Nutanix 4.1 Features Overview (Beyond Marketing) – Part 1

Today Nutanix announced the first part of a multi-month announcement for NOS 4.1. This release is mostly focused on enhancements for the areas of resiliency, security, disaster recovery, analytics, supportability and management. However, even being a ‘dot’ release, NOS 4.1 delivers very important features, and in my option this version has enough meat to actually even be considered a major release.

It’s been only 5 months since NOS 4.0 was announced with the introductions of Hybrid On-Disk De-Duplication, Failure Domain Awareness, Disaster Recovery for Hyper-V, Snapshot Scheduling, One-Click NOS Upgrade and others. If you missed the NOS 4.0 release announcement read about it at Nutanix 4.0 Features Overview (Beyond Marketing).

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.

Please refer to the product Release Notes for official information from Nutanix.

Let’s start with the New Features…


Data Protection

  • Cloud Connect

Nutanix allows administrators to implement and manage VM centric Disaster Recovery policies across multiple sites and datacenters using a multi-topology architecture.

Whilst the Nutanix built-in DR capabilities allow administrators to specify snapshot retention policies, this approach can be expensive even when data de-duplication and compression are already enabled across cluster. There must be enough storage capacity available to retain the data and be able to handle multiple backups and snapshots over a long period of time.

Nutanix has now officially announced the ability to leverage the global, distributed and highly available infrastructure of Amazon Web Services for data backup and restore. That means that an on-premise Nutanix cluster is now able to back up and restore virtual machines to AWS, while having organizations getting billed directly for AWS for EC2 and S3 costs.


With Cloud Connect organizations are able to schedule, manage and use local and remote snapshots and replication for backup and disaster recovery from within Nutanix PRISM user interface.

  • Local snapshots with Time Stream
  • Backup to Amazon S3
  • Integration with VSS and SRM
  • Quick restore and state recovery
  • WAN-optimized replication for DR
  • Works with ESXi and Hyper-V
  • 15 minute Cloud RPO

Administrators also have the ability to control and fine tune the back-up schedule and retention policies to meet the needs of the workload. The back-up schedule can be as low as 15 minutes or as high as a day enabling you to choose the frequency that best meets the infrastructure capacity and SLAs.

A Nutanix NOS instance (software-only) runs on AWS and each AWS NOS instance is managed as a remote site in Nutanix – it’s all integrated and managed via a single pane of glass. In AWS the remote site will require a M1.xlarge instance and the AWS NOS instance may be created in an availability zone of choice, increasing reliability and resiliency as needed by your organizations. You can have as many AWS NOS instances as needed.

The NOS cluster services run on this AWS virtual instance and uses Amazon EBC for metadata and S3 to storage the backup data. All the communication is done via VPC or SSH tunnels with optimized data transfer de-duplication for both backup and restore operations.  Data is de-duplicated and compressed before it is backed-up in the public cloud with net result savings of 75% in both network bandwidth usage and storage footprint. It is also possible to throttle the network bandwidth consumption of backup to ensure that applications performance is not affected in any way. In addition to that, data transfer throughput with SSH falls by approximately by 25% compared to VPC and is the recommended method.

Just like any other cloud service AWS is subject to failures and outages. For this reason the AWS NOS instance takes automatic periodic snapshots of EBS volumes stores in S3. A AWS failure or unavailability will automatically raise an alert on the on-premise NOS cluster, maintaining that single pane of glass for managing all your Nutanix clusters and instances.

I will soon be working on a video demo to publish here, but in the meantime you can watch this video with Disaster Recovery – Failover and Failback with Nutanix.




  • NX-8150

Nutanix scale-out solution already handles the large majority of workloads using existing NX models, but certain workloads with very large active datasets or write IO intensive can benefit from additional performance. The NX-8150 is the new platform for those Tier 1 business critical workloads and it can be mixed with existing Nutanix clusters.

The NX-8150 is the first platform to fully leverage the Nutanix scalable write buffer, which improves performance and drives down latencies for the most demanding applications. In addition, the larger SSD tier for active data satisfies the latency and IOPS requirements for database workloads, without the excessive cost of an all-flash appliance.

The ability to mix different nodes types into a single cluster makes it practical and easier to eliminate infrastructure silos in datacenters.


The NX-8150 is targeted at Microsoft Exchange, SharePoint, SAP, High performance databases such as MS SQL Server and Oracle RAC; and it comes with 4 times the number of flash devices compared to previous Nutanix platforms to accommodates a much larger active data set. The NX-8150 is also the first Nutanix platform that offer flexible configuration of storage and server (compute) resources from factory, and that include multiple CPU options, 3 different SSD configurations, a variety of memory profiles, and multiple options for connectivity including ability to expand to 4x 10GbE ports.


Another benefit of the NX-8150 platform with flexible configuration is the ability to minimize the number of software licenses (applications and hypervisor) to be purchased. Think vSphere and Oracle.

