What is our primary use case?
I use it for day-to-day management of all of our clusters. I log in every day to verify that there are no alerts or critical issues going on. I use it to log in to our VMs, create new VMs, and delete or decommission old VMs. I also use it for updating our clusters and running lifecycle management checks for inventory.
The clusters are being run at our headquarters within a server room. And our three other clusters at remote offices are in a makeshift server closet. They are mainly used for end-user computing because the three remote offices have a virtual Nasuni filer. End-users at those offices are going to the filer for their home drive, department drive, and our file share. It's mainly end-user servers that run on those remote office clusters. All of our SQL databases reside on our cluster in HQ.
How has it helped my organization?
Compared to our VMware environment, it is so much easier to use Nutanix through Prism Central and Prism Element. Everything is so straightforward, especially when I have to update the AOS and AHV versions of our clusters. It literally is a one-click option. You select what you want to upgrade, hit "Upgrade," and it does a pre-check, and then it goes through the process of upgrading one node at a time. It migrates VMs on the specific node being upgraded to a different node, and brings them back after the upgrade is complete. It's just a way easier and simple environment.
It has also helped in the fact that our environment doesn't have any downtime when it shouldn't. Downtime is not an issue. Servers are up.
The overall efficiency of our environments is great.
What is most valuable?
Prism Central offers a single pane of glass user experience to manage all four of our nodes. If I want to log in to one specific cluster, I always use Element, but I use Prism Central quite a bit as well, and that's mainly for the management of our remote offices.
The Prism user interface for compute, storage, and networking is also very easy. There's a simplicity to it that makes it easy to understand. When building a VM, although there's no step-by-step guide on how to set up the VM, it's all in one small window. As long as you go step by step, it's very easy.
What needs improvement?
The three clusters we have at our remote offices are just one-node clusters. If there were an easier way to upgrade items such as the BIOS, SATA drives, the BMC, et cetera, on those, that would be helpful.

For how long have I used the solution?
We have been using Prism since 2017. That's when we implemented our first Nutanix cluster. We now have 4 Nutanix clusters
What do I think about the stability of the solution?
It's very stable. We've never had issues of things failing. In the past five years we may have had a couple of drives fail here and there, but they are always replaced. They'll ship one out within four hours. There really never are any stability issues.
What do I think about the scalability of the solution?
The scalability is great. With the environment we have right now, especially for our headquarters, we still have a lot of room to add more servers with fairly significant capacities of memory and cores.
How are customer service and support?
When I do run into issues, and I'm not entirely sure how to fix them, I always involve Nutanix support through their support portal. I never have issues with their support. They are very good at what they do.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
Overall, Prism Element is extremely easy to use and understand. Before we had Nutanix, we were using a VMware environment, and upgrading our nodes within VMware was rather difficult. It was just not as straightforward as when we upgrade our nodes and clusters within Nutanix. It literally is a one-click process to upgrade all nodes.
We were impressed with Nutanix, overall. Some of the other main drivers for our switch to it were the simplicity of setting up our Nutanix clusters, ease of management, and that their support is very respected. There is an overall ease of use, compared to VMware. I'm sold on their product.
How was the initial setup?
The onboarding of Nutanix and Prism Element and Central was very easy and straightforward. For the original cluster that we built at our headquarters, someone from Nutanix came in and helped set it up. And for two of the three nodes that we set up at remote offices, we had a consulting company come in to help set them up. I set up the last node myself using Foundation.
It was mainly me involved in the setup, along with our network engineer, to ensure that everything was set up and configured on the ports. It may have taken us a couple of hours. It was very fast and straightforward.
Maintenance on our side is required when we have to upgrade the AOS, the version of the AHV, the BIOS and the BMC. But, for the most part, at least on our six-node cluster, it's a matter of selecting the option and hitting "Upgrade." It really does it all by itself. I'm usually there just to monitor it.
What's my experience with pricing, setup cost, and licensing?
The licensing is fairly high in price. If someone can get over the fact that the licensing is fairly expensive, I would say Nutanix is the way to go. It is expensive, but to me, it's worth it.
Which other solutions did I evaluate?
At the time we evaluated solutions, we were not a very large company, so we looked at Scale Computing and we may have looked at HPE's option. Neither one of them could handle the option of adding GPU cards to our nodes, and Nutanix could. That was a driver for our choice of Nutanix, but the main reason was the overall ease of use of the product.
What other advice do I have?
Prism Central will show when there are inefficiencies between VMs. We don't own the license to allow Prism Central to show those inefficiencies. But overall, we really have never had any issues where our VMs were underutilized or had production inefficiencies with them. Our environments have been working regardless, even though we don't have the proper Prism Central license to give us that detail.
We are also backing up our virtual Nutanix environment on a daily basis. So I'm not too concerned about data protection, as a whole, because if we do have issues, there is an easy way to get things restored. But I will say that, when it comes to updating a server, I always take a snapshot of it beforehand, so if I do run into issues, I can just restore it from that snapshot.
Going into 2023, one of our main goals is security, as a whole. I'm sure there will be things across our infrastructure that we will look at on the security side. We don't use any extra Nutanix security mechanisms right now, but that possibility is in place for next year.
Overall, I'm very impressed with Nutanix. I would highly recommend to anyone who is looking for a hyper-converged infrastructure to look at Nutanix. That's mainly because of the simplicity and overall ease of use of the product, and their support.
