The Customer Focused Teating (CFT) team at HP previously published the Best practices for HP servers and HP StorageWorks EVA8000 in a Microsoft Exchange Server 2007 environment paper, which presented the results of testing a user environment of 5,000 users with both 100-MB and 1-GB mailboxes. This paper builds upon those results by demonstrating the actual effects of a larger enterprise environment of 20,000 users with 1-GB mailboxes.

This paper provides technical information and best practices for sizing and configuring Exchange Server 2007 on HP server blades with HP EVA storage arrays for the 20,000-user environment.
