used for this purpose.
Note: This version includes scripted module functionality which enables load generation for OWA, IMAP, POP, SMTP.

Exchange Server 2007 Protocol Documentation

Following the commitment that Microsoft made in order to open most of its protocols, “so that software developers, business partners and competitors can better interact with these Microsoft products or invent new solutions for customers”, the Exchange Server 2007 Protocol Documentation is now available to download.

The Microsoft Exchange Server 2007 Protocol technical documentation set provides detailed technical specifications for Microsoft protocols and extensions to industry-standard or other published protocols that are implemented and used in Microsoft Exchange Server 2007 to interoperate or communicate natively with Microsoft Office client and other server products.
The documentation set includes a set of companion overview and reference documents that supplement the technical specifications with conceptual background, overviews of inter-protocol relationships and interactions, and technical reference information.

If you can’t spare the extra 45MB, this information is also available online at the MSDN site.

TechNet Magazine – May 2008

The May edition of TechNet Magazine is now available online or, if you prefer, you can download as an  HTML Help .chm file for offline reading.

Looking at the cover, it seems that the main suject this time is about Active Directory and the ways to protect that valuable asset.

Besides some interesting articles about sustainable computing, which will become a regular online column (“go green” is definitely a trend of our days), since AD and Exchange are so related, there is a good collection of articles that I would like to highlight:

Storage Design for Exchange Server 2007

There’s a new technical document from the Microsoft IT Showcase series available, this time the main subject has to do with storage design: Storage Design for Exchange Server 2007 – How Microsoft IT Exceeds High-Availability Targets with Large Mailboxes at Low Costs Based on New Storage Designs.


Executive Summary

More than 18 months after the first Microsoft® Exchange Server 2007 deployment in the corporate messaging environment and more than 12 months after completing the full production rollout across the entire company, the Microsoft Information Technology (Microsoft IT) group is able to report significant benefits such as:

  • Messaging service levels exceeding high-availability targets of 99.99 percent.
  • Cost reductions in excess of $10 million per year.
  • Increased mailbox quotas by up to a factor of 10.
  • Consolidation of the initial Exchange Server 2007 base by nearly a factor of two.

Microsoft IT was able to achieve these results by taking full advantage of new storage features and input/output (I/O) improvements in Exchange Server 2007, the latest advancements in 64-bit processor technology, and direct-attached storage (DAS)–based storage solutions.

TechNet Magazine – March 2008 & April 2008

The RSS feed from TechNet Magazine changed, that’s why I completely missed the March edition. Meanwhile the April edition came out, so you now have twice the reading (and don’t forget the long weekend reading I posted yesterday!).

The March edition was about Windows Server 2008 (no surprise).

Although there aren’t any Exchange related articles, I recommend a thorough reading, since Exchange Server 2007 SP1 and Windows Server 2008 are a perfect match.

As usual, you can download this entire issue as a standalone HTML Help file (.CHM).



The April issue of TechNet Magazine it’s about SQL Server 2008. Again, no surprise, since Microsoft is focusing on the products of the Global Launches: Windows Server 2008, SQL Server 2008 and Visual Studio 2008.

Don’t expect to find any Exchange related articles, besides the usual PowerShell column.

If you prefer to read the magazine offline, download it in the HTML Help file format (.CHM).
