AOS integrates storage, compute and networking resources into a scalable, secure, resilient and easy-to-use software-defined infrastructure.Please review the release notes before deployment for all productsHere are some highlights from the AOS 6.1 release.New and Updated Features | AOS 6.1Improved Single vDisk PerformancePreviously, the vDisk controller employed just a single thread for each vDisk. Now, the vDisk controller can spawn multiple sharded controllers (up to 4) to create a multithreaded environment for processing application requests (reads and writes). From the application perspective, there is still a single vDisk controller, but the actual workload is multithreaded. The multithreading can result in substantial performance improvements for applications that use a single large vDisk, such as certain database applications. The multithreading can also provide performance improvement for multiple vDisk applications.Enhanced Security with Restricted Shell AccessRestricted Shell Access improves the security posture of Nutanix AOS with the following controls: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..Dark Theme on Prism UIThis feature extends the Prism themes feature to support a darker theme. Selection of the Dark Theme in the UI sets a dark background with high contrast view of the Prism UI background. The UI changes cosmetically to reflect the selection. See Modifying UI Settings in the Prism Web Console Guide for more information.Whole Node Maintenance ModeThis feature provides the ability to gracefully handle the node maintenance for planned outages. With this feature, the existing node maintenance procedure from the Acropolis Command-Line Interface (aCLI) is now extended to the Prism Element web console. When a host is placed in the maintenance mode, the CVM is placed in the maintenance mode as part of the node maintenance operation. The non-migratable VMs (for example, pinned or RF1 VMs which have affinity towards a specific node) are powered-off while live migratable or high availability (HA) VMs are moved from the original host to other hosts in the cluster. After exiting the maintenance mode, all non-migratable guest VMs are powered on again and the live migrated VMs are automatically restored on the original host.VM Centric Storage PolicyStorage Policies in Prism Central let you manage the storage attributes like encryption, compression, and QoS for VMs running on AHV clusters. Prism Central allows you to apply storage policies on a per VM basis using Category, so that the VM uses the storage configuration defined in the storage policy. Using a storage policy, you can manage parameters of VMs, such as encryption, type of or lack of data compression, and IOPS or Throughput throttling values to be applied to the entities.Prism Central supports storage policies only for VMs. Storage policy is not supported for Volume Groups (VGs). Prism Central supports storage policies only for entities running on the AHV hypervisor. You can associate one storage policy with multiple categories. However, you can associate one category with only one storage policy.Support for Microsoft Windows Server 2022AOS 6.1 supports guest VMs running Microsoft Windows Server 2022.Note: Since Intel NIC adapters do not have compatible async drivers (third-party vendor drivers certified by VMware) for Hyper-V 2022, NX Series platforms do not currently support Hyper-V 2022 deployments.Removing Multiple Nodes from a ClusterAOS allows you to remove multiple nodes from a cluster. The multi-node removal process is sequential. That is, you can request to remove only one node at a time. However, you can mark other nodes for removal one after the other while data is being evicted in background from other nodes marked for removal.Please review the release notes before deployment for all products

Prism Central is the native control plane user interface unified across multiple Nutanix clusters.Please review the release notes before deployment for all productsHere are some highlights from the Prism Central release.New and Updated Features | pc.2022.1Category-based Host affinity policyThis release introduces the support for defining the VM-Host affinity policy in Prism Central using categories. This feature enables you to easily manage affinities for a large number of VMs. In case of any change (addition or removal) to the list of affined hosts, you only need to update the category of the host and this internally updates the affinity rule for all the affected VMs. The minimum supported versions for VM-Host affinity policy are version 6.1 for AOS and version 2022.1 for Prism Central.AHV VM templatesThis 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.The minimum supported versions for AHV VM template feature are 5.19.2 for AOS and 2022.1 for Prism Central. See Prism Central Guide for more information about the feature.Dark Theme on Prism UIThis feature extends the Prism themes feature to support a darker theme. Selection of the Dark Theme in the UI sets a dark background with high contrast view of the Prism UI background. The UI changes cosmetically to reflect the selection. See Modifying UI Settings in the Prism Web Console Guide for more information.Storage Container ManagementThis 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. The storage containers in Prism Central operate on all instances of the Prism Element registered to the Prism Central, requiring the user to select a cluster during the create operation. See Storage Management in the Prism Central Guide for more information.Please review the release notes before deployment for all products

