Dedicated management network
The dedicated management network configuration consists of two distinct networks. One network
carries the cluster and user network traffic. A separate network is dedicated to the management
network traffic. The dedicated management network is equivalent to the standard IBRIX X9720
configuration, which shipped with dedicated switches for the management network.
Motivation
Benefits of the dedicated management network:
• Optimal segregation of the user/cluster traffic and Management traffic.
• Better utilization of customer network infrastructure if there is already a network separation
between management and data traffic.
Reasons to choose a different configuration:
• Increased cabling required for a minimal configuration.
• Less flexibility without physical network changes.
• More effort for the customer to ensure the network is configured correctly.
Logical description
The dedicated management network configuration logically is two separate IP networks with one
network for the user/cluster traffic and a separate network for the management traffic. In this
configuration, the nodes are equipped with two separate bonds: bond0 provides a direct connection
to the management network, and bond1 provides the connection to the user/cluster network.
In Figure 12 (page 39), the sample IP addresses illustrate the relationship between components
and subnets. The subnet mask and IP address assignments in the figure are for illustration purposes
only; customer address allocation schemes can be done differently.
