==== Networks ====

Approximate Darwin network architecture (scheme from [[https://docs.clustervision.com/install/preinstall/#network-requirements-and-configuration|trinityX documetation]]):

{{ :cluster_ha.svg |}}

The only differences: Darwin has 1 head node (controller) and the head node is also connected to IB network.

== Ethernet ==
  * **External (Public) Network:** gateway
  * **Cluster %%LAN%%:** internal cluster network for node communication and management
  * **IPMI Network:** dedicated out-of-band management network (Supermicro IPMI interfaces)

== InfiniBand ==
Switch: 36-port Mellanox Technologies Infiniscale-IV. Speed: 40 Gb/s (4xQDR). Used for high-speed, low-latency communication between compute nodes
