Cabling Your Cluster Hardware
The following sections provide information on cabling various components of
your cluster.
Cabling the Mouse, Keyboard, and Monitor
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.
Cabling the Power Supplies
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 illustrates a recommended method 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.
