Nutanix CE is Now Available to All and it’s FREE!

Nutanix CE is a great way to get you started with Nutanix in your own lab environment; and it is now available to everyone now. CE is a fully working Acropolis + Prism stack that enables you to not only host your virtual machines, but enjoy all the benefits of Nutanix. The features available with CE are the exact same enjoyed by paying customers, being the difference that it is a community supported edition and there is a maximum limit of 4 nodes.

Some of the features available with CE are:

  • De-duplication
  • Compression
  • Erasure Coding
  • Asynchronous DR
  • Shadow Cloning
  • Single server (RF=1), three servers (RF=2) or four servers (RF=2)
  • Acropolis Hypervisor (all VM operations, high availability etc.)
  • Analytics
  • Full API framework for development, orchestration and automation
  • Self-Healing
  • ToR integration

Metro Availability, Synchronous Replication, Cloud Connect and Prism Central as not part of Nutanix CE.


Since you will be providing the hardware there are some minimum requirements:

Nutanix CE extends the Nutanix commitment to fostering an open, transparent and community-centric approach to innovative solutions for mainstream enterprises. Nutanix CE enables a complete hyperconverged infrastructure deployment in just 60 minutes or less on your own hardware and without virtualization or software licensing.

To get started access the Nutanix Portal, create an account and you will be able to register for download. The first batch of public users are already receiving their license keys. Alternatively follow this link to apply for a Nutanix CE license..

Also, make sure you check out all the Nutanix CE blog posts authored by the community on the Nutanix Index.

NOS 4.1.3 – What’s New!

Nutanix will soon be making available the NOS 4.1.3 release. This release has major enhancements for the areas of storage optimization, disaster recovery and management. Let’s go straight into the new features and improvements.


  • Erasure Coding

Erasure coding offer significantly higher reliability than data replication methods at much lower storage overheads. Erasure coding has been traditionally implemented using RAID groups on disks; however those are commonly bottlenecked by single disk, constrained by disk geometry and generally waste space implementing hot spared. Nutanix EC is a Next-Gen Storage Optimization done across nodes instead of disks, optimizing availability with faster rebuilds and utilizing the entire cluster through map-reduce processes to compute block parities. Read more in my article New Nutanix Erasure Coding & How it works?


  • Sync Replication

Sync Replication is used for planned and unplanned events where no data loss (0 RPO), as little downtime as possible (~0 RTO) and non-disruptive site migrations are required. This may include site outages, natural disasters, hardware maintenance, workload migration and disaster avoidance scenarios.

The major different between Metro-Availability and Sync replication is that organizations do no require a stretched vSphere cluster between two or more sites; therefore not requiring layer-2 extensions and overlays.

With Synchronous DR the migration workflow can be scripted and customizations may be added to the flow; however for metro-availability we would be looking for heavy automation with very little workflow customization; such as changing IP addresses etc.

Finally, Sync Replication will work with vSphere and Hyper-V; following by Acropolis in the following release. Metro Availability is only supported with vSphere today.

I’ll soon write more about Sync Replication.


  • In-guest iSCSI Support

Nutanix now offers the ability to natively mount Nutanix vdisks into Windows guests via the Windows iSCSI adapter. In the VMware would like to have the ability to mount a vmdk via the Windows iSCSI adapter.

The use cases relate to supporting applications that don’t provide NFS support; such as Microsoft Exchange or Windows Guest Failover Clustering.


  • ToR Visibility

Host networking is already part of the Nutanix architecture and is managed by Acropolis (the new control plane); however Nutanix is now extending networking management and monitoring to the entire network stack in your datacenter. Tor integration with Nutanix offer auto-discovery using LLDP and SNMP; and focus on providing visibility of the networking stack via the Prism interface. Furthermore Nutanix announced OpenDaylight integration over the next couple releases. Read more in my article New Nutanix ToR Switch and OpenDaylight Integration.


  • Acropolis Image Service and HA

Pre-4.1.3, users of Acropolis hypervisor had no single command to download and covert disk and ISO images to a Nutanix cluster, nor a way to manage a library of existing images. NOS 4.1.3 introduces the ability to upload disks and ISOs from external HTTP/NFS servers while providing an integrated method to dynamically convert disk images from various formats to raw flat disks on NDFS.

Pre-4.1.3, VMs running on Acropolis hypervisor did not have automatic HA to protect against host failures. Nutanix HA automatically restart VMs on another host upon failure. HA may be configured as “Reserved Capacity” or “Best Effort” policy. The HA protection is set on a per-VM basis allowing the administrator to choose how to best implement protection.

Introducing Nutanix App Framework!

As part of the PRISM framework Nutanix will be launching an application framework and SDK that allow partners and developers to build their own PRISM applications using Nutanix infrastructure and VM collected datasets and/or third-party data via the use of APIs. Apps can be developed using JavaScript for the web front-end, but they can also have server-side components running on node.js or any scripting language such as python; or even other development frameworks.

The architecture is completely based on containers providing complete abstraction and segmentation between applications and core Nutanix code and datapath. Nutanix engineering is making containers really easy to be consumed by developers and by administrators, and I will soon be able to discuss a little bit more about that. The overall concept includes the ability to automatically download integrated applications from a Nutanix App library.

The types of applications that can be built to be included in the Nutanix App library are limitless, including 3D modeling, reporting, workflow, root cause analysis, alerting, and even games using the Nutanix dataset. Watch the videos below to understand the types of apps that can be built using the framework.


To prove that anyone can build something useful I put my coding skill in practice and built an app that provides API integration with Liquidware Labs to analyze and monitor the VDI user experience as measured by Liquidware Labs Stratusphere UX. Have a look!


These are simple examples, but advanced workflow engines and integration with enterprise applications for data correlation is also possible. The Nutanix Prism app framework is still under development and has no definitive date to be generally available yet.
