Quotes From Members Comparing Nutanix vs VMware vSAN

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
Pros
Prism Central allows managing the cluster from a single pane of glass, and it allows a deeper dive into the solution.They have one of the best technical supports in my experience.Simplified management: It provides us more time to work on other tasks.Nutanix has several unique capabilities to ensure linear scalability.Single click actions is definitely the most important. They were not even aware that they wanted this.Being able to upgrade our entire cluster with the click of a button during business hours with zero downtime has made managing our infrastructure so easy.I can use VMware or Hyper-V license, if I already have. But if I use a similar solution as Nutanix Acropolis hypervisor (AHV) that comes embedded in Nutanix solution, I can manage all my virtual environments with everything I need without spend more money on licenses.Hyper-convergence is the most valuable feature for me as it allows me to scale the hardware according to project requirements.

All the features are working great.The ability to have an HA cluster in the absence of a shared storage device or SAN.vSAN has just one datastore. so customers do not need to think where to put their VMs, how to design the physical disk RAID, the LUN size, the LUN mapping, etc. when they use NetApp/EMC/HDS or other storage systems.vSAN can help customers save on storage system costs, and also save on the human cost.vSAN is easy for deploying and maintenance, so some customers can do service themselves.It is simple to manage, very easy to implement and troubleshoot in case of any failures.Since the storage space is local to the hosts, it reduces the overall response time and improves the performance.The lower skill cost of maintaining it meant that we could do more with the people that we had.

Cons
I would like better integration of XenServer into the AOS and Prism Central.Make it easier to manage.Reduce its power consumption.There is a need is to be able to consume Nutanix storage from outside the cluster for other, non-Nutanix workloads.Native File-Services are under heavy development and Container Services just came out.Nutanix now supports four hypervisors but they are not all at feature parity.AHV is a great hypervisor but still limited compared to VMware. AHV is the one product they must improve.It would be great if it could emulate some of the features that their competitor VMware has, for example port mirroring or Netflow output at hypervisor level.

Only the stretched cluster requires a minor improvement.vSAN does not have online dedup. When opening the inline dedupe, the performance will be lower than off inline.Virtual machines disk size cannot cap more than a single node. For a VDI user, it may not save enough to hold a file server or exchange server on a single node storage space.Some intelligence can be added to the newest version to provide more flexibility between storage tiers.The main problem we had was hardware compatibility, finding the right hardware that was certified.I lose a node in a cluster vSAN, which is also used as a cluster HA. I lose not only the storage part, which is not necessarily serious (depending on the configuration of the vSAN cluster), but on the other hand, I lose also a node of Compute, which can make things complicated quickly.he list of hardware supported should be increased in the future.The only thing I can think of at this time is to improve the performance monitoring and performance visibility within the GUI.

Pricing and Cost Advice
Work close with your InfraTeam and discuss with Nutanix the best way to achieve sizing and price that are right for you.Licensing depends on the features needed.Extra features should not be so expensive. We would love to be able to use or even just try some of the extra features without having to buy them. Buying those features is just as expensive as buying vSphere licenses, so the cost savings is nullified.Setup cost is minor, pricing is quite a bit (we have a 7-node-cluster for about 450K EUR with 2 vGPU-nodes for Citrix) but that includes hardware, software, and support.While cost may seem higher than your traditional 3-tier architecture, you need to look at the bigger picture. You're not just buying hardware here. You're buying a complete environment.I know Nutanix and VxRail have similar prices and licenses. Nutanix is a go-ahead if AHV is used as hypervisor because it is already embedded in the price.The basic license that comes with the box allows basic virtualization features but advanced automation features would require an upgrade of licenses.Able to grow with smaller, more linear increments of investment

​I would like to see this technology be made available to smaller businesses, who might benefit from high availability but struggle with the entry fee.​Perhaps a bundle, like Essentials, would allow more businesses to make the leap to the product.Basically, vSAN is a license in addition to that of the classic VMware Vsphere, which is also mandatory.Its reasonable, compare with other storage vendorsThe first 1-2 years of purchasing vSAN will be expensive. Thereafter, the longer you are running it, the more cost savings you will have.

Please see response below from Shane Hill, PMP Arrow SI Practice Manager, Data Center Infrastructure

vSAN was not originally designed to be a replacement for Enterprise storage systems. It was originally designed as a low cost alternative to them for Small Office Branch Office. It then got dragged kicking and screaming into today because of companies like Nutanix as competition. Even with vSAN R6.6, it’s still got some glaring misses.

* Restricted write buffer size
* Maxiumum number of nodes
* Long rebuild time
* Deduplication/compression/erasure coding are only available with All-Flash
* No data locality
* Only available with ESXi
* Datastores/Disk Groups don’t survive an SSD failure in a hybrid system
* You can’t pin a VM to flash

As far as management goes, Nutanix kills vSAN hands down. In my opinion for 1 big reason. The rest are just icing on the cake. The big reason is one-click upgrades. I can upgrade all the nodes in a cluster by logging into the PRISM interface, choosing upgrade button, hitting download latest button, and hitting upgrade. That’s it. It will do a rolling upgrade of the Nutanix software with zero downtime. Upgrades of the bios, firmware and even ESXi(if you are using it) are done similarly. I upgraded the Nutanix clusters at a major health insurance company during business hours last week. That was 13 nodes in the primary cluster and 12 nodes in their DR cluster during the day without downtime. Now, doing hypervisor upgrades is a little different in that you still have to move the VM’s as each upgrades.

