The appropriate NetApp feature to use in this scenario is aCloud Storage Pool. A Cloud Storage Pool in NetApp StorageGRID allows the administrator to tier data to public clouds like Amazon S3 Glacier Deep Archive. This feature lets the administrator keep local replicated copies for performance, geo-dispersederasure-coded copies for durability, and tier cold or backup data to Glacier for long-term retention and cost savings.

FabricPool (B)andFlash Pool (C)are not relevant to S3 data tiering and bucket replication in StorageGRID.Dynamic Disk Pool (D)is more applicable to disk management in traditional storage arrays, not for managing S3 bucket replicas across different storage locations.

NetApp Cloud Volumes ONTAP provides a High Availability (HA) configuration, which is crucial for ensuring that services remain available even during unplanned outages. When using NetApp Cloud Volumes ONTAP in environments such as Azure, ensuring continuous availability, especially for NFSv4 workloads, is vital.

The "High Availability" (HA) feature creates a pair of ONTAP instances configured as an active-passive cluster. This setup reduces failover times by allowing one node to take over if the other fails, providing minimal service disruption. HA is designed to manage failovers automatically, which is essential for applications requiring constant availability, such as those using NFSv4. In Azure, enabling this feature via the appropriate subscription registration ensures that when an unexpected failure occurs, the system will automatically failover to the standby node, minimizing downtime and ensuring that the application continues to function smoothly without manual intervention.

In this case, "multipath HA," "fault tolerance," and "redundancy" are related concepts, but they don’t directly address the specific need to register and enable the high-availability feature in Azure. Registering HA on the Azure subscription ensures that the Cloud Volumes ONTAP can perform its failover processes effectively, keeping the application running.

The company is migrating data from a 6-node, on-premises NetApp FAS cluster toNetApp Cloud Volumes ONTAPand determined that they can consolidate to two HA pairs. This means that the minimum number of Cloud Volumes ONTAP instances required is2, as each HA pair corresponds to one instance.

1 instance (A)would not provide the required redundancy and performance, and6 instances (B)or4 instances (D)are unnecessary given the performance sizing results.
