Data warehouse rebuild indicator for SnapMirror asynchronous

SnapMirror asynchronous provides an indicator showing how long a data warehouse rebuild takes after a disaster recovery rehearsal by displaying the percentage complete.

SnapLock option to set minimum retention time "unspecified" absolute retention time

SnapLock includes an option to set a minimum retention time when the absolute retention time is set to "unspecified".

Tamperproof Snapshot copies

You can lock a Snapshot copy on a non-SnapLock volume to provide protection from ransomware attacks. Locking Snapshot copies helps ensure that they are not deleted accidentally or maliciously.

File access protocols

Update Description

Disable weak encryption types for Kerberos communication

A new SMB security option allows you to disable RC4 and DES in favor of Advanced Encryption Standard (AES) encryption types for Kerberos-based communication with the Active Directory (AD) KDC.

S3 client access to NAS data

S3 clients can access the same NAS data as NFS and SMB clients without reformatting, making it easier to serve S3 applications that require object data.

NFS extended attributes

NFS servers enabled for NFSv4.2 can store and retrieve NFS extended attributes (xattrs) from xattr-aware clients.

NFSv4.2 sparse files and space reservation support

The NFSv4.2 client is able to reserve space for a sparse file. Space can also be deallocated and unreserved from a file.

MetroCluster

Update Description

ONTAP Mediator 1.5 is supported in a MetroCluster IP configuration

ONTAP Mediator 1.5 is available for monitoring MetroCluster IP configurations.

IPsec support for front-end host protocol (such as NFS and iSCSI) is available in MetroCluster IP and MetroCluster fabric-attached configurations.

IPsec support for front-end host protocol (such as NFS and iSCSI) is available in MetroCluster IP and MetroCluster fabric-attached configurations.

MetroCluster automatic forced switchover feature in a MetroCluster IP configuration

You can enable the MetroCluster automatic forced switchover feature in a MetroCluster IP configuration. This feature is an extension of the Mediator-assisted unplanned switchover (MAUSO) feature.

S3 on an SVM on an unmirrored aggregate in a MetroCluster IP configuration

You can enable the MetroCluster automatic forced switchover feature in a MetroCluster IP configuration. This feature is an extension of the Mediator-assisted unplanned switchover (MAUSO) feature.

Networking

Update Description

LIF services

You can use the management-log-forwarding service to control which LIFs are used to forward audit logs to a remote syslog serve

S3 object storage

Update Description

Expanded support for S3 actions

The following Amazon S3 API actions are supported:

  • CopyObject

  • UploadPartCopy

  • BucketPolicy (GET, PUT, DELETE)

SAN

Update Description

Increased maximum LUN size for ETERNUS AX and ETERNUS HX Series

Beginning with ONTAP 9.12.1P2, the maximum supported LUN size on ETERNUS AX and ETERNUS HX Series increased from 16 TB to 128 TB.

Increased NVMe limits

The NVMe protocol supports the following:

  • 8K subsystems in a single storage VM and a single cluster

  • 12 node clusters NVMe/FC supports 256 controllers per port and NVMe/TCP supports 2K controllers per node.

NVME/TCP support for secure authentication

Secure, unidirectional and bidirectional authentication between an NVMe host and controller is supported over NVMe/TCP using the DHHMAC-CHAP authentication protocol.

MetroCluster IP support for NVMe

The NVMe/FC protocol is supported on 4-node MetroCluster IP configurations.

Security

In October 2022, Fujitsu implemented changes to reject AutoSupport message transmissions that are not sent by either HTTPS with TLSv1.2 or secure SMTP.

Feature Description

Autonomous Ransomware Protection interoperability enhancements

Autonomous Ransomware Protection is available for these configurations:

  • Volumes protected with SnapMirror

  • SVMs protected with SnapMirror

  • SVMs enabled for migration (SVM data mobility)

Multifactor authentication (MFA) support for SSH with FIDO2 and PIV (both used by Yubikey)

SSH MFA can use hardware-assisted public/private key exchange with username and password. Yubikey is a physical token device that is plugged into the SSH client to increase MFA security.

Tamper-proof logging

All ONTAP internal logs are tamperproof by default, ensuring that compromised administrator accounts cannot hide malicious actions.

TLS transport for events

EMS events can be sent to a remote syslog server using the TLS protocol, thereby enhancing protection over the wire for central external audit logging.

Storage efficiency

Update Description

Temperature-sensitive storage efficiency

Temperature-sensitive storage efficiency is enabled by default on new ETERNUS AC2100 and ETERNUS AC4100 series and volumes. TSSE is not enabled by default on existing volumes but can be enabled manually using the ONTAP CLI.

Increase in usable aggregate space

For ETERNUS AX and the FAS500f series, the WAFL reserve for aggregates greater than 30TB is reduced from 10% to 5%, resulting in increased usable space in the aggregate.

File System Analytics: Top directories by size

File System Analytics now identifies the directories in a volume that are consuming the most space.

Storage resource management enhancements

Update Description

FlexGroup rebalancing

You can enable automatic nondisruptive FlexGroup volume rebalancing to redistribute files between FlexGroup constituents.

It’s recommended that you do not use automatic FlexGroup rebalancing after a FlexVol to FlexGroup conversion. Instead, you can use the disruptive retroactive file move feature available in ONTAP 9.10.1 and later, by entering the volume rebalance file-move command. For more information and command syntax, see the ONTAP Command Reference.

SnapLock for SnapVault support for FlexGroup volumes

SnapLock for SnapVault support for FlexGroup volumes

SVM management enhancements

Update Description

SVM data mobility enhancements

Cluster administrators can non-disruptively relocate an SVM from a source cluster to a destination cluster using ETERNUS HX series, ETERNUS AX series, on hybrid aggregates. Support for both disruptive SMB protocol and Autonomous Ransomware Protection have been added.

ONTAP System Manager

Beginning with ONTAP 9.12.1, ONTAP System Manager is integrated with BlueXP. With BlueXP, administrators can manage the hybrid multicloud infrastructure from a single control plane while retaining the familiar ONTAP System Manager dashboard. When signing into ONTAP System Manager, administrators are given the option of accessing the ONTAP System Manager interface in BlueXP or accessing ONTAP System Manager directly.
