ONTAP Unified Data Storage Management
NetApp ONTAP, the industry's leading storage management software, breaks down silos and unifies storage and data, providing a single platform for all of your data across all your locations throughout the lifecycle of the data.
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.

ONTAP Features and Benefits
Data compaction
Benefit: Works with compression to reduce the amount of storage that you need to purchase and operate
Data compression
Benefit: Reduces the amount of storage that you need to purchase and maintain
Deduplication
Benefit: Reduces the amount of storage that you need to purchase and maintain
FabricPool
Benefit: Decreases storage costs for cold data and frees up space on your high-performance tier
FlexCache
Benefit: Accelerates read performance for hot datasets by increasing data throughput within a cluster, and improves the speed and productivity of collaboration across multiple locations
FlexClone
Benefit: Saves you time in testing and development and increases your storage capacity
FlexGroup
Benefit: Supports compute-intensive workloads and data repositories that require a massive NAS container while maintaining consistent high performance and resilience
FlexVol
Benefit: Enables storage systems to be used at maximum efficiency and reduces hardware investment
MetroCluster
Benefit: Maintains business continuity for critical enterprise applications and workloads if a data center disaster occurs
Multi-Admin Verification
Benefit: Prevents malicious and accidental changes to your data. A single cluster administrator, or a ransomware attacker with a compromised administrator account, cannot execute critical commands without approvals from one or more additional administrators
Dynamic authorization framework
Benefit: Creates an additional layer of protection to prevent malicious actors using compromised credentials from performing highly controlled or destructive actions
Performance capacity
Benefit: Simplifies management and enables more effective provisioning of new workloads to the optimal node
QoS (adaptive)
Benefit: Simplifies operations and maintains consistent workload performance within your prescribed minimum and maximum IOPS boundaries
Ransomware protection
Benefit: Defends against ransomware attacks and enables quick recovery, to strengthen the overall security posture at the storage layer
SnapCenter
Benefit: Offers application-aware backup and clone management; automates error-free data restores
SnapLock
Benefit: Supports regulatory compliance and organizational data retention requirements; plus, enables air-gap separation of Snapshot copies for enhanced ransomware protection and quick recovery from an attack
SnapMirror
Benefit: Provides flexibility and efficiency when replicating data to support remote backup/recovery, disaster recovery, and data distribution
SnapMirror active sync
Benefit: Cost-effectively protects the most critical SAN applications with continuous availability to maintain business continuity if a data center disaster occurs
SnapMirror Cloud
Benefit: Provides flexibility and efficiency when replicating data to a cloud object store in a public or private cloud, to support remote backup/recovery, disaster recovery, and data distribution
SnapMirror Synchronous
Benefit: Achieve zero-data-loss protection (RPO=0)
SnapRestore
Benefit: Instantaneously recovers files, databases, and complete volumes from your point-in-time Snapshot copy
Snapshot
Benefit: Enables you to create frequent space-efficient backups with no disruption to data traffic
NetApp Volume Encryption
Benefit: Lets you easily and efficiently protect your at-rest data by encrypting any volume on an AFF or FAS system; no special encrypting disks are required
