Harvest Ontap: Disk Dashboard: question about "Disk Utilization"

Good day all, we are working on Harvest (we've installed NAbox v4.2.0 via OVA) and I find it extremely useful for monitoring and trobleshooting.

In these days it helped us finding the cause of a high latency peak on all (nfs exported) volumes of a Node. It appears clearly the root cause to be a high, sustained, almost fully random and 100% write workload that saturates the capacity of the SATA disks of the aggregate.

I would like to have an help about this screeshot from the dashboard in the subject:

the time range is when the issue occurred. The red bar is pretty explicit 😀

I would like to focus on the meaning of the numeric metric: does "Max IOPs" means "the max number of IOPs per single disk"? Or?

Thank you in advance.
