Nutanix includes a set of features known collectively as Insights that provides a predictive health and support automation platform. Insights dynamically analyzes the extent to which you are following best practices in configuring your clusters for long-term reliability, availability and performance. Insights provides Predictive trends and analytics Guidance for optimal configurations Application best practices Seamless automation support Insights is available only for clusters with Pulse enabled. Workflow: Pulse collects cluster data and sends it to Nutanix customer support. The pulse data goes to the Insights engine, a SaaS-like service in the cloud, that goes deep analytical processing of the Pulse telemetry and identifies potential issues based on findings or patterns in the data. Insights employs analytics built on historical data and best practices to identify cluster configuration gaps that affect reliability, availability or performance before they become a serious

You can configure a VM to boot over the network in a Preboot Execution Environment (PXE). booting over the network is called PXE booting and does not require the use of installation media. When starting up, a PXE-enabled VM communicates with a DHCP server to obtain information about the boot file it requires. Configuring PXE boot for an AHV VM involves performing the following steps: Configuring the VM to boot over the network. Configuring the PXE environment. The procedure for configuring a VM to boot over the network is the same for managed and unmanaged networks. A VM that is configured to use PXE boots over the network on subsequent restarts until the boot order of the VM is changed. To configure a PXE environment for a VM on a managed network on an AHV host, do the following: Log on to the Prism web console, click the gear icon, and then click Network configuration in the menu. The Network dialog box is displayed. On the Virtual Networks tab, click the pencil icon shown for

Nutanix DR solutions Workflow The following flowchart provides you with the detailed representation of the Nutanix DR solutions. This workflow helps you to understand and decide on which DR strategy is best suited for your environment. This workflow covers all the three DR strategies: Protection Domain based DR Leap (on-prem to on-prem) Xi Leap (on-prem to xi cloud services) DR solutions of Nutanix Nutanix provides disaster recovery in Prism Element Web console with the following Recovery Point Objective (RPO) ranges. Async DR: 60 minutes or greater Scheduled with an RPO greater than or equal to 60 minutes are referred to only as asynchronous scheduled and use full snapshots. Schedules can be configured in terms of hours, delays, weeks and months NearSync DR: Between 1 and 15 minutes Schedules with an RPO between 1 and 15 minutes are called NearSync schedules. In reality, these scheduled are also asynchronous schedules, but they have 15 minute or lower RPOs.

Most of our customers upgrade their infrastructure once every couple of months and this guide helps our customers understand how to upgrade and what to expect from the process. In older versions of AOS, upgrades were done using “one click” or “upgrade software”. With LCM available in newer versions, the upgrades are much simpler and straightforward. Here’s the documentation to understand pre-requisites of LCM and how LCM works:https://portal.nutanix.com/page/documents/details?targetId=Life-Cycle-Manager-Guide-v20:Life-Cycle-Manager-Guide-v20 The LCM works on one-node at a time and if the upgrade proceeds to the next node if the scheduled node is successful in upgrading to the target version. The LCM upgrade tasks can be monitored from “LCM” in Prism UI. There is essentially no downtime required for the user VMs during the upgrades. With regards to concerns about performance, it’s always best to schedule maintenance window for the upgrades, especially with the cluster with 1G NIC ca

Persistent file handles facilitate continuous availability (CA) for SMB shares. During the disruption of service, SMB shares remain continuously available by using the persistent file handles and the high-availability features. Persistent file handles reduce the period of data unavailability by automatically reconnecting users to the file service in-use before the disruption. Files store open lock information on persistent volume groups available for every FSVM in the cluster. During a fail-over, the fail-over FSVM can access the volume group. Persistent file handles let clients wait to reconnect without notifying the user about the connection failure. As a result, disruptions are seamless to users and applications. During a lock protection interval, Files does not prevent NFs clients from accessing the file. Files only prevent SMB clients from accessing files during the disconnected state. The periodic handler cleans up stale locks for the disconnected persistent file handles every 24
You can protect a guest VM either with a protection domain in Prism Element or with a protection policy in Prism Central. If you have guest VMs in protection domains, migrate those guest VMs to protection policies to orchestrate their disaster recovery using Leap Migration from protection domains to protection policies is a disruption process. For successful migration, Ensure that the guest VMs have no on-going replication. Ensure that the guest VMs do not have volume groups. Ensure that the guest VMs are not in consistency groups. To migrate a guest VM from a protection domain to a protection policy manually, perform the following procedure. Procedure: Unprotect the guest VM from the protection domain Do not delete the guest VM snapshots in the protection domain. Prism Central reads those guest VM snapshots to generate new recovery points without full replication between the primary and recovery Nutanix clusters. If you delete the guest VM snapshots, the VM data replicates
