xSeries 440 Planning and Installation Guide
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:
http://www.pc.ibm.com/qtechinfo/MIGR-43679.html
– 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.
3.5.1 Windows 2000 Datacenter Server
Windows 2000 Datacenter Server is a highly scalable network operating system
designed for mission-critical enterprise-wide applications. High-volume online
VMware ESX Server 1.5 Supports up to 16-way
Supports up to one processor per VM
