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

SnapMirror is a native ONTAP feature that enables customers to create a disaster recovery site and host backups for their on-premises NetApp ONTAP based storage systems in a public cloud. SnapMirror provides reliable, bandwidth-efficient data replication and protection across hybrid multicloud environments. SnapMirror can replicate data from on-premises ONTAP systems to cloud-based ONTAP systems such as Cloud Volumes ONTAP or Amazon FSx for NetApp ONTAP. SnapMirror also supports data tiering to cloud object storage using FabricPool. References = SnapMirror technology, NetApp ONTAP, Learn about BlueXP disaster recovery for VMware preview

= Active IQ Unified Manager is a tool that enables you to define the performance and storage objectives for a workload using Performance Service Levels (PSLs). You can assign a PSL to a workload when initially creating the workload, or afterwards by editing the workload. The management and monitoring of storage resources are based on Service Level Objectives (SLOs), which are defined by service level agreements that are based on required performance and capacity. Active IQ Unified Manager provides a few predefined PSLs, such as Extreme Performance, Performance, and Value, and also allows you to create your own PSLs to meet your needs. You can also apply the PSLs to multiple clusters and workloads to ensure optimal performance and utilization of the underlying resources. References = Performance Service Levels, Managing Performance Service Levels

= Intercluster LIFs are logical interfaces that enable communication between clusters for data replication and caching. The minimum number of intercluster LIFs required on a cluster depends on the number of nodes, the number of IPSpaces, and the network topology. According to the NetApp documentation, the following are the requirements for intercluster LIFs:

• At least one intercluster LIF must be configured on every node in the local cluster, and on every node in the remote cluster. Provisioning intercluster LIFs on only some nodes of the cluster is not supported.
• Each intercluster LIF requires an IP address dedicated for intercluster communication. The IP addresses assigned to intercluster LIFs can reside in the same subnet as data LIFs or in a different subnet.
• Every intercluster LIF on every node of the local cluster should be able to connect to every intercluster LIF on every node of the remote cluster. The cluster peering topology should use full-mesh connectivity. Full-mesh connectivity means that all the Intercluster LIFs of one peer cluster can communicate with all of the Intercluster LIFs of the other peer cluster.

Based on these requirements, the minimum number of intercluster LIFs required on a 4-node cluster is 8, assuming that there is only one IPspace and a full-mesh network topology. This means that each node has one intercluster LIF that can connect to the intercluster LIFs of the other nodes in the same cluster and the remote cluster. If thereare more IPSpaces or a different network topology, the number of intercluster LIFs may vary. References = What is an Intercluster network?, Create intercluster LIFs (Beginning with ONTAP 9.3), Create intercluster interfaces on all nodes (ONTAP 9.2 or earlier)

StorageGRID supports two kinds of access policies: bucket policies and group policies. Bucket policies are attached to buckets and control access by users in the bucket owner account or other accounts to the bucket and the objects in it. Group policies are attached to a group in the account and allow that group to access specific resources owned by that account. Both bucket and group policies use the Amazon Web Services (AWS) policy language and are written in JSON. References = Bucket and group access policies, Use bucket and group access policies, Example group policies.

BlueXP tiering is a NetApp technology that enables you to free space on your on-premises NetApp ONTAP clusters by migrating inactive data to Amazon S3. BlueXP tiering is a data tiering service that automatically moves cold data from your on-premises ONTAP volumes to low-cost object storage in the cloud. BlueXP tiering uses a Connector, which is a virtual machine that runs in your AWS VPC or on your premises, to create and manage an S3 bucket for tiering. BlueXP tiering also provides data protection, encryption, and compression features to ensure the security and efficiency of your data. References = Tiering data from on-premises ONTAP clusters to Amazon S3 | NetApp Documentation, BlueXP Tiering | NetApp Cloud Central.

