ONTAP makes storage simple

ONTAP: The Power Behind Every NetApp Innovation

ONTAP is the operating system that powers every NetApp storage product, on premises and in the cloud. Enterprise customers trust ONTAP to manage over 100 exabytes of data. Its flexibility allows it to adapt to any workload, from terabytes in edge deployments to petabytes in AI data centers. With ONTAP, you get three powerful personalities in one OS: Unified AFF and FAS for extreme versatility across block, file, and object; ASA for simplified, high-performance block workloads; and now AFX, a disaggregated architecture that scales performance and capacity independently to meet the demands of enterprise AI. Every innovation in ONTAP benefits the entire NetApp portfolio, so you get consistent security, automation, and data services, no matter how or where you deploy it.

Get proven storage efficiency

With ONTAP, you get a comprehensive portfolio of storage efficiency capabilities. Inline data compression, deduplication, and compaction work together to reduce your storage costs and maximize the data you can store. Plus, you can multiply your savings with space-efficient NetApp Snapshot copies, thin provisioning, replication, and cloning technologies.

Tier automatically to object storage

ONTAP lets you deliver high performance to your applications and reduce storage costs by automatically tiering cold data from the performance tier to NetApp StorageGRID object storage or ONTAP S3 object storage. Free up space on your performance tier, such as NetApp ASA, AFF, and FAS systems, or Cloud Volumes ONTAP instances in a public cloud so you can consolidate more workloads. For new all-flash system purchases, data tiering means that you can buy a smaller initial AFF or ASA configuration.

Maximize investment protection

ONTAP gives you the flexibility to create an integrated, scalable storage environment by clustering your on-premises storage controllers from different families—AFF all-flash and FAS hybrid-flash systems—and from different generations. You can grow your system with the latest hardware, continue to use your older hardware, and connect all of it to an ONTAP environment in the cloud. When it's time to retire a storage system, you can simply upgrade the controllers and keep your data in place on the existing disk shelves.

Get simple, powerful management capabilities

ONTAP integrates with the NetApp Console to centralize control of your storage and data services in a single, enterprise-ready interface. With one secure login, you can deploy, discover, configure, monitor, and maintain systems across on-premises and cloud environments. Intelligent workflows streamline operations, and integrated data protection services help safeguard your data and strengthen cyber resilience. With a reimagined interface and a security-first foundation, it's never been easier to boost productivity, protect your data, and stay in control.

ONTAP is powerful

Serve any data, anywhere, with the right performance at the right price

To support your critical applications, you need a storage environment that delivers high performance and availability across your hybrid multicloud. But you also need the versatility to scale and adapt as your business changes. ONTAP delivers on all these requirements with performance at scale and nondisruptive operations.

Get flash optimization

ONTAP delivers the high throughput and consistent, submillisecond low latency that enterprise applications require, while providing comprehensive data services. ONTAP is optimized for flash, including ASA and AFF systems with NVMe solid-state drives (SSDs), NVMe over TCP, and NVMe over Fabrics.

Deliver consistent performance

To maintain high customer satisfaction, adaptive quality of service (AQoS) helps you deliver consistent performance by automatically adjusting storage resource levels to respond to changes in workloads (number of terabytes of data, priority of the workload, and so on). AQoS simplifies the implementation of policies to keep your workloads within prescribed minimum and maximum throughput targets.

Stay ahead of business changes with seamless scalability

You can start small and grow with your business by using high-capacity SSDs or HDDs or public cloud to scale your ONTAP storage environment. On-premises systems that run ONTAP can handle SAN, NAS, and object workloads that range from a few terabytes to up to 707PB. You can scale up by adding capacity to existing storage controllers or scale out by adding controllers to seamlessly expand your cluster up to 24 nodes. Or quickly deploy an ONTAP environment in public clouds using Cloud Volumes ONTAP. ONTAP also supports massive NAS data containers that are easy to manage. With NetApp ONTAP FlexGroup volumes, a single namespace can grow to 60PB or 400 billion files while delivering consistent high performance and resilience.

