We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The Windows-based StarWind GUI is easy to use and understand and integrates seamlessly with VMware's vSphere portal as well.""The StarWind products have enabled our organization to modernize stations where larger and more expensive equipment was not an option.""StarWind vSAN was very easy to integrate into our system and ran flawlessly during our entire use time.""It includes every feature that a traditional SAN offers and so much more.""The most valuable feature is the reliable storage replication, which enables me to create a robust infrastructure to run our business.""It provided the much-needed HA on an extremely low budget.""The instant failover, with vSAN copying data to the second node, allowed for the continuous availability of our applications.""I've had to open a few support cases over the years due to administrator errors, and the support received was top-notch."

"The most valuable features are the user-friendly dashboard and that we don't need to move resources manually when adding new nodes into running clusters.""Nutanix Acropolis AOS is easy to use, integrates with other hardware configurations, and is simple to manage.""It's much easier and faster even when you want to create a server from a template or clone.""The most valuable features are easy cloud administration and management.""It is all-in-one. The compute processing, storage, and network altogether make it convenient. We don't have to have different modules for expansion.""Most beneficial feature is simplicity, ease of use.""One of the most valuable features is the One-Click Upgrade. When I need to update the system, I do it with one click. This product is amazing because everything is easy to manage, from network management to snapshots.""Ability to create multiple VMs."

More Nutanix Cloud Infrastructure (NCI) Pros →

"There are many services that can be directly used which are not available in VMware.""I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses.""The initial setup isn't too difficult."

More Rackspace OpenStack Pros →

Cons
"A better overall view of the different deployments could be beneficial, although this is difficult due to how flexible the solution is.""Perhaps more reporting features on the utilization, usage, and performance of the configured high-availability images and underlying physical disks would be helpful.""The setup and documentation for the installation with the free version could definitely be improved.""They require more media visibility.""StarWind Virtual SAN could benefit from better integration with other tools and technologies, such as backup and disaster recovery solutions.""There should be publicly available tutorials on YouTube or other platforms that help the users to integrate this solution with other platforms, for example.""I'd love to see more clarification for us folks who are smart enough to do some damage yet not smart enough to use CLI.""I would like an automated installation/configuration despite the fact that their service is very collaborative, a customer should be able to deploy the solution by themselves."

More StarWind Virtual SAN Cons →

"Nutanix has a complex infrastructure, we have customers that consider VMware instead. Additionally, the performance could be better.""While their overall Nutanix Bible is good, they are lacking good descriptions for particular scenarios that might be helpful to many users.""Areas for improvement would be the memory setting and the CPU setting reserve features, which are not available on Acropolis. I also feel that the DR solution, the reporting, and the component that is combined with the Nutanix OSP need to be improved.""This solution offers excellent functionality but could use a stronger interface.""In the future, I would like Acropolis to add support for publishing external storage.""I would like them to update their licensing to provide more features with their basic license.""We would like to see a cloud version of Acropolis AOS. Currently, we're trying to implement an AWS environment for some solutions, but we would like to use another technology also to enhance our organization, so we are looking for another technology for this, especially a cloud solution.""The compatibility and integration of Nutanix Acropolis AOS could be improved. For example, we have a WAF application firewall and it does not work on this solution. Not all the OS's run on AOS. You need to have a newer version of an operating system if you want Nutanix to perfectly run all the different options."

More Nutanix Cloud Infrastructure (NCI) Cons →

"OpenStack is difficult for the novice in terms of beginning to use cloud tools.""So for the main stability, there have been a couple of issues that I've experienced.""VMware has a side-to-side replication feature, which is still more mature than Rackspace OpenStack's which can't be used in a production environment."

Pricing and Cost Advice
  • "For two nodes, it cost us $10,000, and we spend $2,000 a year on support."
  • "If you are looking at a traditional SAN for a small cluster, give StarWind vSAN because you will save thousands without any compromise."
  • More StarWind Virtual SAN Pricing and Cost Advice →

  • "There is a license required for this solution and my clients usually purchase a two-year license with extended support. The price of the solution could be reduced, it is more expensive than competitors."
  • "The price of the solution is high."
  • "The pricing is quite good in comparison with HPE SimpliVity, Nutanix Scale, and even traditional architecture."
  • "When compared to the competitors, the price is reasonable."
  • "The cost of Nutanix Acropolis AOS is reasonable."
  • "We got the renewal done recently, and there was no cost involved."
  • "The price of the solution could improve. Nutanix has recently changed its pricing model from perpetual to subscription. They have identified there are challenges with the pricing model."
  • "This product is expensive, but they do have discounts. At one point, I saw that they were giving a 70% or 80% discount, which is a good thing, but maybe they should have a more realistic price and then a 5% to 10% discount."
