NetWare 6.5 requires a minimum of 512 MB of RAM and can access up to 64 GB of RAM. After the server.exe file is loaded, the remaining memory below 4 GB is assigned to cache memory and virtual memory, which is available for NetWare Loadable Module™ (NLM™) programs and other processes to use.
NOTE:The maximum memory that your server requires depends on the products and components that you install on your server and the number of applications that you run on your server that use protected memory.
The memory allocator cannot allocate memory above 4 GB. If you install more than 4 GB, this memory is used by the virtual memory system, NSS, and applications such as eDirectory™. The Traditional file system does not use memory above 4 GB.
The applications that run in the memory above 4 GB leave more memory below 4 GB for the memory allocator to use. So, although you cannot configure the memory above 4 GB, adding more memory has the following performance advantages:
More memory is available to those systems and applications that run in protected memory or in the space above 4 GB.
The more available memory below 4 GB the memory allocator has to use, then the faster the server performs.
