NVMe load balancing between nodes

Hi,

 

we have a 2-node AFF-A250 running ontap 9.14.1. I'm experimenting with NVMe over TCP and have a question:

 

how can you load balance namespaces between the 2 nodes? When creating a namespace it's creates the volume automatically and chooses the aggregate by itself. How can you ensure that the NVMe namespace load is evenly distributed between the 2 nodes in the cluster?

Hi,

 

I have 4 lifs. 2 lifs per node for NVMe. Those were created after entering the 4 IP addresses when creating the SVM.

That still fits within limitations described in that limitation, IMO.

 

*Within* a node load balancing to the same volume may be possible and happening (I haven't used NVMe/TCP, so I don't know for sure), but that wouldn't be your ask which is load-balancing to the same namespace *across* different nodes.
