What’s New: Nutanix AOS 6.1 and Prism Central 2022.1.

Today Nutanix announce the release of new AOS and Prism Central versions with performance enhancements and key features to raise the bar with new milestones.

Below are some of the salient features as part of the release.

AOS 6.1 (STS)

NOTE: AOS 6.1 is Short Term Release

Improved Single vDisk Performance: This feature enabled multithreaded vDisk controller where based on size and IO of the vDisk, the IO will be sharded to multiple threads. This will improve the performance of workload where distributing data between multiple disks is not possible like huge databases.

Enhanced Security with Restricted Shell Access: This will improve the security posture of Nutanix AOS with,

  1. Ability to freeze the security configuration and settings through Nutanix Command-Line Interface (nCLI). You must contact Nutanix Support to unlock the security configuration to allow for changes.
  2. Optional feature that imposes certain restrictions on the “nutanix” account access to the nCLI and encourage the usage of “admin” account for basic administrative workflows.

Optane Tier for NVMe: In an all-NVMe configuration having Intel Optane drives, Intel Optane is tier 0 and part of ILM multi-tiering architecture. AOS will migrate the random data read with high frequency (read-hot random data) to the Optane performance tier since Optane drives provide very low read latency. 

Dark Theme on Prism UI: Dark Theme in the UI sets a dark background with high contrast view of the Prism UI background.

Whole Node Maintenance Mode: Now Prism Element has the feature to enter/exit a node in and out of maintenance mode with all the VM migration and/or power actions workflow.

VM Centric Storage Policy: Through Prism Central this feature will let you manage the storage attributes like encryption, compression, and QoS for VMs running on AHV clusters by categories.

Space Reporting Enhancements in Storage Summary Widget: The Storage Summary Widget now shows the Total Used Capacity for the snapshots (in GiB or TiB) and resilient capacity of the cluster.

NGT Windows Performance Monitor (perfmon) Integration: This feature provides the ability to monitor the hosts specific metrics for a VM in a guest VM running the Windows OS. The supported metrics are fetched from the CVM and are published to the Microsoft Windows Performance Monitor (Perfmon) utility on the guest VM after the NGT metrics collection is enabled on the UVM.

Support for In-place Entity Restore with Leap Recovery Points:  In-place restoration enables you to restore guest VMs with the same properties like UUIDs, network routing, MAC addresses, hostnames as that of the original guest VMs, and therefore maintain the operational workflow.

Support for Microsoft Windows Server 2022: AOS 6.1 supports guest VMs running Microsoft Windows Server 2022.

Enhanced Cluster Expansion Capabilities: AOS now supports concurrent requests for node preparation and expand the cluster. configuring node networking information, storing network configuration settings, and specifying whether a node should be a hyperconverged (HCI) or storage-only node.

Network Segmentation Enhancements: These will enable to configuring Backplane IP Pool, Enabling Backplane Network Segmentation on a Mixed Hypervisor Cluster, Updating Backplane Portgroup, IP Address Customization for Each CVM and Host, Enabling Physical Backplane Segmentation on Hyper-V.

Removing Multiple Nodes from a Cluster: Now AOS allows you to remove multiple nodes from a cluster.

Support for Storage only Nodes When Expanding Clusters: AOS 6.1 introduces the option to choose Storage only nodes during the expand cluster.

Support for Restoring Network Configuration during Host Break-fix: Now you can store cluster-wide network configurations at regular intervals or on-demand. The stored network configuration can be used to restore a node to the same configuration in break-fix scenarios.

Additionally few Volume Group Enhancements, PagerDuty Integration with Prism, New CHAP Algorithms for Volumes, along with bug fixes and security patches.

Prism Central 2022.1

Category-based Host affinity policy: This feature will enable VM-Host affinity policy in Prism Central using categories. This feature will let easily manage affinities for a large number of VMs.

AHV VM templates: This release introduces the VM templates feature for AHV VMs. The feature enables you to create and manage a master copy of a VM that you can use to deploy multiple VMs across clusters. A template includes the guest operating system, VM configuration (that may include multiple disks), and all the applications installed on the VM. You can maintain multiple versions of a template. The feature also enables you to upgrade the guest operating system of the template.

Storage Container Management: This feature extends the existing storage container management in Prism Element to Prism Central. The functionality helps the users to create, update, delete the Storage Container through Prism Central.

Along with Dark Theme on Prism UI, Categories Services, Nutanix V4 API Versioning, Utility Actions Enhancements, Ownership of Restored VM from Recovery Point and along with bug fixes and security patches.

As always go through the release notes and documentation before upgrading cluster AOS and Prism Central.
