The main Exchange service that takes up memory is store.exe which deals with the core Exchange database services and MAPI access.

Windows 2000/3 Advanced Server and Datacenter Editions also provide the /PAE switch which provides a special API that allows programs to your memory above 4GB. Typically, ISPs and large organizations will need to use this. You should use this if you have a large amount of users. Windows 2003 provides the /USERVA=3030 switch that is used in conjunction with the /3GB switch to allocate 42MB of memory to the kernel for dynamically allocating memory back to the kernel mode in case of need.

This means that a Windows 2000 Server with Exchange 2000/3 installed will not work well with more than 1GB physical memory and in some cases may cause some problems with 1GB if the server is really overloaded.įollowing this logic, this sets the limit of the memory you can allocate for Exchange servers to no more than 3GB unless you do some more tweaking. Multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Windows Server 2003″ /fastdetect /3GB

It takes 1GB off the system allocated space so the User mode (application) virtual address space grows to 3GB.Īfter editing the boot.ini file it should look like this:ĭefault=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS To solve this Microsoft provides the /3GB boot.ini switch which is available for Windows 2000 Advanced and Datacenter version and all Windows 2003 versions.

This is fine for desktops where a lot of graphic work is done by the operating system, but for client server applications such as Exchange, which gobbles up memory, 2GB of virtual memory (that is physical RAM plus page file disk based memory) might not be enough. Windows NT based operating systems allocate 2GB for the operating system and 2GB for applications such as Exchange.

Large operations should definitely upgrade to Windows 2003 and Exchange 2003 to enjoy their improved memory usage and go with 4GB, for a server with a few databases. However some servers with no gateway server filtering out viruses and spam, and users that use Exchange mail with large attachments on a regular basis might find that 1GB is not enough. Allocation of memory depends on the number of users, the size of their mailboxes and the amount of mail that is stored every day.Īn Exchange 2003 server serving 10 users or less can do with 512MB of RAM.Įxchange 2003 servers with standard edition installed should not require more than 1GB of RAM due to the 16GB Information Store limitation. How much memory should I be using?Įxchange is a big memory hog. I use this term loosely because until PCs move to 64-bit and other technologies that have been around for other hardware platforms, the memory architecture will be roundabout. Due to the nature of PC architecture some tweaking is required for efficient use of memory, especially when using more than 1GB RAM.
