Chapter 1. Technical description 29
Table 1-3 x440 operating system support
Notes to Table 1-3:
1. 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. See
RETAIN tip H176163 for details on a known shutdown problem:
