The space guarantee setting determines how much space is reserved in the aggregate for the volume. A space guarantee of “none” means that no space is reserved for the volume, and the volume can use any available space in the aggregate. This approach to space management is called thin provisioning. This setting would prevent the hosting aggregates from showing a decrease in available space when creating new volumes, as long as the aggregate is not overcommitted. References :- How volume guarantees work with FlexVol volumes, How you set space guarantees for new or existing volumes, What is the impact of changing volume space-guarantee from “volume” to “none”?

 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 performance capacity report shows the current and optimal performance metrics for the CPU resource on each node of the cluster. The current metrics reflect the actual workload on the resource, while the optimal metrics reflect the workload that would result in the best performance. The performance capacity, or headroom, is the difference between the current and optimal metrics. A low or negative headroom indicates that the resource is over utilized and may experience performance degradation. The exhibit shows that both nodes have negative headroom for the CPU resource, which means that the CPU has been over utilized. A storage failover event will cause performance issues, as the surviving node will have to handle the workload of both nodes, which will further reduce the headroom and increase the latency. References :- Identify remaining performance capacity, What is Performance Capacity in ONTAP 9 and Unified Manager?
