Network and switch requirements

The switches you use for NetApp HCI require specific configuration to ensure a successful deployment. See your switch documentation for specific instructions on implementing each of the following requirements for your environment.

NetApp HCI deployment requires at least three network segments, one for each of the following types of traffic: Depending on the NetApp H-Series compute and storage node models and the planned cabling configuration, you can physically separate these networks using separate switches or logically separate them using VLANs. For most deployments, however, you need to logically separate these networks (and any other additional virtual machine networks) using VLANs.

Compute and storage nodes need to be able to communicate before, during, and after deployment. If you are implementing separate management networks for storage and compute nodes, ensure that these management networks have network routes between them. These networks must have gateways assigned, and there must be a route between the gateways. Ensure that each new node has a gateway assigned to facilitate communication between nodes and management networks.

NetApp HCI has the following switch requirements:

All NetApp HCI nodes provide additional out-of-band management capabilities via a dedicated management port. NetApp H300S, H300E, H500S, H500E, H700S, H700E and H410C nodes also allow for IPMI access via Port A. As a best practice, you should ease remote management of NetApp HCI by configuring out-of-band management for all nodes in your environment.

Note: The management network of the management node needs a configuration that includes a gateway address to be able to communicate with NetApp Cloud Services. Enabling NetApp cloud services will fail if a valid gateway address is not in place.
