 = Object storage is a type of storage that provides access using Amazon S3 APIs. Object storage stores data as objects, which consist of data and metadata. Object storage is designed for scalability, durability, and cost-effectiveness. Object storage is suitable for storing unstructured data, such as images, videos, documents, and backups. Object storage does not use a hierarchical file system, but rather a flat namespace that allows users to access objects by unique identifiers. References = Working with Amazon S3-Compatible Storage Accounts, Amazon S3 API Reference, Amazon S3 REST API Introduction

 FabricPool is an ONTAP feature that tiers inactive data to an object store such as StorageGRID. StorageGRID uses erasure coding to protect data by slicing an object into data fragments and parity fragments, and spreading them across Storage Nodes. To use erasure coding, the storage pool must include three or more sites, or exactly one site. Two sites are not supported. Therefore, the minimum number of sites required to deploy the StorageGRID solution with FabricPool and erasure coding is three. References = Configuring StorageGRID for FabricPool, What erasure-coding schemes are

Advanced Disk Partitioning (ADP) is a feature that enables ONTAP to partition a disk into multiple logical units and use them for different purposes. ADP has two main benefits for AFF or FAS systems:

• It optimizes storage capacity by reducing the number of disks required for the root aggregates, which store the system and configuration data. By using ADP, the root aggregate can share the same disk with a data aggregate, which stores the user data. This frees up more disks for data aggregates and increases the usable space for data.
• It reduces RAID parity overhead by creating smaller RAID groups with partitions instead of whole disks. This reduces the amount of parity data that needs to be written and read, which improves the performance and efficiency of the system. References = What are the rules for Advanced Disk Partitioning?, Considerations for automatic drive assignment and ADP systems in ONTAP 9.4 and later, NetApp AFF and Advanced Drive Partition v2, part 1
