1. NetApp, Inc. (2022). TR-4571: FabricPool Overview and Implementation Guide.
Section: "FabricPool" (Page 5) states, "FabricPool is a NetApp ONTAP data-tiering technology that enables you to automatically tier cold data from an all-flash (all-SSD) aggregate to a low-cost object storage tier either in a public cloud or on the premises."
Section: "Supported object stores" (Page 6) explicitly lists "NetApp StorageGRID" as a supported on-premises object store.
2. NetApp ONTAP 9.12.1 Documentation. Data tiering with FabricPool.
Section: "Object stores that are supported by FabricPool" lists the supported on-premises object stores, with "NetApp StorageGRID" being the primary NetApp solution. It clearly distinguishes this from public cloud providers like Amazon S3 and Azure Blob.
3. NetApp, Inc. (2023). TR-4598: FabricPool Best Practices.
Section: "Choosing a Cloud Tier" (Page 10) discusses the options for FabricPool targets, including, "On-premises object stores such as NetApp StorageGRID." This confirms StorageGRID as the designated on-premises solution.
