28 IBM ^ xSeries 440 Planning and Installation Guide
In addition to these functions, the Remote Supervisor Adapter is an integral
component of the two-node x440 configurations. With the two-node 16-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.
1.12 Operating 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 1-3 on page 29 lists the
supported operating systems for the x440. For the latest operating system
support information, go to:

See 3.5, “Operating system considerations” on page 90 for further information on
operating system support on the x440.
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.
Note: Windows 2000 Datacenter Server and VMware ESX Server are the only
operating systems currently supported on the 16-way x440 fixed configuration.
