IBM 440 manual Operating system support

In addition to these functions, the Remote Supervisor Adapter is an integral component of the two-node x440 configurations. With the two-node16-way configuration, the adapters are used in the following way:

￿The adapters in both systems are each assigned an IP address (on the same subnetwork)

￿The adapters are connected via their Ethernet ports, either with a cross-over cable, or on a hub or switch, as shown in Figure 3-6 on page 76.

￿One adapter is configured as the primary, and the other is configured as the secondary.

￿Pressing the power button on either x440 will cause the adapters to power up both nodes.

1.12Operating system support

In line with the overall message of providing application flexibility to meet the varying needs of our enterprise customers, the x440 is optimized for numerous operating system and application solutions. Table 1-3on page 29 lists the supported operating systems for the x440. For the latest operating system support information, go to:

http://www.pc.ibm.com/us/compat/nos/matrix.shtml

See 3.5, “Operating system considerations” on page 90 for further information on operating system support on the x440.

Note: Windows 2000 Datacenter Server and VMware ESX Server are the only operating systems currently supported on the 16-way x440 fixed configuration.

In the column titled Hyper-Threading Support in Table 1-3 on page 29:

￿None indicates the operating system does not recognize the logical processors that Hyper-Threading enables.

￿Yes indicates that the operating system recognizes the logical processors and can execute threads on them but is not optimized for Hyper-Threading.

￿Optimized indicates that the operating system recognizes the logical processors and the operating system code has been designed to fully take advantage of the technology.
