2.4 Cabling for the Console Network

The console network is part of the private administration network within an HP XC system, and it is used primarily for managing and monitoring the node consoles.

On a small cluster, the console management devices can share a single top-level ProCurve 2800 root administration switch. On larger hardware configurations that require more ports, the console network is formed with separate ProCurve model 2600 series switches.

You arrange these switches in a hierarchy similar to the administration network. One switch is designated as the root console switch and that switch can be connected to multiple branch console switches. The top-level root console switch is then connected to the root administration switch.

HP server blades use iLO2 as the console management device. Each iLO2 in an enclosure connects to the Onboard Administrator. To form the console network, connect the Onboard Administrator of each enclosure to one of the ProCurve console switches.

Non-blade server nodes must also be connected to the console network. See Chapter 3 (page 45) to determine which port on the node is used for the console network; the port you use depends on your particular hardware model.

Figure 2-5illustrates the connections that form the console network.
