ONTAP Select - Host w/ 2x 25GbE ports

pedro_rocha — Tue, 16 Jul 2024 13:52:34 GMT

Hello!

ONTAP Select docs (https://docs.netapp.com/us-en/ontap-select/concept_nw_vsphere_vswitch_config.html) states that for a deployment of a 2-node OTS cluster in 25GbE 2-port hosts.. we should use active-active NIC teaming:

But also, there's a table describing active/standby teaming:

So, I guess we should use active/standby and the above picture is wrong (active-active should be replaced by active-standy). Does it make sense?

Kind regards,

Pedro

I understand that this can be confusing and I would agree that "Active-Active NIC teaming" is not the best wording, though it is still Active-Active.

Essentially both NICs on the ESXi host are active:

vmnic0 is active for External 1 and Internal 1, but is standby for Internal 2 and External 2
vmnic1 is active for Internal 2 and External 2, but is standby for External 1 and Internal 1.

There is not an active/active LAG/Bond/LACP group.

Hello!

Problem is that it is possible to set the portgroup as active-active (without using LAG/Bond/LACP).

That drawing is misleading the reader as the table is pretty straightforward that the recommendation is active-standby.

For a given portgroup the configuration is active-standby. From the ESXi host perspective, all the NICs are active.
