New PRISM Central One-Click Upgrade and One-Click Smorgasbord!

The Nutanix One-Click upgrade takes care of NOS, hypervisor, disk firmwares, the NCC and now it also takes care of PRISM Central. That’s pretty much everything in your virtualization infrastructure; but the networking stack.

As the name says, it’s a One-Click upgrade for the entire Nutanix cluster. Nutanix one-click upgrade automatically indicates when a new component version is available and it will auto-download the binaries if the auto-download option is enabled. The component upgrade process uses a highly parallel process and restart one component at the time using a rolling upgrade mechanism. The entire cluster upgrade can be fully monitored by the administrator.

During the upgrade process the AutoPathing feature kicks in redirecting VM I/Os on that node to different node. This has several benefits, including allowing administrators to upgrade NOS, disk firmware and NCC without disruption. The AutoPathing prevents performance loss during rolling upgrades minimizing I/O timeout by pre-emptively redirecting storage traffic to other nodes. Failover traffic is automatically load-balanced with the rest of the cluster based on node load.

The new PRISM Central now also uses the same One-Click upgrade technology. If you still don’t know what PRISM Central does… Nutanix PRISM Central is a single-stop shop for every Nutanix administrator. PRISM Central consolidates all Nutanix clusters across all data centers into a single intuitive user interface that combines information about storage, hypervisors and VMs; a single-pane-of-glass to manage multiple data centers. PRISM Central prevent administrators from having to sign individually to every Nutanix cluster while providing aggregated cluster health, alerts and historical data. Administrators are effectively able to manage all Nutanix clusters from the same user interface.

How I configured my Nutanix Cluster for Synchronous Replication

Now that NOS 4.1.1 is generally available I decided to make some time to upgrade my two production clusters to the latest release and enable metro cluster availability (synchronous replication). Given that I was already at the job I started ScreenFlow for Mac and recorded the configuration steps for the setup. I have never seen synchronous replication that simple before.

NOS 4.1.1 is Now Available to All Nutanix Customers…

Today Nutanix is releasing the most waited NOS release thus far, and it is available for download and install by all Nutanix customer via the One-Click NOS Upgrade. This release is focused on enhancements for the areas of resiliency, security, disaster recovery, analytics, supportability and management.

This is the power of software-defined architectures, running on standard x86 hardware, with no special purpose machine doing one and one thing only. The software approach allows for faster release cycles and whenever there are hardware performance improvements you get to enjoy the benefits and performance improvements right away.

Here are some the new features customers are getting right away:

  • Cloud Connect – Prism UI configuration of Cloud Connect for replicating VMs to Amazon Web Services
  • Data at rest encryption with self-encrypting drives (ESXi only)
  • Hypervisor upgrade from Prism UI (ESXi, Microsoft Hyper-V, and KVM)
  • One-click upgrade for NCC utility
  • Metro availability enabling continuous availability of VMs across two geographically separated sites
  • STIG compliance for Controller VM
  • Support for Prism Central on Hyper-V
  • Nutanix SCOM management pack enables monitoring of Nutanix components (both software and hardware) from the Microsoft System Center Operations Manager console.
  • Nutanix plugin for XenDesktop enables per-VM SLA configuration from the XenDesktop management console
  • Prism Central Scalability improved to support up to 1000 clusters and 10.000 VMs (ESXi, Microsoft Hyper-V)
  • Volume Shadow Copy Service (VSS) support for Hyper-V hosts
  • Simplified and improved certificate replacement in the Prism web console to support Certificate Authority-based chains of trust and the ability to generate self-signed certificates in the web console


For additional information I recommend reading my article All Nutanix 4.1 Features Overview in One Page (Beyond Marketing) or downloading the Release Notes 4.1.1 from the Nutanix Portal. Additionally, to read all technical articles published on NOS 4.1 and NOS 4.1.1 go to the Nutanix Index.
