Cabling Your Cluster Hardware

The following sections provide information on how to cable various

components of your cluster.

When installing a cluster configuration in a rack, you must include a switch

box to connect the mouse, keyboard, and monitor to the nodes. See the

documentation included with your rack for instructions on cabling each

node's connections to the switch box.

To ensure that the specific power requirements are satisfied, see the

documentation for each component in your cluster solution.

It is recommended that you adhere to the following guidelines to protect your

cluster solution from power-related failures:

•

For nodes with multiple power supplies, plug each power supply into a

separate AC circuit.

•

Use uninterruptible power supplies (UPS).

•

For some environments, consider having backup generators and power

from separate electrical substations.

Figure 2-1 and Figure 2-2 illustrate recommended methods for power cabling

of a cluster solution consisting of two Dell™ PowerEdge™ systems and one

storage system. To ensure redundancy, the primary power supplies of all the

components are grouped onto one or two circuits and the redundant power

supplies are grouped onto a different circuit.
