WebTrends currently does not support Itanium or Itanium 2 processors from Intel. These two processors are true 64-bit processors and do not support the 32-bit instruction set, which means these processors are not backwards-compatible. Operating systems do have a compatibility mode for 32-bit applications, but this is not certified for WebTrends to run on.

Two exceptions to this are AMD 64-bit processors and Intel EM64T. AMD processors are backwards-compatible and the Intel EM64T processor is a 32-bit processor.


Below are the maximum number of processors and amount of memory each OS supports:

OS Processors Memory Platform
Windows Server 2003 Web Edition 2 2 GB x86 (32-bit)
Windows Server 2003 Standard Edition 4 4 GB x86 (32-bit)
Windows Server 2003 Enterprise Edition Edition 8 32 GB x86 (32-bit)
Windows Server 2003 Datacenter Edition 32 64 GB x86 (32-bit)
Windows Server 2003 Standard x64 Edition 4 32 GB x64 (64-bit)
Windows Server 2003 Enterprise x64 Edition 8 1 TB x64 (64-bit)
Windows Server 2003 Datacenter x64 Edition 64 1 TB x64 (64-bit)
Windows Server 2003 Enterprise 64-Bit Edition 8 1 TB Itanium (64-bit)
Windows Server 2003 Datacenter 64-Bit Edition 64 1 TB Itanium (64-bit)

The x64 versions of 2003 support up to 4GB of memory per process, however WebTrends will only use 3GB per analysis.

If WebTrends is configured to have two concurrent tasks enabled and only 5GB of system memory, it is possible for WebTrends to exceed 5GB memory usage and cause analysis failure. As a result, this may cause stability issues with WebTrends. As it has not been tested, this is not a supported configuration.