Tests and validations will soon come out from Nutanix performance and engineering labs. Here is an example of such validations for Microsoft Exchange workloads where using the new platform with only 2U footprint Nutanix is able to manage 6x more mailboxes per node – 3,300+ mailboxes per node following Microsoft testing guidelines and practices - can linearly scale the system to support 100,000s of mailboxes simply by adding additional NX-8150 nodes.


Security and Compliance


  • Data At Rest Encryption (NX-3060-E, NX-3061-E, NX-6060-E)

Nutanix clusters are deployed in a variety of customer environments requiring different levels of security, including sensitive/classified environments. These customers typically harden IT products deployed in their datacenters based on very specific guidelines, and are mandated to procure products that have obtained industry standard certifications.

Data-at-rest encryption is one such key criteria that customers use to evaluate a product when procuring IT solutions to meet their project requirements.

Nutanix Data-at-Rest encryption satisfies regulatory requirements for government agencies, banking, financial, healthcare and other G2000 enterprise customers who consider data security products and solutions. This new feature allow Nutanix customers to encrypt all or selected partitions on persistent storage using strong encryption algorithm and only allow access to this data (decrypt) when presented with the correct credentials.


  • Compliant with regulatory requirements for data at rest encryption
  • Leverages FIPS 140-2 Level-2 validated self-encrypting drives
  • Future proof (uses open standard protocols- KMIP, TCG)


To enable Nutanix DRE a 3rd party key management server is required. At the time of the launch only ESXi is supported and only the SafeNet KeySecure Cryptographic Key Management System is certified, but overtime other key management systems will be supported. Nutanix supports any KMIP 1.0 compliant key management system, but others have not yet been certified. The key management system can even be a VM running on the Nutanix cluster.

Currently it is not possible to mix a Nutanix DRE enabled cluster with a non-DRE cluster because the platform requires special FIPS 140-2 Level 2 SED drives to meet the data at rest encryption requirements. By breaking the homogeneity of the cluster, one will violate the data at rest encryption requirement for copies of data stored on non-SED drives.  However, both DRE and non-DRE cluster can be managed via the same PRISM Central UI.




  • One-Click Hypervisor and Firmware Upgrade

I kinda soft-launched this feature in my article Nutanix One-Click Upgrade now takes care of Firmware and Hypervisor too! after Nutanix CEO Dheeraj Pandey revealed the new feature in a tweet. Love it!

In addition to the already non-disruptive NOS upgrade, the One-Click upgrade feature now ensures that the hypervisor (vSphere and HyperV) is also automatically upgraded in a distributed and rolling fashion. Nutanix is solving a huge problem, where either manual intervention or external automation tools are required.

In addition to the new hypervisor upgrade feature Nutanix is now enabling NCC (Nutanix Cluster Health) upgrade and hardware firmware upgrade. Let’s talks about firmware upgrade.

Upgrading firmware on servers, controllers, disks and other interfaces is probably one of the major pain points for datacenter administrators. The workflow normally goes as follows: schedule maintenance outage, go to the manufacturer website, download correct firmware, flash firmware via web interface or with a Linux cli tool, reboot server, and then repeat this task for every server in the datacenter that require firmware upgrade. It’s complex and lengthy.

Because NOS runs in hypervisor user space Nutanix is able to execute complex firmware and hardware upgrade processes across multiple server components without requiring reboots. Using Nutanix highly distributed parallel processing the One-Click upgrade takes care of firmware upgrade for all disk devices in the cluster with zero impact to virtual machines and workloads. No reboots required, true AlwaysOn!

As a bonus the framework that is serving as the engine for the Nutanix Cluster Health, also knows as NCC, is also part of the One-Click upgrade process.




Keep tuned, Nutanix 4.1 Features Overview (Beyond Marketing) – Part 2 coming soon!

Using Nutanix Java SDK to Create Protection Domains and Add/Remove VMs

In a previous article I demonstrated how to use the Nutanix Java SDK (here) and provided the URL for the Nutanix Code Repository (here). In SampleRestJavaClient I have been implementing and encapsulating methods that make my life easier when automating Nutanix with Java.

I previously included some initial methods such as getVMs, getDisks, getHosts, getContainers, getManagementServers and getProtectionDomains. Today I have upstreamed couple important methods: getAlerts, addProtectionDomainaddVMstoProtectionDomainremoveVmsFromProtectionDomain.

  • addProtectionDomain – add a new protection domain
  • addVMstoProtectionDomain – add virtual machine(s) into an existing protection domain
  • removeVmsFromProtectionDomain – remove virtual machine(s) from a protection domain

App developers would consider automate the creation of a protection domain dedicated to the application with strict backup and replication SLA requirements. As part of the workflow addProtectionDomain and addProtectionDomain methods would be required. After adding VMs to the protection domain the application or script need to define corncobs and replication configuration. I’ll explain the last step in a next blog post.

