The following software must be installed and running on each computer that will run Microsoft Exchange Server software.
For improved performance, you should plan your server's hardware to meet the expected load. The hardware requirements for each computer that will be running Microsoft Exchange Server software are described in the following table. Note that Microsoft Exchange Server can take advantage of advanced hardware, such as multiprocessor computers and caching disk array controllers.
If you install Microsoft Exchange Server on a pair of clustered servers, the processors and amount of RAM must be the same on each server.
|Minimum|| || |
|Intel® Pentium 90 MHz or faster or Digital Alpha 4/275||
At least 250 MB of available disk space for Microsoft Exchange Server after Windows NT Server has been installed
Sufficient disk space for the Windows NT Server page file (50 MB plus the amount of physical RAM)
At least 24 MB
|Recommended|| || |
|Intel Pentium 166 MHz or faster, or Digital Alpha 5/500||
Sufficient disk space for your users'
e-mail and public folder information
Multiple physical drives
At least one striped drive set
Sufficient disk space for the Windows NT Server page file (100 MB plus the amount of physical RAM)
At least 32 MB
(48 MB for RISC-based systems)
Note If you are adding a server to an existing site, verify that there is enough space on the server's hard disk to import the site's directory. To do so, verify the size of the Dir.edb file in the Exchsrvr\Dsadata directory on another server in the site.
