Performance of Microsoft Exchange
Server 4.0 on Compaq ProLiant Servers
Electronic messaging is consistently becoming more pervasive in the business world. As
people must process increasing amounts of information, there is a need for powerful
software and hardware products to satisfy the requirements imposed.
To fill the need for a powerful messaging software product, Microsoft has created
Microsoft Exchange Server 4.0. This product has been the focal point of extensive
development and testing efforts involving the commitments of both Microsoft and its
partners. During this time, Compaq and Microsoft have worked together to optimize
Microsoft Exchange Server on Compaq System products.
Microsoft Exchange Server is enormously complex, with many features and capabilities.
One important part of understanding the product is understanding its performance. For
system administrators and potential purchasers of both Microsoft Exchange Server and
Compaq products, this aspect of Microsoft Exchange Server is crucial to understand so
the proper decisions can be made.
This white paper covers various performance aspects of Microsoft Exchange Server 4.0
on Compaq ProLiant Servers, specifically the ProLiant 4500 and the ProLiant 5000.
Fundamentally, this paper should provide the reader with an expectation of how
Microsoft Exchange Server will perform on a Compaq ProLiant under various user
loads. Furthermore, the paper should uncover other useful information pertaining to
Microsoft Exchange Server configuration and performance tuning, as well as CPU,
RAM, and disk utilization on Compaq ProLiant servers. Ultimately, this paper should
help the potential purchaser make good decisions about which Compaq products to
purchase in order to satisfy the requirements of his or her business needs.
