Cabling Your Blade Cluster

Hardware

NOTE: The cluster nodes represent the individual server modules in your Dell™

PowerEdge™ server enclosure. The designations namely, node 1 and node 2 and

the server enclosure are used for illustrative purposes only. The system and the

storage components in your cluster configuration may vary.

Cabling Your Cluster For Public and Private

Networks

The network interface cards (NICs) in the cluster nodes provide at least two

network connections for each node, as described in Table 2-1.

Figure 2-1 shows an example of network connection for a PowerEdge M1000e

server enclosure in which dedicated NICs in each server module are internally

connected to each other through an Ethernet switch module (for the private

network) and the remaining NICs are connected to the public network.