	 * Method addProtectionDomain
	 * @param protectionDomainName
	 * @param connMgr
	 * @throws BackupAndDrAdministrationException
	public void addProtectionDomain(String protectionDomainName,
			ConnectionsManager connMgr)
			throws BackupAndDrAdministrationException {
		final BackupAndDrAdministration bcdr = connMgr
	 * Method addVMstoProtectionDomain
	 * @param vMs
	 * @param protectionDomain
	 * @param setAppConsistentSnapshots
	 * @param setConsistencyGroupName
	 * @param setIgnoreDupOrMissingVms
	 * @param connMgr
	 * @throws BackupAndDrAdministrationException
	public void addVMstoProtectionDomain(String vMs[], String protectionDomain,
			Boolean setAppConsistentSnapshots, String setConsistencyGroupName,
			Boolean setIgnoreDupOrMissingVms, ConnectionsManager connMgr)
			throws BackupAndDrAdministrationException {
		final List<String> list = Arrays.asList(vMs);
		final AddVMsToPdRequestDTO vMsToPd = new AddVMsToPdRequestDTO();
		final bcdr = connMgr
		bcdr.addVmsByNamesToProtectionDomain(protectionDomain, vMsToPd);

	 * Method removeVmsFromProtectionDomain
	 * @param vMs
	 * @param protectionDomain
	 * @param connMgr
	 * @throws BackupAndDrAdministrationException
	public void removeVmsFromProtectionDomain(String vMs[],
			String protectionDomain, ConnectionsManager connMgr)
			throws BackupAndDrAdministrationException {
		final List<String> list = Arrays.asList(vMs);
		final bcdr = connMgr
		bcdr.removeVmsFromProtectionDomain(protectionDomain, list);

Please note that the code published in this blog post has also been uploaded to the SampleRestJavaClient repository in GitHub. To execute the methods:

		 * Stablish connection with PRISM API
		final ConnectionsManager connMgr = ConnectionsManager

		 * Add a protection domain
		connMgr.addProtectionDomain("ProtectionDomainName", connMgr);
		 * Add VMs to Protection Domain
		 String VMs[] = new String[] { "vmName" };
		 connMgr.addVMstoProtectionDomain(VMs, "protectionDomainName", false, null, false,
		 * Remove VMs from Protection Domain
		 String VMs[] = new String[] { "vmName" };
		 connMgr.removeVmsFromProtectionDomain(VMs, "protectionDomainName", connMgr);

Nutanix, Software Defined Storage Players and My VMworld Sessions!

I should be on leave this week in preparation for the marathon during next two weeks, but I am not. I am rather working furiously on a number of different Nutanix partnerships and announcements. BTW – Big Nutanix announcement coming sometime next week. Next week is also the Nutanix SKO ‘Sales KickOff’ and this time it’s happening in Vegas at they ARIA. I hope I get some recovery time over the next weekend because right after Nutanix SKO is that time again, VMworld. As always VMworld will happen as if it was a blur… so many conversations, interactions, sessions and parties. It’s always nice to see friends and colleagues that otherwise I would only communicate via twitter and email.

Nutanix is coming big for this VMworld. The Nutanix party seems to be the party that people are looking forward the most. Unfortunately tickets are sold-out with over 1,000 people attending the party. Since it’s sold-out I will not talk about the party, but if you signed-up I hope to see you there. Quick-tip – clever ones apparently ended up scoring tickets.



Nutanix is also giving away fantastic prizes, including an awesome Emperor home office/gaming chair with three 24″ monitors, Xbox One, Two Xbox One wireless controllers and Xbox One chat headset worth approximately $20K. Check it out here how to win!



Software Defined Storage is the HOT topic for this VMworld, followed by Software Defined Networking. I expect to see announcement in these two areas by VMware and many of the partners and players in this market. It’s all good stuff and often times its good for customers when there’s cooperation and coopetition. It’s all good, everybody wins!

In this spirit I am of the opinion that if you are looking for a SDS solution you should check all your options and make the best choice for your organization, while thinking about budget (CAPEX and OPEX), simplicity and management, technology leadership in the SDS space, long term relationship, hardware dependency, and any other aspects you believe are important for your business. So, if you want to learn why not every SDS and hyper-converged solution is built equal here are the technical sessions you should attend.

STO1279 – Virtual SAN Architecture Deep Dive (VMware VSAN)

This session will cover the architecture of Virtual SAN (VSAN) and the technical details of the various functional components of the product. You will learn about VSAN’s clustering and scalability properties; about the algorithms used to distribute data across the cluster so as to meet the availability and performance requirements of applications; about the distributed protocols utilized to guarantee data availability and integrity under any combination of component failures. You will hear how VSAN achieves all that while consuming very low CPU and memory resources on ESXi hosts. The session will also highlight the integration of VSAN with the rest of vSphere, including features such as HA, DRS, (s)vMotion, vSphere Replication and many more.
