In one line

Four different file systems share one name. SSD capacity, throughput and IOPS are each their own line item.

What gets missed

Throughput capacity and SSD IOPS are provisioned independently of storage. Once data sits in ONTAP capacity pool or in Lustre or OpenZFS Intelligent-Tiering, every read and write adds a request charge.
