Nutanix AHV

Nutanix AOS makes the basic operations (adding recourses and performing updates) a lot easier.

50/50, not much in it, to be honest. Nutanix AOS wins on the support, training, and certification ease but Dell / EMC has the name and integration support with its other products (e.g., Nutanix not supporting Networkers hot add mode).

By far, in my opinion, Nutanix AOS is heads above VMware. From the creation of a VM to updating the nodes themselves, Nutanix AOS is so much easier, faster, and just an overall better product. I would choose Nutanix AOS over VMware any day.

Vmware , Cisco HyperFlex

VMware ESXi has been around much longer and because of this is much more fully featured. However, on the flip side, it then makes Nutanix AOS much less complicated to operate. Nutanix AOS online support (and knowledge base articles) are very well written and comprehensive. The VMware support site is more complicated to navigate.

Nutanix [AOS] is a hyper-converged solution, and in the vSphere it was originally designed for the use of SAN, although they also have a hyper-converged solution. But the architecture and load testing showed the inconsistency of the hyper-converged solution from VMware.

Nutanix [AOS] is the preference as it has good management tools but may be a bit more costly.

The simplicity of the license means no need for a new storage array and hardware. Gartner report.

Nutanix is faster and easier, and more reliable than HPE SimpliVity.

As mentioned before I feel that Nutanix meets or exceeds the capabilities of the competition, where that is in ease of use, how well they support their platform, upgrading software, migrating VM's from another hypervisor to Nutanix or simply moving VM's between one Nutanix cluster to another cluster, the performance and support has always been great.

VMWare is too complex to run in compare to Nutanix

Ease of use and better support to the business.

Nutanix AOS is far superior to VMware. Both in cost and performance.

There are other clustering solutions, to be sure. And there are significantly less expensive solutions for preventing downtime, such as Hyper-V replication, which is what I was using before Nutanix. But Nutanix is in the upper-right of the Gartner magic quadrant for hyperconverged solutions. If you want an all-in-one solution that comes highly rated by industry experts, it can be a great way to go. It was also selected because several peers had selected it and had good experiences. I've used Hyper-V (which you can run on Nutanix instead of AHV, by the way, although you lose many of the cool features AHV offers) and VMware (which you could also run on Nutanix), I have not found myself wholly missing either of those products by using AHV.

VxRail was more expensive and used a different storage algorithm that we didn't find to be most efficient .

We looked at both Simplivity and Cisco HyperFlex. Both are pretty good in their own right. Simplivity was very 'efficient' in the way they handled data, but we didn't like the idea of a propitiatory hardware card. Cisco's HyperFlex was our second choice, but we were so impressed with what Nutanix had done for us already, that we were already leaning toward that.