It’s been a busy week of product updates and improvements. Here is what has been released last week.Please review the release notes before deployment for all productsAOS (STS) 6.0.2.2AOS integrates storage, compute and networking resources into a scalable, secure, resilient and easy-to-use software-defined infrastructure.The release resolves the following critical issue:Prism GatewayResolved an issue where attempts to upgrade to AOS 6.0.2 might stall as the Controller VM eth0 network interface is not available after the Controller VM restarts as part of the upgrade process.AOS (LTS) 5.20.2.1 The release resolves the following critical issues:Cluster ConversionImproved network validation to ensure that the networks that do not have any VMs attached are, by default, retained after an ESXi to AHV cluster conversion. Contact Nutanix Support if you do not wish to retain networks without any VMs. Resolved an issue where during cluster conversion the mapping of the target networks is not properly set to the default virtual switch vs0. Improved the cluster conversion process by running 20 VM conversions in parallel.Data Replication / ProtectionThe retry or backoff logic applied while waiting for stretch data interface resolution is improved to reduce latency and stun times for quiesced snapshots.FlowResolved an issue where stale cache, populated when VM migration happens while Flow is disabled, results in incorrect rules to be programmed. For further details, see KB 12200.Microservices Platform (MSP) 2.3.4MSP is a managed platform based on Kubernetes for managing containerized services running on PC. The lifecycle of MSP is controlled by a service running on Prism Central called MSP Controller. MSP supports various containerized services like IAMv2, ANC and Objects and more services will be on-boarded in future. You must upgrade MSP before upgrading any of these services.Following are the resolved issues in this release:Fixed the issue where Prism Central was not able to reach corp DNS server due to 127.0.0.1 entry in the /etc/resolv.conf file restricting the user to configure FQDN on Prism Central. Fixed the issue where external nameserver were erased from Object VMs post reboot. This could have caused connectivity issues to LDAP, external FQDN, and so on. Fixed the issue where MSP Controller upgrade through LCM darksite bundle failed; however, in the user interface upgrade was seen as successful. Fixed the issue where object data path had seen issue in case of eth0 network down or up case on Objects cluster running 1.0.8 or below versions.Life Cycle Manager Version 2.4.3.3The Life Cycle Manager (LCM) tracks and upgrades both software and firmware versions of all entities in the cluster, completely in-band with Nutanix Prism Element and Prism Central.New Features:Change path for sudo commandFor all references to sudo, LCM 2.4.3.3 replaces the path /usr/bin/sudo with sudoResolved Issues:ESXi precheck failing with UEFIThe precheck test_esxi_bootbank_space verifies that the system has enough space to restart into the Phoenix ISO. Foundation 4.4.1 added the ability to mitigate low bootbank space, so systems that use Foundation 4.4.1 or later disable this precheck. However, if the system uses UEFI, Foundation's mitigation does not work. LCM now enables or disables test_esxi_bootbank_space depending on the detected boot mode.Inventory failing on IntelFixed an issue on Intel systems where inventory sometimes failed with the error Unable to get the fru details. Failed to run payload_info cmd.ESXi systems returning Failed to power on VMs error after updateFixed an issue where LCM treated vSphere cluster services (vCLS) VMs as pinned VMs that LCM needed to restart after an update. ESXi automatically restarts vCLS VMs after a host restart, so LCM was trying to start VMs that had already started, resulting in the observed error.Be sure to share your upgrade experience in the community forums.

Nutanix is excited to announce the release and general availability of Karbon® 2.3 Kubernetes management software! Karbon 2.3 is packed with exciting new features and enhancements, as well as a number of fixes to enhance the customer experience. We will be highlighting a couple of features in this article but for more detailed information check the release notes.Kubernetes 1.20 Support: Kubernetes version 1.20 is now officially supported by Karbon. Users can now deploy this version using the Nutanix® single-click approach and unlock all of the new features that come with this Kubernetes release. Existing Kubernetes clusters can also be upgraded to Kubernetes 1.20.  Nodepools: The resource requirements for workloads on Kubernetes clusters are constantly evolving. Karbon 2.3 allows users to add nodepools to deployed Kubernetes clusters. This allows for node pools to be added with different resource configurations offering more flexibility in scheduling pods on different node types (CPU heavy, memory heavy, etc.). New CSI Version: Karbon 2.3 by default installs the latest Nutanix CSI driver allowing users to consume the Nutanix platform (including Nutanix Volumes™ or Nutanix Files™ storage) immediately after deploying a Kubernetes cluster. The Nutanix CSI driver will use certificate based authentication (when used in conjunction with Karbon), removing the need to store credentials inside the Kubernetes cluster. Dedicated Network for Storage Traffic: Starting from Karbon 2.3 the Nutanix CSI storage traffic can be isolated on a dedicated network. This isolation can be VLAN or physical separation. UI Support for Kubernetes Upgrades: Prior to Karbon 2.3, Kubernetes upgrades were only possible via the Karbon command line interface (karbonctl). Karbon 2.3 now allows users to upgrade Kubernetes versions via the Prism Central™ UI. Security Fixes and CIS Benchmarks: In Karbon version 2.3, we also improved the overall security posture of the Kubernetes stack by meeting a greater number of CIS benchmarks. In addition we released a new Node OS (1.1) version fixing a large number of CVE’s.Sign up for a Karbon Test DriveIf you’re considering deploying Karbon Kubernetes clusters on Nutanix HCI, then take Karbon for a full test drive! The Nutanix Test Drive program puts you in the driver’s seat of Karbon on a live cluster, letting you experience how smooth and simple Karbon makes Kubernetes cluster deployment, storage configuration, and upgrades.Sign up to take a spin!
