VStore refers to a separate mount point that is created with its own NFS namespace in a storage container. VStore Protection DomainThe namespace of a VStore is mapped to the protection domain when you protect the VStore. Such a protection domain is termed as VStore protection domain. A VStore protection domain allows you to protect the VStore. You can also unprotect the protected VStore. Files in a protected VStore are replicated to a remote site at a defined frequency. You can recover these files from the remote site in the event of a disaster. A Nearsync replication schedule of as little as 20 seconds to protect a VStore can be configured. VStore Mapping for Data Protection Nutanix recommends mapping the VStore container in the primary site to a container in the remote site. If a container containing a protected VStore in the primary site is not mapped to a specific container in the remote site, the container in the primary site is automatically mapped to the default (Self-Service) c
I have 5 nodes equipped with 2*3.2TB NVMe SSD and 6* 1.92TB SATA SSD. of every one. all nodes are connected with 25Gb network. all nodes upgarde from AOS 5.15 to 5.20From the nutanix bible, in the scenarion with NVMe SSD + STATA SSD, the oplog will only reside in the NVMe SSD, and not in SATA SSD.So that is mean all the random write will first write in NVMe SSD and then drain to all the NVMe SSD+ SATA SSD?all the sequential write will pass OPlog and only writhe to extent store parally in all NVMe SSD + SATA SSD? How about the read I/O path? In some test, I found that when I do some I/O operation in VM, All the device (NVMe and SATA) have I/O counters and the IOPS are roughly the same in the prism-hardware--disk page. Seems the fast speed of NVMe SSD cannot be utilized.Does you have any suggestions to prove the fast performance improve by used NVMe in the nodes.I also checked that the disk status, as the folloing: It is used SPDK.================== 126.96.36.199 =================Slot D

For a node to join a Nutanix cluster, it must have a hypervisor and AOS combination that Nutanix supports. AOS is the operating system of the Nutanix Controller VM, which is a VM that must be running in the hypervisor to provide Nutanix-specific functionality. Find the complete list of supported hypervisor/AOS combinations at https://portal.nutanix.com/page/documents/compatibility-matrixFoundation is the official deployment software of Nutanix. Foundation allows you to configure a pre-imaged node, or image a node with a hypervisor and an AOS of your choice. Foundation also allows you to form a cluster out of nodes whose hypervisor and AOS versions are the same, with or without re-imaging. Foundation is available for download at https://portal.nutanix.com/#/page/Foundation.If you already have a running cluster and want to add nodes to it, you must use the Expand Cluster option in Prism, instead of using FoundationNetwork requirementsWhen configuring a Nutanix block a set of IP addresses

In Nutanix cluster, Life Cycle Manager (LCM) is used to track current software and firmware versions of all entities in a Nutanix cluster and is also used to perform certain software and firmware updates on this cluster. It consists of a framework and a set of modules for inventory and update. In order to fetch these modules, LCM connects to Nutanix Portal (download.nutanix.com) URL by default. However, in scenarios where the Prism Element (PE) cluster has no direct access to the internet, default Nutanix Portal URL option cannot be used for LCM since it depends on internet connectivity. In this case, prior to LCM 188.8.131.52 version, the only available option was to set up a local dark-site web server so that LCM can pull software/firmware bundles from this dark-site web server. However starting with LCM 184.108.40.206 version & above, LCM allows direct ingestion of certain software/firmware bundles using the 'Direct Upload' option in LCM. So, if you are at a dark site where the cluster does

To replicate entities (protection policies, recovery plans, and recovery points) to different on-prem availability zones (sites) bidirectionally, pair the sites with each other. To replicate entities to different Nutanix clusters at the same site bidirectionally, you need not pair the sites because the primary and the recovery Nutanix clusters are registered to the same site (Prism Central). Without pairing the sites, you cannot perform DR to a different site. To pair an on-prem site with another on-prem site, perform the following procedure at both the sites.Procedure Log on to the Prism Central web console. Click the hamburger icon at the top-left corner of the window. Go to Administration > Availability Zones in the left pane. 3. Click Connect to Availability Zone.Specify the following information in the Connect to Availability Zone window. Availability Zone Type: Select Physical Location from the drop-down list.A physical location is an on-prem availability zone (site). To

