 According to the NetApp best practices, flow control should be disabled on data network ports and cluster network ports using 10GbE Ethernet. This is because flow control can cause excessive pause frames, xon/xoff frames, or packets being re-queued, which can affect the network performance and TCP throughput. Flow control works at the physical link layer and does not consider the upper level protocols. Therefore, it is recommended to disable flow control end-to-end on both data and cluster network ports for optimal performance. References :- How to modify flow control on cluster port in ONTAP, What are the flow control best practices for Ethernet?, Configure your network for best performance

The space allocation option is a LUN attribute that enables the host to communicate with the storage system about the blocks that are no longer in use by the host file system. When the space allocation option is enabled, the host sends SCSI UNMAP commands to the storage system when files are deleted on the disk. The storage system then reclaims the space from the thin-provisioned LUN and makes it available for other LUNs or volumes. This process is also known as space reclamation or hole punching. If the space allocation option is disabled, the host does not send SCSI UNMAP commands and the storage system does not reclaim the space from the thin-provisioned LUN, resulting in a discrepancy between the host and the storage system. References :- Space reclamation, Enable or disable the space allocation option for a LUN

File System Analytics is a native ONTAP feature that collects and aggregates data in real time, providing detailed information concerning file and directory count, file-age histograms, capacity use, and other parameters1. You can use ONTAP System Manager to visualize the data using industry standard measures such as hot, warm, and cold2. File System Analytics is available on ONTAP 9.8 and later versions3. Quality of Service, Logical Space Reporting, and volume autosizeare not features that report real-time file counts, but rather features that manage performance, efficiency, and capacity of volumes45 . References :- TR-4867: Best Practice Guidelines for ONTAP FIle System Analytics, File System Analytics overview, File System Analytics feature availability, [Quality of Service overview], [Logical space reporting overview], [Volume autosize overview]
