How Amazon FSx for NetApp ONTAP works

This topic introduces the major features of Amazon FSx for NetApp ONTAP and how they work, along with links to the sections with important implementation details.

FSx for ONTAP file systems

A file system is the primary FSx for ONTAP resource, analogous to an on-premises NetApp ONTAP cluster. You specify the solid state drive (SSD) storage capacity and throughput capacity for your file system, and choose an Amazon Virtual Private Cloud (VPC) where your file system is created. For more information, see Managing FSx for ONTAP file systems.

Storage virtual machines

A storage virtual machine (SVM) is an isolated file server with its own administrative and data access endpoints for administering and accessing data. When you access data in your FSx for ONTAP file system, your clients and workstations interface with an SVM using the SVM's endpoint IP address. For more information, see Managing SVMs.

You can join SVMs to a Microsoft Active Directory for file access authentication and authorization. For more information, see Working with Microsoft Active Directory in FSx for ONTAP.

Volumes

FSx for ONTAP volumes are virtual resources that you use for organizing and grouping your data. Volumes are logical containers, and data stored in them consumes physical capacity on your file system. Volumes are hosted on SVMs. When you create a volume, you set its size, which determines the amount of physical data that you can store in it, regardless of which storage tier it is on.

Volumes are thin provisioned, meaning that they only consume storage capacity for the data stored in them. For example, you can create three 10 TiB volumes on a file system configured with 10 TiB of free storage capacity, as long as the total amount of storage in the three volumes doesn't exceed 10 TiB at any time. Only a volume's used capacity counts toward your storage capacity consumption. For more information, see Managing FSx for ONTAP volumes.

Storage tiers

An FSx for ONTAP file system has two storage tiers: primary storage and capacity pool storage. Primary storage is provisioned, scalable, high-performance SSD storage that’s purpose-built for the active portion of your data set. Capacity pool storage is a fully elastic storage tier that can scale to petabytes in size and is cost optimized for infrequently accessed data. Data that you write to your volumes consumes capacity on your storage tiers. For more information, see FSx for ONTAP storage tiers.

Data tiering

Data tiering is the process by which Amazon FSx for NetApp ONTAP automatically transitions file system data between the SSD and the capacity pool storage tiers. Each volume has a tiering policy that determines whether a volume uses your file system’s capacity pool storage tier, and how. A volume's size determines how much total data you can store in it, while the volume's tiering policy determines which storage tier the data resides on. For more information, see Volume data tiering.

Storage efficiency

Amazon FSx for NetApp ONTAP supports ONTAP’s block-level storage efficiency features—compaction, compression, and deduplication—to reduce the storage capacity that your data consumes. Storage efficiency features can reduce the footprint of your data in SSD storage, capacity pool storage, and backups. The typical storage capacity savings for general purpose file sharing workloads without sacrificing performance is 65% from compression, deduplication, and compaction, on both the SSD and capacity pool storage tiers. For more information, see FSx for ONTAP storage efficiency.

Accessing data stored on FSx for ONTAP file systems

You can access your data on FSx for ONTAP volumes from multiple Linux, Windows, or macOS clients simultaneously over the NFS (v3, v4, v4.1, v4.2) and SMB protocols. You can also access data using the iSCSI (block) protocol. For more information, see Accessing data.

Managing FSx for ONTAP resources

There are several ways that you can interact with your FSx for ONTAP file system and manage its resources. You can manage your FSx for ONTAP resources using both AWS and NetApp ONTAP management tools:

  • AWS management tools

    • The AWS Management Console

    • The AWS Command Line Interface (AWS CLI)

    • The Amazon FSx API and SDKs

    • AWS CloudFormation

  • NetApp management tools:

    • NetApp Cloud Manager

    • The NetApp ONTAP CLI

    • The NetApp ONTAP REST API
