Looking at the Cluster Components, the two main CPU resources are: If these two components make up the majority of your latency, then CPU is the primary factor in overall latency. In most AFF systems, CPU is the primary contributor to latency. It would be a 'problem' only if the latency seen is higher than expected. As with UM, if these two components comprise the majority of latency, then CPU is the primary factor in overall latency

There are several scenarios where this may be helpful: Tracking down a volume with high tiering (read/write) activity to the capacity tier "StorageGRID" in performance investigations. Tracking down ONTAP Volume(s) during investigation of lost or quanrantined S3 objects in StorageGRID.
