Notes to Table 3-2:

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:

With NetWare 6.0, the server may show extreme CPU utilization values (for example, 13000%). This will be fixed with NetWare 6.0 Support Pack

2. See RETAIN tip H176060 at:

http://www.pc.ibm.com/qtechinfo/MIGR-43532.html

Once supported a multi-chassis configuration must be fully assembled before installing NetWare. Novell doesn’t currently support adding chassis after NetWare is installed.

4.Ongoing work will improve both Linux and key application scalability. Currently, the general recommendation is to keep system size limited to eight-way and below, and 16 GB and below. Work on scalability beyond eight-way is in progress, and is likely to become available in early to mid-2003.

5.VMware ESX Server 1.5 allows eight virtual machines per processor. However, a virtual machine (VM) can consist of no more than one processor. 16-way support will require Version 1.5.1.