Other things that I love about nutanix.

* Native backup to AWS or Azure
* Self Service Portal- allow a non technical user to deploy a VM. You can even script the SSP to authenticate with Service Now and allow a VM to be created from a Service Now template ticket. That is slick!
* One pane of glass. All management for the AHV hypervisor and the cluster are done from within PRISM. There is even an integration to vCenter so from within the PRISM interface I can do 90% of VM management of ESXi VMs. IE, stop, start, console, edit, etc.
* Integrated tools to allow migration from ESXi to AHV while the cluster is running.
* Can run File Services natively and manage it from within PRISM
* Publish iSCSI block storage to VMs AND bare metal servers outside the cluster. I love this. We use this a lot.

I been using VMware for long time and they have a very robust product that for quite some time. We used vSan to consolidate some low budget storage in order to maximize their use however, We switched to Nutanix seeking performance, flexibility to use both SSD and HDD, Licensing savings and of course one of your questions, the usability and simplicity.

After a year, I do recommend Nutanix because is simple to use (management and processing tasks are far more easy, fast and clean than VMware) , performance and the ability to select which kind of disk I wanted to run my VMs.

Nutanix storage show you a single container for all vms that has the capability of managing I/O loads and prioritize them across disks. In terms of expansion of resources, just adding a new host or storage node will expand the cluster easily. In the case you use DELL XPS server, you can add Disks to each node to expand storage without adding new host (If you have the physical space of course).

Nutanix user interface is clean, already tested in all browsers and their support is fast with a few clicks you can almost do everything. Really fast interface response.

Replication and protection is built in with consistent snapshots and also it has real-time statistics of the health, network, protection and hardware in the same management console. Basically you do everything in the same place.

Migration in Nutanix was a snap, easy and without complications, they had a tool that help schedule migrations without user input that connects to VMWare and migrate and translate all VM needs into the new system.

I use the VMware Client completely because the interaction everyday, I found the Web version not as fast or responsive than the old client and also managing storage between the cluster sometimes get messy, compatibility issues, orphaned snapshots, even sometimes if a host failed, the vCenter Appliance does not respond well restoring the cluster HA sometimes and needed to disconnect, reconnect the hosts in order to make it work.

I do not tested simplivity but I did use this link because I liked how they evaluate each solution:
>> http://www.datacenterzombie.com/hyper-converged-infrastructure-comparison/

I recommend to specifically look at the upgrades section. I already did various 1-click upgrades without production interruption in my Nutanix Clusters in comparison of VMware with HPE where I need to upgrade SAN firmware to fix performance issues and I need to take all the cluster down to perform it and I rather prefer to let HP support (that of course has costs involved) to do it in case something go wrong.

Another good information source ( see Figure 1. HCIS Key Feature Comparison)
here:

>> https://www.storagenewsletter.com/2015/07/08/hyperconverged-infrastructure-solutions-simplifies-midmarket-data-center-gartner/

We been with HP for more than 15 years and we switched to Nutanix hardware because instead of purchasing hardware, Hypervisor software and upgrades, monitoring and alerting software, backup software, basically we got it all from Nutanix tested, built in and ready for function in no time.

This of course is my opinion while using both platforms while I finish the migration of very old databases to the new Nutanix system.

Hope this information helps you.

That depends on many factors and understanding where HCI is going today. The marketecture of HCI would have you believe that architected with hybrid-cloud cloud in mind. For the enterprise, hybrid-cloud will be the new norm.

I think Nutanix has done a remarkable job moving the discussion beyond an HCI to one that includes other things to a point where the Nutanix solution is an OS. As for AHV, it's grown by %25.

On the flip side, VMware has also done a remarkable job in partnering with AWS and others. MSFT now has Azure stack and linux consumption has grown %70. The last man standing without an on prem HCI solution for a hybrid cloud is Google. The Nutanix DNA comes from Google and have signed a unique partnership with them.

A lot of this could come down to, which public cloud makes the most sense for your business. The goal of Nutanix, VMWare and MSFT is to create a single pane of glass of O&A like VRA. Each one can do it today.

But what if you want an HCI multi-cloud solution. Then you may need to consider Cisco C3 and pick the HCI solution of your choice.

I'll admit I am a little biased towards VMware's vSAN. I've been using it since beta in 5.5 and have not had much experience with Nutanix.

To me, VMware is the leader in this space. They might have been late to the game as Nutanix jumped ahead first, but they are quickly gaining traction and have been consistently releasing new features and functionality to their product.

vSAN is baked into the hypervisor at the kernel level, you just turn it on. There are no virtual appliances needed to manage and cluster the storage.

It is my opinion that VMware is the only true hardware-agnostic HCI solution and that everything else is vendor lock-in. You may get a good deal on Nutanix today, but might find it more expensive to scale later on. I've heard stories of customers getting gouged when trying to just add RAM to their nodes. Building your own nodes, starting with vSAN ready nodes will allow you to design a solution that can be scaled up or out.

Also, the VMware hypervisor is very widely used and supported. You will find many more articles and forums with answers to your questions on this platform over Nutanix. Also, there is an ecosystem of products that compliment the VMware solution that may not support the Acropolis hypervisor.

as always, it depends on what you are trying to do and what your requirements are.

With VMware, you have flexibility of choosing your own hardware vendor. VSAN is having lot of new features in the new release. If you prefer NSX then again VSAN.
If you need multi hypervisor environment, then Nutanix.

It is better refer the blogs for detailed comparison before any one take a call.
