spanning-tree portfast trunk
◦
On Mellanox switches, you can do this with the spanning-tree port type edge command.
• NetApp HCI nodes have redundant ports for all network functions except out-of-band management. For the
best resiliency, divide these ports across two switches with redundant uplinks to either a traditional
hierarchical architecture or a layer 2 spine-and-leaf architecture.
• The switches handling storage, virtual machine, and vMotion traffic must support speeds of at least 10GbE
per port (up to 25GbE per port is supported).
• The switches handling management traffic must support speeds of at least 1GbE per port.
• You must configure jumbo frames on the switch ports handling storage and vMotion traffic. Hosts must be
able to send 9000 byte packets end-to-end for a successful installation.
• Round-trip network latency between all storage and compute nodes should not exceed 2ms.
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.

Network cable requirements
You can use the following guidelines to ensure that you have enough of the right type of
network cables for the size of your deployment. For RJ45 ports, you must use Cat 5e or
Cat 6 rated cables.
• Two-cable compute node configuration: Each compute node must to be connected to a 10/25GbE network
via two SFP+/SFP28 interfaces (one additional Cat 5e/6 cable is optional for out-of-band management).
• Six-cable compute node configuration: Each compute node must to be connected to a 10/25GbE network
via four SFP+/SFP28 interfaces and to a 1/10GbE network via two Cat 5e/6 cables (one additional Cat
5e/6 cable is optional for out-of-band management).
• Each storage node must be connected to a 10/25GbE network via two SFP+/SFP28 interfaces and to a
1/10GbE network via two Cat 5e/6 cables (one additional Cat 5e/6 cable is optional for out-of-band
management).
• Ensure the network cables you use to connect the NetApp HCI system to your network are long enough to
comfortably reach your switches.
For example, a deployment containing four storage nodes and three compute nodes (using the six-cable
configuration) requires the following number of network cables:
• (14) Cat 5e/6 cables with RJ45 connectors (plus seven cables for IPMI traffic, if desired)
• (20) Twinax cables with SFP28/SFP+ connectors
This is due to the following reasons:
