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.

HTTPS and NFS are two protocols that are supported in StorageGRID. HTTPS is the protocol used for secure communication between clients and StorageGRID nodes1. NFS is the protocol supported by the StorageGRID NAS protocol bridge, which enables object access to files stored on NAS devices using the Amazon S3 API23. References = 1: StorageGRID 11.6 Documentation - NetApp, 2: Datasheet NetApp StorageGRID, 3: NetApp Datasheet - NetApp StorageGRID Webscale Object Storage Software.

A file is a data type that represents a collection of data stored on a disk or other storage device. A file can have a name, an extension, a size, and other attributes. A file can contain any kind of data, such as text, images, audio, video, etc. A file can be opened, read, written, closed, deleted, or moved by a program. An object is a data type that represents an instance of a class, which is a blueprint for creating objects. An object can have properties, which are variables that store data, and methods, which are functions that perform actions on the object. An object can interact with other objects by sending and receiving messages. An object can inherit properties and methods from its parent class, or override them with its own definitions. References = File data type, Object data type, NetApp Data ONTAP 8.3 File Access and Protocols Management Guide, NetApp Data ONTAP 8.3 Object-Store Configuration Guide

BlueXP edge caching is a NetApp BlueXP product that enables a customer to provide read and write access to remote Windows servers from a centralized datastore. BlueXP edge caching allows you to cache data from a BlueXP volume or a Cloud Volume ONTAP system on a local Windows server, which improves the performance and availability of your applications. You can also sync the cached data back to the source volume, ensuring data consistency and protection. References = BlueXP edge caching overview, BlueXP edge caching documentation, BlueXP edge caching: Accelerate access to your data

= 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.

 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
