2.1.4 Cluster Hardware Tables
Use the following tables to identify the hardware components required for your cluster configuration.
In some cases, the tables list specific products that have been tested in a cluster, although a cluster is
expected to work with other products.
The complete set of qualified cluster hardware components change over time. Consequently, the table
below may be incomplete. For the most up-do-date itemization of supported hardware components,
refer to the Red Hat documentation website at http://www.redhat.com/docs.

Red Hat Cluster Manager supports IA-32
hardware platforms. Each cluster system
must provide enough PCI slots, network
slots, and serial ports for the cluster hardware
configuration. Because disk devices must have
the same name on each cluster system, it is
recommended that the systems have symmetric
I/O subsystems. In addition, it is recommended
that each system have a minimum of 450
MHz CPU speed and 256 MB of memory.
See Section 2.2.1, Installing the Basic System
Hardware for more information.

Table 2–4, Power Switch Hardware Table includes several different types of power switches. A single
cluster requires only one type of power switch shown below.
