Network configuration and cabling options

You can use a two-cable network configuration for NetApp HCI compute nodes, simplifying cable routing. This configuration uses two SFP+/SFP28 cables plus an optional (but recommended) RJ45 cable for IPMI communication. Storage nodes support a single network topology that uses four network cables.

All storage nodes support a network topology that uses four network ports; this topology uses ports A through D on H300S, H500S H700S, and 610S nodes. Compute nodes support three network topologies:

Configuration option Cabling and description
Option A Two-cable configuration using ports D and E (two SFP28/SFP+ interfaces) on H300E, H500E, H700E and H410C nodes
Option B Six-cable configuration using ports A through F (two RJ45 and four SFP28/SFP+ interfaces) on H300E, H500E, H700E and H410C nodes
Option C Cable configuration similar to option B, but using native VLANs for the management, storage, and vMotion networks

Nodes that do not have the correct number of connected cables cannot participate in the deployment. For example, you cannot deploy a compute node in a six-cable configuration if it only has ports D and E connected.

Note: You can adjust the NetApp HCI network configuration after deployment to meet infrastructure needs. However, when you expand NetApp HCI resources, remember that new nodes must have the same cable configuration as the existing compute and storage nodes.
