ONTAP 9.16.1 highlights

ONTAP 9.16.1 delivers new and enhanced features in the areas of security management, data protection, networking, SAN management, and storage management. For a complete list of new features and enhancements, see What's new in ONTAP 9.16.1.

  • Multi-admin verification (MAV) enhancements

    ONTAP 9.16.1 adds more commands to the MAV framework for additional protection from malicious insiders. These enhancements include many Consistency Group (CG), VScan and Autonomous Ransomware Protection (ARP) management, and NVMe configuration commands.

  • Autonomous Ransomware Protection with AI enhancements (ARP/AI)

    ARP has been upgraded with new AI capabilities, allowing it to detect and respond to ransomware attacks with 99% precision and recall. Because the AI is trained on a comprehensive dataset, there is no longer a learning period for ARP running on FlexVol volumes and ARP/AI starts in active mode right away. ARP/AI also introduces an automatic update capability independent of an ONTAP upgrade to ensure constant protection and resilience against the latest threats.

  • NVMe/TCP over TLS 1.3

    Protect NVMe/TCP "over the wire" at the protocol layer with a simplified configuration and improved performance compared to IPSec.

  • IPSec HW offload support for new network cards

    ONTAP 9.16.1 offers higher "over-the-wire" encryption performance when utilizing the IPSec hardware offload functionality on offload cards introduced in the newest generation of AFF A-series and AFF-C series systems platforms.

  • Support for NVMe space deallocation

    Space deallocation (also called "hole punching" and "unmap") is now supported for NVMe namespaces. Space deallocation helps thin-provisioned volumes and NVMe namespaces to reclaim unused space when data is deleted by the host application. This greatly improves overall storage efficiency, especially with filesystems that have high data turnover.

  • Advanced capacity balancing for FlexGroup volumes

    NetApp FlexGroup volumes can optionally stripe data within a single file across multiple back-end constituent volumes, reducing performance bottlenecks, and adding consistency in balancing capacity across the backend constituent volumes.

  • SVM data mobility support for migrating MetroCluster configurations

    ONTAP supports the following MetroCluster SVM migrations:

    • Migrating an SVM between a non-MetroCluster configuration and a MetroCluster IP configuration

    • Migrating an SVM between two MetroCluster IP configurations

    • Migrating an SVM between a MetroCluster FC configuration and a MetroCluster IP configuration

ONTAP 9.15.1 highlights

This new class of systems provides up to twice the performance of existing AFF A-series offerings and delivers "always on" improved storage efficiency without performance trade-offs.

  • Windows backup applications and Unix-style symlinks on servers

    Beginning with ONTAP 9.15.1, you also have the option of backing up the symlink itself instead of the data it points to. This can provide several benefits, including improved performance of your backup applications. You can enable the feature using the ONTAP CLI or ONTAP REST API.

  • Dynamic authorization

    ONTAP 9.15.1 introduces an initial framework for dynamic authorization, a security feature that can determine whether a command issued by an administrator account should be denied, prompted for additional authentication, or allowed to proceed. Determinations are based on the user account's trust score, taking into account factors such as time of day, location, IP address, trusted device usage, and the user's authentication and authorization history.

  • Expanded scope of impact for Multi-admin verification

    ONTAP 9.15.1 RC1 adds over a hundred new commands to the MAV framework for additional protection from malicious insiders.

  • TLS 1.3 encryption support for cluster peering and more

  • Support for SMTP traffic over TLS

    Securely transfer AutoSupport data over e-mail with TLS support.

  • SnapMirror active sync for symmetric active/active configurations

    This new capability provides synchronous bi-directional replication for business continuity and disaster recovery. Protect your data access for critical SAN workloads with simultaneous read and write access to data across multiple failure domains, enabling uninterrupted operations and minimizing downtime during disasters or system failures.

    Performance and capacity monitoring provides detailed for each consistency group, enabling you to quickly identify and report potential issues at the application level rather than just at the data object level.

  • Tenant capacity management

    Multi-tenant customers and service providers can set a capacity limit on each SVM, allowing tenants to perform self-service provisioning without the risk of one tenant over-consuming capacity on the cluster.

  • Quality of Service ceilings and floors

    ONTAP 9.13.1 allows you to group objects such as volumes, LUNs, or files into groups and assign a QoS ceiling (maximum IOPs) or floor (minimum IOPs), improving application performance expectations.

ONTAP 9.12.1 highlights

ONTAP 9.12.1 delivers new and enhanced features in the areas of security hardening, retention, performance, and more. For a complete list of new features and enhancements, see What's new in ONTAP 9.12.1.

  • Tamper-proof Snapshots

    With SnapLock technology, snapshots can be protected from deletion on either the source or destination.

    Retain more recovery points by protecting snapshots on primary and secondary storage from deletion by ransomware attackers or rogue administrators.

  • Autonomous Ransomware Protection (ARP) enhancements

    Immediately enable intelligent autonomous ransomware protection on secondary storage, based on the screening model already completed for the primary storage.

    After a failover, instantly identify potential ransomware attacks on secondary storage. A snapshot is immediately taken of the data that is starting to be affected, and administrators are notified, helping to stop an attack and enhance recovery.

  • FPolicy

    One-click activation of ONTAP FPolicy to enable automatic blocking of known malicious files The simplified activation helps to protect against typical ransomware attacks that use common, known file extensions.

  • Security hardening: Tamper-proof retention logging

    Tamperproof retention logging in ONTAP insuring compromised administrator accounts cannot hide malicious actions. Admin and user history cannot be altered or deleted without the systems knowledge.

    Log and audit all admin actions regardless of origin guaranteeing all actions impacting data are captured. An alert is generated whenever system audit logs have been tampered with in any way notifying administrators of the change.

  • Security hardening: Expanded multifactor authentication

    Multifactor authentication (MFA) for CLI (SSH) supports Yubikey physical hardware token devices ensuring that an attacker cannot access the ONTAP system using stolen credentials or a compromised client system. Cisco DUO is supported for MFA with System Manager.

  • File-object duality (multi-protocol access)

    File-object duality enables native S3 protocol read and write access to the same data source that already has NAS protocol access. You can concurrently access your storage as files or as objects from the same data source, eliminating the need for duplicate copies of data for use with different protocols (S3 or NAS), such as for analytics that use object data.

  • FlexGroup rebalancing

    If FlexGroup constituents become unbalanced, FlexGroup can nondisruptively be rebalanced and managed from the ONTAP CLI, ONTAP REST API, and System Manager. For optimal performance, constituent members within a FlexGroup should have their used capacity evenly distributed.

  • Storage capacity enhancements

    WAFL space reservation has been significantly reduced, providing up to 40 TiB more usable capacity per aggregate.
