We performed a comparison between Nutanix Cloud Infrastructure (NCI) and Rackspace OpenStack based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, VMware, Nutanix and others in HCI."Starwind support is excellent. They are very fast and have very good knowledge of Starwind and Hyper-V Cluster software."
"The price was right."
"It also provides a seamless and efficient solution for personal storage requirements, showcasing the versatility and scalability of my Virtual SAN configuration."
"StarWind Virtual SAN is essentially hardware agnostic, allowing us to build out a specific hardware layer based upon the customer's unique requirements."
"The product only requires two VMWare ESXi host servers versus three host servers for VMware's comparable solution."
"The support has been amazing and quick to reply."
"We can lose a site or even two of our three, and we would lose no data and have no outage."
"The performance of the solution is accurate and concise."
"The architecture of Nutanix is the best, and the virtualization we get, out of the box, is an advantage. Also, dedupe and compression are done natively, inside the platform, so there are no additional licenses. That adds value to it."
"It is less expensive than VMware products. It is also a little bit more flexible, but it really comes down to price for us."
"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."
"A great feature involves real-time hardware changes."
"The virtualization environment is now much easier to manage and maintain, there is only one vendor to call in case of issues and one single console to manage everything."
"The hyperconvergence service, as well as the DR solution, are game-changers for Nutanix."
"The flexibility of this system is very good. It's also faster than others, and has skilled technical support who showed more initiative than a competitor, e.g. VMware."
"It has centralized management. It is easy for an engineer to manage. More work goes to patching, upgrades, and maintenance. Nutanix is very easy to upgrade. It takes one click. Engineers do not need to spend additional time with Nutanix for upgrades. With one click, it will complete the upgrade and show the results. Other hypervisor solutions are not like this, specifically since you must do all the components one by one."
"The solution is stable."
"The most valuable feature is the customization. With the customization you can really give the customers what they want."
"Administrators are very comfortable with the functionality and services OpenStack offers."
"It created a reusable library with OpenStack features."
"The documentation was plentiful and very helpful."
"There are many services that can be directly used which are not available in VMware."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"The initial setup isn't too difficult."
"It should reclaim white spaces after big files are deleted."
"It would be nice to add the ability to use raw partitions instead of file containers."
"Perhaps more reporting features on the utilization, usage, and performance of the configured high-availability images and underlying physical disks would be helpful."
"For improvement, I would like to see how the software determines which networks to use for which purpose. It seems like the naming terminology changes a bit from here to there."
"The system performs as expected, but we're always looking for performance improvements regarding the best utilization of NVMe disks."
"Initially, when we first started, the sync was horrible."
"Besides not being able to use any filesystem, I do not have any additional cons."
"I had issues locating the documentation that applied to my version of StarWind vSAN."
"The GUI for this solution needs improvement."
"It already has the capability to integrate with the major cloud providers but, in an upcoming release, if there is a possibility to have it integrate with other cloud providers like IBM, Alibaba, and other moderate-level cloud providers, that would be good."
"Make it easier to manage."
"When we have issues with the solution, they tend to be around networking."
"Nutanix can be a bit complex to understand."
"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."
"The software-defined networking should be improved. It is quite substandard as compared to the VMware variant. The software-defined networking is quite limited, and we usually use other products to do that. We're aware that Nutanix is working on that and will be coming out with better solutions, and we can't wait because to do a fully software-defined architecture, the abstraction layer needs not only software-defined storage, which you have, but also the software-defined networking piece."
"Nutanix needs to improve network features like Passthrough – SR-IOV. It could be improved by supporting SR-IOV, if they had that support, I would not have needed to implement the VMWare vSAN."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"The line migration is a problem."
"It should have a single dashboard for cloud management and on-premises systems"
"It could use more examples in different languages (API use cases)."
"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."
"So for the main stability, there have been a couple of issues that I've experienced."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