Xi Infrastructure ServiceAlong with the infrastructure required to support the recovery of on-prem applications, Xi Cloud Services provides the functionality that you require to run the application in the cloud until you can perform a failback. This functionality, made available as Xi Infrastructure Service, is designed to enable you to address application scaling requirements when the primary availability zone is being recovered from a disastrous event.The configuration tasks described here are specific to Xi Cloud Services. To perform on-prem infrastructure tasks, such as VM and category management, you must continue to use the on-prem Prism Central instance. For information about these tasks, see the Prism Central Guide. Entities MenuThe entities menu provides access to all the entities in Xi Cloud Services. An entity is an object type such as a VM, image, floating IP address, or virtual private cloud (VPC). Virtual Private Cloud Management Floating IP Addresses Management Vir
Prism Central (PC) administrators with the "Prism Admin '' role have full access to Karbon and its functionalities. Performing most karbonctl operations requires admin privileges. PC admins that do not have the "Prism Admin '' role (Cluster Admin and Viewer) can only access Karbon to download the kubeconfig and cannot perform any other administrative tasks. See "User Management" in the Prism Web Console Guide for steps on assigning roles.Nutanix requires configuring Karbon users for a directory service in Prism. See Security Management in the Prism Web Console Guide for directions on configuring a directory service.After setting up and testing your cluster, configure role-based access control (RBAC), see Kubernetes documentation for reference. Accessing Locked nodesKarbon protects all nodes in a cluster. You can access nodes in a Kubernetes cluster using an ephemeral certificate, which expires after 24-hours. Perform the following steps to get a certificate. Procedure In the Clusters
Nutanix Clusters delivers a hybrid multi cloud platform addressing the pressing need for a single platform that can span private, distributed, and public clouds so that you can manage your traditional and modern applications using a consistent cloud platform.Nutanix Clusters has features such as operational simplicity, seamless application mobility, and cost efficiency needed to run applications in private or multiple public clouds and reduce the operational complexity of migrating, extending, or bursting your applications and data between clouds.Nutanix Clusters extends the simplicity and ease of use of Nutanix hyperconverged infrastructure (HCI) software as well as the full Nutanix stack to public clouds such as AWS.You can modify, update, display, hibernate, resume, and delete Nutanix clusters running on AWS by using the Nutanix Clusters console. Nutanix Clusters console Updates The service that is responsible for provisioning, maintaining underlying infrastructure and making confi
You can add a cluster name or virtual facing IP address at any time. To create or modify either value, do the following: Procedure:In the main menu, either click the cluster name at the far left or click the gear icon in the main menu and then select cluster details in the Settings page. The cluster Details window appears. It displays the cluster UUID (Universally unique Identifier), ID and incarnation ID values, along with the cluster name, virtual IP address and iSCSI data services IP address (if configured). The cluster ID remains the same for the life of the cluster, but the incarnation ID is reset (typically to the wall time) each time the cluster is re-initialized. Enter (or update) a name for the cluster in the Cluster Name field.The default name is simply Unnamed. Providing a custom name is optional but recommended. Enter (or update) an IP address for the cluster in the Cluster Virtual IP Address field.A Controller VM runs on each node and has its own IP address, but this f
Hi,Does anyone use One-Click for rolling ESXi patching where you apply patch bundles, i.e. many patches at once? Using One-Click for an upgrade or applying a single patch is documented and discussed/known, i.e. when you need to apply a single file. I’m specifically interested in patch bundles. Like just now VMware released a bundle of 10 patches for 6.7. Making 10 rolled updates via One-Click for each patch is impractical. While applying via VUM does it fine, but due to manual CVM shutdown, it can only be done manually host by host, watching Prism for Data Resilience to return, hence taking time.I’ll appreciate if you please share you approach to this.Thank you.
