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

 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

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

The Active IQ Web site is a tool that provides insights and recommendations for your NetApp systems based on data collected from AutoSupport. You can use the Active IQ Web site to accomplish the task of locating empty SAS ports remotely by accessing the Inventory page and selecting the HA pair. You can then view the details of each node and see the port utilization and availability for each SAS port. The other tools are not suitable for this task because they do not provide the specific information about the SAS ports of your HA pair. ONTAP System Manager is a web-based interface for managing ONTAP clusters, but it does not show the port utilization and availability for SAS ports. Hardware Universe is a tool that provides information about the compatibility and specifications of NetApp hardware products, but it does not show the port utilization and availability for SAS ports. Interoperability Matrix Tool is a tool that provides information about the supported configurations and software versions for NetApp products, but it does not show the port utilization and availability for SAS ports. References :- Active IQ Web - NetApp, Active IQ Inventory - NetApp, Active IQ Documentation - NetApp
