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

 = 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

BlueXP tiering is a service that extends your data center to the cloud by automatically tiering inactive data from on-premises ONTAP clusters to object storage. This frees valuable space on the cluster for more workloads, without making changes to the application layer. BlueXP tiering can reduce costs in your data center and enables you to switch from a CAPEX model to an OPEX model. BlueXP tiering leverages the capabilities of FabricPool, which is a NetApp Data Fabric technology that enables automated tiering of data to low-cost object storage. Active (hot) data remains on the local tier (on-premises ONTAP aggregates), while inactive (cold) data is moved to the cloud tier — all while preserving ONTAP data efficiencies12. References = Learn about BlueXP tiering, Cloud Tiering: Free up Space on On-Premises Storage Systems
