NS0-162 Exam Dumps : NetApp Certified Data Administrator (ONTAP)

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]

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

 FabricPool is a feature of ONTAP that allows you to tier cold data from a local tier (aggregate) to a capacity tier (object storage) in the cloud or on-premises. ONTAP 9.8 supports four types of capacity tiers: AWS S3, Azure Blob, Google Cloud Storage, and ONTAP S3. StorageGRID is a NetApp product that provides on-premises S3 object storage. Therefore, both StorageGRID and ONTAP S3 are supported as capacity tiers for FabricPool aggregates in ONTAP 9.8. SWIFT Object Store and NFS Export are not supported as capacity tiers for FabricPool aggregates. References :- Considerations and requirements for using FabricPool, Storage Efficiencies, FabricPool with StorageGRID Recommendation Guide
