 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

= 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

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.

FlexCache technology is a feature of NetApp ONTAP that enables you to create a cache volume on a remote cluster and populate it with data from a source volume on a different cluster. The cache volume can serve read requests from local clients, reducing the WAN latency and bandwidth consumption. The cache volume can also be configured to write back to the source volume, ensuring data consistency and availability. FlexCache technology simplifies file distribution by allowing you to create multiple cache volumes across different sites and regions, and manage them from a single interface. References = FlexCache volumes overview - NetApp, FlexCache volumes: Simplify file distribution and reduce WAN latency - NetApp, FlexCache volumes: Use cases and benefits - NetApp.

 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
