Network Topology: LAN on motherboard (LOM) Setup

A LOM port could be shared with the host operating system production traffic. Also, LOM ports can be dedicated for server management. For example, with a four-port LOM adapter, LOM ports one and two could be used for production data while three and four could be used for iDRAC, VNC, RDP, or other operating system-based management data.

In a shared LOM Setup, the entire cluster network is shared between the iDRAC and the cluster nodes.

  • Public Network (Blue line): This indicates that only the control plane and login node is connected to the external public network.

  • Cluster Network (Green line): This indicates the admin network utilized by Omnia to provision all the cluster nodes (login, head, and compute).

  • IB Network (Yellow line): The network used by the applications on the head and compute nodes to communicate among each other.
