What's new in this release

OnCommand Unified Manager 9.5 includes several new features and enhancements.

Unified Manager is localized for Japanese and Chinese installations
Customers in China and Japan can install the product and view the graphical user interface and documentation in their own language. For this release the product is available in Japanese and Chinese.
Additional support of FabricPool functionality
Many new FabricPool features have been added to ONTAP and to Unified Manager to help you monitor and manage your data more efficiently using FabricPool aggregates:
  • Displays aggregate and cluster information for FabricPool aggregates created on the newly supported cloud tier providers IBM Cloud Object Storage and Alibaba Cloud Object Storage.
  • Displays if Cold Data Detection is enabled on an aggregate.
  • Displays the size of the user data stored on a volume that is inactive (cold).
  • Analyzes each volume and identifies when a volume would benefit from tiering inactive data to the cloud tier.
  • Provides a link to open the Volumes page in System Manager from volumes that could benefit from moving cold data to the cloud tier so that you can make the change easily.
  • Provides a new event for "Capacity Tier Planning Recommendation" to notify you when you can improve your storage system's disk utilization and save space on the performance tier by moving inactive (cold) data from volumes to the cloud tier. The analysis is run weekly on each cluster to determine if the event is raised.
  • SnapVault data backups and restores can be performed from ONTAP to a destination on a FabricPool aggregate when using ONTAP 9.5 and Unified Manager 9.5, or greater.
New qtree capacity thresholds
You can configure global health threshold values that apply all qtrees, and individual qtree thresholds to customize the threshold for individual qtrees. If the thresholds are breached, you are notified by new events for Qtree Space Nearly Full and Qtree Space Full.
Note: When you upgrade to Unified Manager 9.5, qtree threshold events are triggered only when the state (disk usage) of existing qtrees change. This is also true when you change a qtree threshold after upgrade. Qtrees that exceed the threshold prior to the upgrade, or prior to the threshold change, do not trigger events until the qtree disk usage has changed.
New adaptive QoS threshold policy that factors in block size when evaluating if peak IOPS/TB has been breached
A new variant of the existing "QoS Peak IOPS/TB" system-defined performance threshold has been added that considers the block size that has been set. When the "block size" element has been defined in an adaptive QoS policy (using ONTAP 9.5 and greater), the threshold is converted into a QoS maximum MBps value based on the size of each volume. Volumes that have exceeded the calculated QoS max MBps threshold for the previous hour with trigger the event.

Depending on the block size that is set on the client that generates the workloads, some I/O operations include much more data and therefore place a much larger burden on the nodes that process the operations. See the topic "Understanding events from adaptive QoS policies that have a defined block size" in the online help for more details.

New Unified Manager maintenance window functionality
You can define a Unified Manager maintenance window to suppress events and alerts for a specific timeframe when you have scheduled cluster maintenance and you do not want to receive a flood of unwanted notifications. During a maintenance window the events related to all objects on that cluster are still generated, but they do not appear in any of the UI pages, and no alerts or other types of notification are sent for these events. See the topic "What a Unified Manager maintenance window is" in the online help for more details.
Additional ONTAP subsystem latency amounts are exposed in Unified Manager to help determine the cause of workload latency
The Cluster Components option in the Volume Explorer latency chart provides details about the latency that exists from two additional ONTAP components that affect workload performance:
  • SnapMirror Synchronous - Indicates that the activity from replicating user data from the primary volume to the secondary volume in a SnapMirror Synchronous relationship is impacting the latency of other workloads.
  • Cloud Latency - Indicates that a large amount of reads from volumes that are hosted on the cloud tier are impacting the latency of other workloads. This may indicate that active data should be returned to the performance tier.
Additional EMS events have been added to Unified Manager and the Health and Performance event support has been further integrated
  • Twenty-two EMS events have been added directly from ONTAP as Unified Manager events. These events, when enabled, generate Unified Manager alerts as soon as the ONTAP event occurs. See the topic "EMS events that are added automatically to Unified Manager" in the online help for details.
  • The Dynamic Threshold Event Details page has been redesigned to look like the standard Event details page when displaying dynamic performance events. This page also includes more charts to help diagnose the event.
SnapMirror Synchronous relationships created in ONTAP can be monitored in Unified Manager
  • Discover and monitor SnapMirror Synchronous relationships
  • View details of SnapMirror Synchronous policies
  • View volumes mirrored with SnapMirror Synchronous in the protection topology
  • View and download protection reports including SnapMirror Synchronous relationships
  • Many existing SnapMirror events apply to both synchronous and asynchronous relationships, and three new events have been added for synchronous relationship.
Note that Mirror and Vault relationship types are not currently supported in Unified Manager.
Additional enhancements
  • Support of the ONTAP Logical Space Enforcement feature, including a new field in the Health/Volume Details page under the Capacity tab, and three new events.
  • Support for qtrees when on a FlexGroup volume.
  • Ability to view hourly performance latency statistics for the volumes and LUNs that you have subscribed to the Performance Guarantee program to verify that latency has not exceeded the level you have been guaranteed.
  • Performance latency charts have added a category for "other" latency in addition to read and write values to help in troubleshooting performance issues.
  • Ability to generate a smaller support bundle that does not include performance statistics when performance statistics are not required.
ONTAP software support
Unified Manager 9.5 supports ONTAP 9.5, 9.4, 9.3, 9.2, 9.1, 9.0, and 8.3.x releases. ONTAP 8.2.x and earlier releases are not supported.
Note: Infinite volumes are not supported starting with ONTAP 9.5, so Unified Manager does not show Infinite volumes when monitoring ONTAP 9.5 systems.
New platforms support
Unified Manager 9.5 supports ONTAP Select, Cloud Volumes ONTAP, and all the FAS platforms that are supported in ONTAP 9.5 and earlier.
Note: If you are planning to monitor Cloud Volumes ONTAP systems, Unified Manager must be installed in the same cloud provider environment.