= 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 efficiencies. References = Learn about BlueXP tiering, Cloud Tiering: Free up Space on On-Premises Storage Systems

= Adding a new FAS system to the existing AFF cluster is a way to expand the storage capacity with cost-effective nearline storage for archiving purposes. A FAS system can use HDDs as the performance tier and tier cold data to cloud object storage using FabricPool, which is a NetApp data tiering technology that reduces the amount of physical capacity taken up by data. This way, the administrator can leverage the storage efficiencies of ONTAP and the low-cost storage of the cloud to archive data that is not frequently accessed. The AFF and FAS systems can be managed by the same ONTAP cluster and provide seamless data access and protection. References = Storage Efficiencies - NetApp, Data Archiving: Cost-Effective Cloud Storage - NetApp, AFF Systems and Cloud Volumes ONTAP | NetApp.

= To activate the destination volume for data access, you must quiesce and break the SnapMirror relationship. Quiescing disables future SnapMirror data transfers, and breaking makes the destination volume read-write. This allows you to use the destination volume for disaster recovery purposes. References = Breaking the SnapMirror relationship, Manage mirror relationships with System Manager, Create the SnapMirror relationship

 NetApp Storage Encryption (NSE) and NVMe self-encrypting drives (SED) are two NetApp products that offer hardware encryption. Hardware encryption is a method of encrypting data at the disk level using a hardware-accelerated mechanism. NSE requires all drives in an HA pair to be purpose-built, self-encrypting drives. These drives perform the data encryption themselves through a hardware-accelerated mechanism. Because of the hardware acceleration, NSE systems usually outperform NVE systems when encrypting data1. NVMe self-encrypting drives (SED) are a type of NSE drives that use the NVMe protocol to provide high performance and low latency. NVMe SEDs are supported on select NetApp AFF systems2. References = Configure NetApp hardware-based encryption overview, Netapp Encrypts Data at Rest and in Transit, Which hardware platforms support software-based encryption (NVE and NAE …, How does NVE and NAE encrypt data? - NetApp Knowledge Base

 ONTAP software is a NetApp storage system that supports NVMe-over-TCP, which is a protocol that allows remote direct memory access for data using an Ethernet TCP link. ONTAP software enables customers to upgrade their iSCSI-based workloads to NVMe-over-TCP without requiring any special hardware or network changes. ONTAP software also provides other benefits such as data protection, efficiency, and scalability for SAN environments. References = Announcing NVMe/TCP for ONTAP, NetApp brings NVMe over TCP to ONTAP via the iSCSI upgrade path, What Is NVMe? - Benefits & Use Cases

 = When provisioning SAN, the host owns the file system. A LUN is a logical unit of storage that is presented to the host as a SCSI device. The host can format the LUN with any file system it supports, such as NTFS, ext4, or XFS. The ONTAP software does not manage the file system on the LUN, but only provides the block-level access to the LUN. The volume is a logical container for one or more LUNs, but it does not own the file system either. References = SAN Concepts, LUNs and Volumes

 BlueXP backup and recovery enables you to perform volume, file, and folder-level restore operations from the cloud or on-premises object store. You can restore entire volumes or specific files or folders from any backup file. You can also use the catalog search feature to find and restore files based on a query. References = Learn about BlueXP backup and recovery, BlueXP backup and recovery APIs, [Restore data from the cloud]

 FlexClone is an ONTAP feature that allows you to instantly create writable virtual copies of data volumes, files, and LUNs, which do not consume storage space. A FlexClone volume, file, or LUN is a writable point-in-time image of the FlexVol volume or another FlexClone volume, file, or LUN. FlexClone is based on Snapshot technology, which captures a read-only image of a volume at a given point in time. FlexClone is perfect for DevOps and test environments, where multiple copies of a database are needed for testing or development purposes. References = NetApp ONTAP, Storage efficiency features, Storage Snapshots Deep Dive: Cloud Volumes ONTAP Snapshots

S3 Object Lock is a StorageGRID feature that enables a compliant information lifecycle management (ILM) policy to prevent object deletion. S3 Object Lock allows you to apply a retention period and a legal hold to individual objects or object versions in buckets with S3 Object Lock enabled. During the retention period, objects cannot be overwritten or deleted unless the legal hold is in effect. If an object is under a legal hold, it cannot be deleted even after the retention period expires. S3 Object Lock helps you to meet regulatory compliance, privacy, and data protection requirements for your object data. References = Manage objects with S3 Object Lock, Example 7: Compliant ILM policy for S3 Object Lock, NetApp StorageGRID ILM on tape
