Network Topology: Dedicated Setup

Note

The following diagram is for representational purposes only.

In a Dedicated Setup, all the cluster nodes (Head, Compute, and Login [optional]) have dedicated iDRAC connections.

  • Public Network (Blue line): This indicates the external public network that is connected to the internet. NIC2 of the OIM, Service cluster nodes, Head node, Service Kubernetes node, and Login node [optional] are connected to the public network.

  • BMC Network (Red line): This indicates the private BMC (iDRAC) network used by the OIM to control the cluster nodes using out-of-band management.

  • Admin Network (Green line): This indicates the admin network used by Omnia to provision the cluster nodes. NIC1 of all the nodes are connected to the private switch.

Note

Omnia supports classless IP addressing, which allows the Admin network, BMC network, Public network, and the Additional network to be assigned different subnets.
