Learn about the new capabilities available in ONTAP 9.18.1.

For details about known issues, limitations, and upgrade cautions in recent ONTAP 9 releases, refer to the ONTAP 9 Release Notes. You must sign in with your NetApp account or create an account to access the Release Notes.

To upgrade to the latest version of ONTAP, see Prepare to upgrade ONTAP.

Networking

Update Description

IPsec hardware offload IPv6 support

IPsec hardware offload support is extended to IPv6.

OpenSSL PQC algorithms

ONTAP supports postquantum computing cryptographic algorithms for SSL. These algorithms provide additional protection against potential future quantum computing attacks, and are available when SSL FIPS mode is disabled.

ONTAP backend cluster network encryption

You can enable TLS encryption for data-in-flight on the ONTAP backend cluster network.

ONTAP HA traffic network encryption

You can enable encryption for traffic between nodes in high-availability (HA) pairs.

SAN

Update Description

NVMe copy offload

NVMe copy offload enables an NVMe host to offload copy operations from its CPU to the CPU of the ONTAP storage controller. The host can copy data from one NVMe namespace to another while reserving its CPU resources for application workloads.

S3 object storage

Update Description

Support for point-in-time S3 snapshot restore

Provides the ability to restore corrupted objects in an S3 bucket, or restore the entire bucket over an existing bucket.

Security

Update Description

FlexGroup volume support for ARP/AI

NetApp FlexGroup volumes support ARP/AI, providing advanced, machine-learning-based ransomware detection and protection. In ONTAP 9.17.1 and earlier, only the first generation of ARP was available for FlexGroup volumes. Beginning with ONTAP 9.18.1, FlexGroup volumes have parity with FlexVol volumes on both on-premises ONTAP platforms (AFF and FAS) and virtual ONTAP deployments (including Cloud Volumes ONTAP and ONTAP Select). As a result, ARP/AI becomes the default ARP technology for both FlexVol and FlexGroup volumes.

Storage resource management enhancements

Update Description

Support for two-level nested QoS policy groups on SVMs and volumes

You can assign a QoS policy to an SVM and to volumes under the SVM at the same time.

Create SVM FlexCache volumes of origin volumes in an SVM-DR relationship

You can create SVM FlexCache volumes of origin volumes that are part of an SVM-DR relationship.
