Nutanix AOS 6.1, AHV 20201105.30142 & Prism Central 2022.1 Released

As mentioned previously I usually don’t blog about Nutanix AOS Short Term Support (STS) releases but with the new features and enhancements that comes with AOS 6.1, released 2022-02-24, are just to good to not blog about 🙂

Read more about difference between LTS & STS here.

Take a look at the pretty impressive list below which highlights the most important new features and enhancements:

  • Enhanced Security with Restricted Shell Access – see command references here:
    • Added 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.
    • Added an optional feature that imposes certain restrictions on the “nutanix” account access to the nCLI. The added restrictions encourage the usage of “admin” account for basic administrative workflows
  • AHV VM Templates so you can use a standard VM definition to deploy VMs from across Nutanix clusters. The Template functionality comes with version management capabilities.
  • Improved Single vDisk Performance by including multiple threads, shards, at the back end. Still the disk is only one disk attached to the VM.
  • Intel Optane & NVMe SSD are managed as separate tiers in ILM and read-hot random data will be migrated to the Optane kept until it’s no longer classified as read-hot.
  • Encrypted DR Traffic without VPN
  • Storage container management a Prism Central level
  • VM Centric Storage Policy where you can configure e.g. compression, encryption and QoS.
  • Enhanced fault detection for AHV High Availability which now includes not only heartbeat checks but also checks for:
    • AHV host root file system corruption
    • AHV host read-only boot file system
  • Live Migration of vGPU-enabled VMs across Nutanix clusters
  • Category-based Host affinity policy
  • Add multiple nodes to the Nutanix cluster and also remove multiple nodes from the Nutanix cluster
  • Network Segmentation Enhancements which now includes the following features:
    • 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
  • New CHAP Algorithms (SHA1, SHA256) for Volumes for client running CentOS 8 and later.
  • Support for Microsoft Windows Server 2022
  • In-place Entity Restore with Leap Recovery Points
  • Entire Node Maintenance Mode – Includes both host and CVM. VMs pinned to the host or placed on RF1 container will be powered off. Rest of the VMs will be live migrated to other Hosts.
