In a Sangfor HCI 2-node deployment without a switch, you can use a direct-connect topology. Here's a recommended approach:

Connect the two HCI nodes directly: Use Ethernet cables to establish connections between the two HCI nodes. Each node should have multiple Ethernet ports, so you can use them for inter-node communication.

Configure network settings: Assign IP addresses to the Ethernet ports on each node. Make sure they are on the same subnet and can communicate with each other.

Set up a dedicated storage network: Since HCI involves shared storage, it's recommended to have a dedicated network for storage traffic. Create a separate network or VLAN on the available Ethernet ports of both nodes for storage communication.

Configure network teaming/bonding: Use network teaming or bonding to aggregate multiple Ethernet ports for increased bandwidth and redundancy. Sangfor HCI typically supports link aggregation techniques such as LACP (Link Aggregation Control Protocol) or static link aggregation. Configure this on both nodes to maximize network performance.
Configure network redundancy: Implement redundancy to ensure high availability. You can utilize features like NIC teaming, failover clustering, or Sangfor HCI's built-in redundancy mechanisms to create redundant paths for network traffic.

Verify connectivity and test performance: Once the network configuration is complete, test the connectivity between the two HCI nodes. Ping each node from the other to ensure they can communicate successfully. Additionally, perform performance tests to validate the network's stability and throughput.

Also, it's important to consult Sangfor HCI's documentation or reach out to their support for specific configuration details and best practices based on your environment and requirements.
