While operating systems may support eight-way or larger systems, scalability is a function of both the operating system and the application/workload. Few applications are designed to take advantage of larger SMP systems. 2. x440 configurations with 16 processors and Hyper-Threading enabled are seen as 32 processors under Windows 2000 Datacenter and Windows .NET. Licensing of processors in Windows 2000 is based on physical and logical processors combined, whereas Windows .NET licensing is based on physical processors. 3. NetWare notes: - NetWare 5.1 is currently not supported, but it should still install.
