Data protection
| Update | Description |
|---|---|
Storage efficiency support on SnapLock volumes and aggregates |
Storage efficiency capabilities for SnapLock volumes and aggregates have been extended to include data compaction, cross-volume deduplication, adaptive compression, and TSSE (Temperature Sensitive Storage Efficiency), allowing for greater space savings for WORM data. |
Support for configuring different Snapshot policies on SVM DR source and destination |
SVM DR configurations can use the mirror-vault policy to configure different Snapshot policies on the source and destination, and the policies on the destination are not overwritten by the policies on the source. |
SnapMirror Cloud is now supported in System Manager. |
|
The maximum number of auditing-enabled SVMs supported in a cluster has been increased from 50 to 400. |
|
The maximum number of supported SnapMirror Synchronous endpoints per HA pair has increased from 80 to 160. |
|
FlexGroup volumes support two or more fanout relationships; for example A→B, A→C. Like FlexVol volumes, FlexGroup fanout supports a maximum of 8 fanout legs, and cascading up to two-levels; for example, A→B→C. |
File access protocols
| Update | Description |
|---|---|
LDAP referral chasing is supported with LDAP signing and sealing, encrypted TLS connections, and communications over LDAPS port 636. |
|
LDAPS can be configured on any port; port 636 remains the default. |
|
NFSv4.0, NFSv4.1, and NFSv4.2 are enabled by default. |
|
Mandatory Access Control (MAC) labeled NFS is supported when NFSv4.2 is enabled. With this functionality, ONTAP NFS servers are MAC-aware, storing and retrieving |
MetroCluster
| Update | Description |
|---|---|
MetroCluster IP configurations can be implemented with IP-routed (layer 3) back-end connections. |
|
Permanent 8-node clusters are supported in IP and Fabric-attached configurations. Additionally, AFF ASA platforms support 8-node MCC IP configurations. |
To learn about platform and switch configuration enhancements for MetroCluster configurations, see the ONTAP 9 Release Notes.
Networking
| Update | Description |
|---|---|
|
|
|
S3 object storage
| Update | Description |
|---|---|
The ONTAP S3 server provides enhanced automation capabilities to S3 clients and applications with support for user-defined object metadata and object tagging. |
SAN
| Update | Description |
|---|---|
The SAN LUN Migrate App on the NetApp Support Site can be used to qualify a foreign array that is not listed in the FLI interoperability matrix. |
|
If direct path access is lost in failover, remote I/O allows the system to failover to a remote path and continue data access. |
|
12-node clusters are supported for AFF ASA configurations. ASA clusters can include a mix of various ASA system types. |
|
The NVMe-oF protocol support is also available with an AFF ASA system. |
|
|
|
Single LUN performance for AFF has been significantly improved, making it ideal for simplifying deployments in virtual environments. For example, A800 can provide up to 400% more Random Read IOPs. |
Security
| Update | Description |
|---|---|
Support for multifactor authentication with Cisco DUO when logging in to System Manager |
Beginning with ONTAP 9.9.1P3, you can configure Cisco DUO as a SAML identity provider (IdP), enabling users to authenticate using Cisco DUO when they log in to System Manager. |
Storage efficiency
| Update | Description |
|---|---|
Automate file maximums with the volume parameter |
Storage resource management enhancements
| Update | Description |
|---|---|
File System Analytics (FSA) management enhancements in System Manager |
FSA provides additional System Manager capabilities for search and filtering, and for taking action on FSA recommendations. |
Caches a "file not found" error on the FlexCache volume to reduce network traffic caused by calls to the origin. |
|
Provides non-disruptive migration of clients from one cache to another. |
|
Provides support for SnapMirror cascade and SnapMirror fanout relationships for FlexGroup volumes. |
|
SVM disaster recovery support for FlexGroup volumes provides redundancy by using SnapMirror to replicate and synchronize an SVM's configuration and data. |
|
Logical space reporting and enforcement support for FlexGroup volumes |
You can display and limit the amount of logical space consumed by FlexGroup volume users. |
SMB access is supported to qtrees in FlexVol and FlexGroup volumes with SMB enabled. |
System Manager
| Update | Description |
|---|---|
Use System Manager to link to NetApp Active IQ, which reports opportunities to reduce risk and improve the performance and efficiency of your storage environment. |
|
System Manager users can assign a local tier manually when they are creating and adding volumes and LUNs. |
|
Directories can be deleted in System Manager with low-latency fast directory delete functionality. |
|
System Manager users can generate Ansible Playbooks from the UI for a few select workflows and can use them in an automation tool to repeatedly add or edit volumes or LUNs. |
|
First introduced in ONTAP 9.8, the Hardware Visualization feature now supports all AFF platforms. |
|
System Manager users can view support cases associated with the cluster and download. They can also copy cluster details they need to submit new support cases on the NetApp Support site. System Manager users can receive alerts from Active IQ to inform them when new firmware updates are available. Then, they can download the firmware image and upload it using System Manager. |
|
System Manager users can set up protection to back up data to public cloud endpoints using the Cloud Backup Service. |
|
System Manager users can manually name a SnapMirror destination and igroup name when setting up data protection. |
|
The network interfaces page has enhanced capabilities to display and manage interfaces on their home ports. |
|
System management enhancements |
|
|
|
Enhanced display in System Manager about capacity and location information for storage tiers |
|
Display in System Manager of EMS emergency alerts and other errors and warnings |
The number of EMS alerts received in 24 hours, as well as other errors and warnings, are shown in the Health card in System Manager. |
