What is best for use with vSphere 7: VxRail or Nutanix nodes?

Hey peers,

The purpose is academic - we want to install GPU cards to test automation with access to vGPU. 

Thank you!

I don't know the technical details, but if you want to work with the VMware hypervisor it would be best to select the VxRail platform, which is a part of Dell and VMware.


The Nutanix platform would be the option to select if you are thinking of changing the VMware hypervisor for the Nutanix Acropolis hypervisor, which, besides working very well, has no cost and could represent savings to the customer.

Ok, I have no hands-on with vxRail. 
But we have vGPU running on Nutanix with ESXi (vsphere). I am not aware of something like vGPU sharing across nodes/hosts. You did not mention which solution you have in mind as you would be about to choose in the process.


We have Citrix XenDesktop running. It works really smoothly most of the time. We only encountered a lagging problem once every few weeks which we are yet to solve. Perhaps something running in the back of our net.


With Nutanix you would have a solid base to work with.


You did not mention what automation is to be used. You could use something like Nutanix Calm as an automation solution.

Let me know which platform you have in mind to narrow down suggestions.

"Nutanix node you will be running vSphere on top on the underlining Nutanix software" This description is incorrect. 


There is no "layer" between the hardware and the OS which is ESXI hypervisor on both cases.

While both systems do a very good job within the nodal limits for scaling a compute environment - it is the networking layer that has the most impact on GPU sharing across a cluster.  From a practical perspective, VxRail nodes will typically offer a discount over native Nutanix nodes.  With Nutanix you also need servers, disk, networking and GPU's.  VxRail will be more integrated with sized nodes, Dell, Cisco or other networking and often the VSphere 7 licenses can be integrated - achieving a lower net cost.  


Testing for optimizations on either VSAN or Nutanix to see which favors a vGPU system would be something I would like to see quantified.  My guess is they are network constrained and differences between VxRail and a build your own Nutanix environment will be negligible for the same network.  Would be good to confirm if there is an optimal point - say 40Gbps vs 10Gbps or 100Gbps for the inter-GPU message passing.

Best option for vSphere 7 is the VxRail as it designed on VMware technology and built in integrates with vSphere, on a Nutanix node you will be running vSphere on top on the underlining Nutanix software.

Hi community, I work as a System Engineer at a large Financial Services company (size: 1000+ employees). Currently, I've been looking at the following HCI solutions: Nutanix Acropolis AOS and VMware vSAN.  Which of them would you recommend to my company? Otherwise, should I explore any alternative enterprise solution? Please let me know why. Thanks in advance for your help!

Hi.  We have deployed VmWare vSAN to some of our customers. The advantage with VmWare vSAN is that the vSAN software is integrated in ESX. So, you do not need to deploy virtual SAN as VM's. But you need a Witness VM, wich is a virtual ESX - so it will appear as two machines - little confusing in the beginning.  For small deployment (ROBO), you can have a two node cluster, with vcenter installed on the vSAN. This is a cost-effective solution. But keep in mind, the HCL from VmWare - all hardware has to be approved (on the vSAN Hardware Compability List). We have also been searching for a solution to replace the EOL HPE VSA (StorVirtual). Here we came across StoreMagic SvSAN - we have deployed this to a Hyper-V customer. It also runs on VMware vSphere. This is also a brilliant solution and very cost-effective. The deployment scenario is often ROBO (Remote Office Branch Office), but it can scale up.  In a two-node scenario, you can connect 10Gb Eth direct between the two nodes, for synchronization. This works for both VmWare vSAN and Store MAgic SvSAN.

VxRail provides stable solutions for technical problems while at the same time not being too expensive for a company to invest in. Even if you are working with a limited budget, this platform offers freedom of choice and a number of different options. In contrast, Cisco HyperFlex HX does run on the more expensive side and cannot offer the same level of cost-effective solution. VxRail is able to provide both an ability to upgrade the system with an ever-growing library of resources as well as to provide powerful processors. This is something that I greatly appreciate. Being able to simply add upgrades to the system without necessarily having to worry about the system being bogged down is invaluable. The ability that it provides to apply updates to the system with ease is something worthy of note. If you add this to the fact that VxRail runs on multiple cores at 2 gigahertz or higher, then that means that in terms of ability, the VxRail is difficult to match. In terms of usability, it is hard to argue that VxRail delivers. It is pretty simple and easy to both set up and manage. Once the system is set up, all of the management tools are centrally located to assist in providing ease of use. The Cisco Hyperflex HX Series is both stable as well as reasonably easy to set up. Cisco has a step-by-step program guide that leads you through the process. Once it is set up, it is not prone to glitching or freezing. However, the pricing model that Cisco applies to this product requires users to pay a yearly subscription. This can end up being rather expensive in the long run. Conclusion Both systems offer stable solutions. Ultimately, VxRail is more cost-effective.
