Installing The Basic Cluster Hardware; Terminal Server - Red Hat CLUSTER SUITE - CONFIGURING AND MANAGING A CLUSTER 2006 Manual

Chapter 2. Hardware Installation and Operating System Configuration
optional console switch and network switch or hub. Follow these steps:
1. In all nodes, install the required network adapters and host bus adapters. Refer to
Section 2.3.1 Installing the Basic Cluster Hardware for more information about per-
forming this task.
2. Set up the optional console switch and connect it to each node. Refer to Section 2.3.3
Setting Up a Console Switch for more information about performing this task.
If a console switch is not used, then connect each node to a console terminal.
3. Set up the network switch or hub and use network cables to connect it to the nodes
and the terminal server (if applicable). Refer to Section 2.3.4 Setting Up a Network
Switch or Hub for more information about performing this task.
After performing the previous tasks, install Red Hat Enterprise Linux as described in Sec-
tion 2.4 Installing and Configuring Red Hat Enterprise Linux.

2.3.1. Installing the Basic Cluster Hardware

Nodes must provide the CPU processing power and memory required by applications.
In addition, nodes must be able to accommodate the SCSI or Fibre Channel adapters, net-
work interfaces, and serial ports that the hardware configuration requires. Systems have a
limited number of pre-installed serial and network ports and PCI expansion slots. Table
2-10 helps determine how much capacity the employed node systems require.