Support your workloads efficiently wherever they run

With ONTAP, you can design and deploy your storage environment across the widest range of architectures, so you can match the approach that's right for your evolving business needs.
  • On NetApp hardware systems. Employ AFF all-flash systems, for the best latency for demanding performance; ASA all-flash systems for block-optimized workloads; and FAS systems, for a balance of performance and capacity.
  • Within a converged infrastructure. FlexPod from NetApp and Cisco is a secure, smart, sustainable, hybrid-ready converged infrastructure platform that helps customers accelerate a large and growing portfolio of modern and enterprise reference architectures.
  • As software-defined storage on commodity servers. ONTAP Select.
  • In the cloud. Cloud Volumes ONTAP, Amazon FSx for NetApp ONTAP, Azure NetApp Files, Google Cloud NetApp Volumes.
You can move your data seamlessly between architectures to place it in the optimal environment for performance, capacity, and cost efficiency.

ONTAP protects your data

Reduce risk with the most secure and available storage

In a world full of threats, whether human-made (such as ransomware) or natural disaster, ONTAP provides the security and availability you need to eliminate risk from operations and enhance business continuity.

Integrated data protection and nondisruptive operations

With ONTAP, you can meet your requirements for local backup with nearly instantaneous recovery by using space-efficient Snapshot copies. Achieve remote backup/recovery and disaster recovery with NetApp SnapMirror asynchronous replication or with SnapMirror Cloud when replicating data to a cloud object store in a public or private cloud. Or, to step up to zero-data-loss protection (RPO=0), use SnapMirror synchronous replication.

Protect business operations from regional outages

For your critical applications that require continuous data availability, NetApp MetroCluster and SnapMirror active sync technologies synchronously mirror between locations to provide business continuity against human-made or natural disasters. The storage arrays can be deployed at a single site, across a metropolitan area, or in different cities. MetroCluster is a robust, full-system infrastructure for your SAN and NAS workloads. SnapMirror active sync enables the flexibility to granularly protect the most critical SAN applications with continuous availability if a data center disaster occurs.

Scale and maintain nondisruptively

With ONTAP, you can service and update your infrastructure during regular working hours without disrupting your business. Dynamically assign, promote, and retire storage resources without downtime over the lifecycle of an application. Data can be moved without application interruption, so you can get the data on the node that delivers the optimal combination of speed, latency, capacity, and cost.

Secure consolidation

You can save time and money by sharing the same consolidated infrastructure for workloads or tenants that have different performance, capacity, and security requirements. And with ONTAP, you don't have to worry that the activity in one tenant partition will affect another. With multitenancy, a storage cluster can be subdivided into secure partitions that are governed by rights and permissions.

Robust security and ransomware protection

Built-in security to harden ONTAP includes ransomware detection for primary storage. Industry-leading security capabilities in ONTAP help you to integrate data security and ransomware detection and response for user behavior and workloads on file, block, and native cloud. NetApp Autonomous Ransomware Protection, powered by AI, offers real-time detection of anomalies with automatic responses for fast recovery. Multiadmin verification prevents malicious and accidental changes to your data by requiring multiple approvals for critical admin tasks. The built-in NetApp Volume Encryption feature enables you to easily protect your at-rest data by encrypting any volume. In-flight encryption for backup and replication protects your data in transit. Other features like multifactor authentication, role-based access control (RBAC), and onboard and external key management increase the security of your data.

Rigorous compliance

To meet your stringent compliance and data retention policies, NetApp SnapLock software enables write once, read many (WORM) protected data for your ONTAP environment. NetApp also provides superior integration with enterprise backup vendors and leading applications. In addition, cryptographic shredding by the NetApp secure purge technology enables you to remediate data spillage online while the system is still in use. It also provides state-of-the-art "right-to-erasure" capability for General Data Protection Regulation (GDPR).
