Example system designs

Omnia can configure systems which use Ethernet or Infiniband-based fabric to connect the compute servers.

Example system configuration with Ethernet fabric

Example system configuration with Infiniband fabric

Network Setup

With Omnia 1.2, only the control plane requires internet access. In such a situation, the network topology would follow the below diagram: Network Connections when only the Control Plane is connected to Internet

If the user would like to have all compute nodes connect to the internet, the following network diagram can be followed. Network Connections when all servers are connected to the internet

Network Topology

Possible network configurations include:

  • A flat topology where all nodes are connected to a switch which includes an uplink to the internet. This requires multiple externally-facing IP addresses
  • A hierarchical topology where compute nodes are connected to a common switch, but the manager node contains a second network connection which is connected to the internet. All outbound/inbound traffic would be routed through the manager node. This requires setting up firewall rules for IP masquerade, see here for an example.
