Network Topology: Hybrid Setup

Note

The following diagram is for representational purposes only.

In a Hybrid Setup, the OIM and special nodes such as the head and login node are connected to the public network, while the iDRAC and the compute nodes use a shared LOM network.

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

• Admin Network and BMC network (Green line): This indicates the admin network and the BMC network utilized by Omnia to provision the cluster nodes and to control the cluster nodes using out-of-band management. NIC1 of all the nodes are connected to the private switch.

• Infiniband Network (Yellow Line): This indicates the high-speed InfiniBand network used for high throughput inter-node communication in the cluster.

Note

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

Recommended discovery mechanism

• Discovery Mechanisms (OME-based BMC Discovery is recommended)
