 ONTAP software is the data management software that runs on NetApp storage systems and provides the NAS functionality. ONTAP software owns the file system while provisioning NAS and handles the communication with the clients using NFS or SMB protocols. ONTAP software also provides features such as data protection, efficiency, security, and performance for NAS workloads. References = NetApp ONTAP, Provision NAS storage for both Windows and Linux using both NFS and SMB

= A Kubernetes cluster is a group of machines that run containerized applications as part of a distributed system. A Kubernetes cluster consists of two types of nodes: worker nodes and master nodes. Worker nodes are the machines that run the actual workloads, such as pods, which are groups of containers. Master nodes are the machines that run the control plane, which is responsible for managing the cluster state, scheduling workloads, and enforcing policies. A cluster must have at least one master node and one or more worker nodes. A cluster can also have multiple master nodes for high availability and load balancing. References = What is Kubernetes Cluster?, Kubernetes Nodes - The Complete Guide, Nodes | Kubernetes

 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

 FPolicy is an ONTAP feature that enables this functionality. FPolicy is a file access notification framework that allows external applications to monitor and control file access on ONTAP storage systems1. FPolicy can be used to protect files from ransomware by integrating with third-party solutions that use user behavioral analytics (UBA) to detect abnormal activity andtrigger actions such as creating a Snapshot copy and blocking the AD user access23. FPolicy can also be activated with a single click from BlueXP or ONTAP System Manager to protect against common ransomware extensions4. References = 1: FPolicy overview - NetApp, 2: Prevent ransomware spread with ONTAP automatic ransomware protection, 3: Fighting Ransomware, Part Six: Remediation, 4: Proactive ransomware protection—automated with ONTAP - NetApp.

= Dynamic Disk Pools (DDP) is a disk layout type that provides the fastest rebuild time after disk failure on an E-Series system. DDP distributes data, parity, and spare capacity across a pool of disks, instead of using dedicated parity and spare disks. This enables faster and more efficient reconstruction of data in the event of a disk failure, as well as better performance and load balancing. DDP also reduces the risk of data loss due to multiple disk failures, as it can tolerate any number of disk failures up to the pool’s protection level. References = SANtricity OS Dynamic Disk Pools | TR-4652 - NetApp, How to increase priority for disk reconstruction - NetApp Knowledge Base.

ONTAP System Manager is a web-based data management tool that enables customers to provision storage systems and perform common management tasks. ONTAP System Manager provides a simple, intuitive, and centralized interface for managing ONTAP clusters, volumes, LUNs, SVMs, and more. ONTAP System Manager simplifies storage management by automating complex workflows, providing best practices, and offering guided setup and configuration wizards. References = ONTAP System Manager overview, ONTAP Data Management Software

Azure NetApp Files is a fully managed cloud storage service that provides SMB and NFS file services for your cloud applications on Microsoft Azure. It is designed for customers who want to use cloud storage as part of their data strategy and have a mixture of NFS and SMB workloads. Azure NetApp Files simplifies and automates the deployment, management, and scaling of your file systems, while delivering high performance, availability, security, and data protection. You can also leverage NetApp’s data management capabilities, such as snapshots, clones, replication, and backup, to enhance your data lifecycle management. References = What is Azure NetApp Files?, Azure NetApp Files Documentation, Azure NetApp Files: Enterprise-Grade File Storage for Azure, Azure NetApp Files: The Ultimate Cloud File Service

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.

= 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

= The ONTAP Mediator service and the MetroCluster TieBreaker are two NetApp features that can be used to automate switchover in a MetroCluster IP configuration in the event of a site disaster. The ONTAP Mediator service is a software component that monitors the health and connectivity of the MetroCluster nodes and initiates a switchover when it detects a failure of one site or a network partition between the sites. The MetroCluster TieBreaker is a software component that runs on a third site and acts as a quorum witness for the MetroCluster configuration. The MetroCluster TieBreaker prevents split-brain scenarios and enables automatic switchover when one site becomes unavailable or isolated. References = ONTAP Mediator service overview, [MetroCluster TieBreaker overview], Data protection with automatic unplanned switchover in two-node MetroCluster configurations
