Network configuration is super important for distributed storage. Since data is spread across multiple nodes, a well-configured network is crucial for performance and reliability. You'll need to ensure that all storage nodes are on the same network and can communicate with each other. This often involves setting up a dedicated network for storage traffic, separate from your general network traffic. This dedicated network helps to avoid congestion and ensure consistent performance. IP addresses need to be assigned to each storage node, and these addresses should be static to avoid conflicts. DNS (Domain Name System) should also be configured correctly so that the nodes can resolve each other's hostnames. If you're using multiple network interfaces, you might need to configure bonding or teaming to improve bandwidth and redundancy. This involves combining multiple network interfaces into a single logical interface. VLANs (Virtual LANs) can be used to segment your network and isolate storage traffic. This is especially useful in larger environments. Finally, don't forget about firewalls. You'll need to configure your firewalls to allow the necessary traffic between the storage nodes and the management interface. This involves opening specific ports required by the Huawei storage software.
