What is our primary use case?
Our primary use case for Nutanix is removing the classic 3-tier architecture and switching to hyper-convergence.
Migrating from the 3-tier architecture to HCI helped us to free up rack space, remove the old hardware, and run systems on the new platform.
There was a four-rack, and now there are ten units of hardware. It's really cool and fantastic.
It is now managed from one interface, covered by technical support and it's homogenous. If you need to expand a cluster or storage then all you need is just add new nodes. You don't need to buy new storage, you don't need to expand your SAN, and so on.
How has it helped my organization?
Now, all of the systems run on the same hardware with the same software, which can be managed from a single pane of glass. All you need to know is AOS. You don't need to learn about storage, SAN, or virtualization. It's easier to start with Nutanix than start with classic architecture.
The software features which really can improve the organization are deduplication and compression. These really can help to save a lot of space. On the non-homogenous systems, we achieved approximately 2:1 space savings, which is great.
What is most valuable?
We really love the Lifecycle manager and one-click upgrades. All you need to do is run the upgrade procedure and watch it go.
You don't need to update firmware, software, hypervisors, and so on by yourself. LCM can do it for you. It really can save a lot of time. LCM will install only compatible firmware and software, so you can't install (for example) unsupported firmware and break down your system.
LCM is a really cool feature and one of the best in the market. I have never seen anything like this before.
What needs improvement?
I think there is a lot that Nutanix can improve in AOS, in particular, moving tasks such as creating trunked networks and managing nodes from the CLI to Prism Element.
I would like to see more information in Prism Element about how Curator works.
There is a lot of functionality in Prism Central, but sometimes you want to see those features in Prism Element. One of them is RBAC. If we have one small cluster, and we need RBAC, we must install Prism Central. This is an inconvenience and I hope to see this feature in Prism Element in the next releases of AOS.
For how long have I used the solution?
We are using Nutanix solutions based on AOS since 2017.
What do I think about the stability of the solution?
Nutanix AOS is a very stable system. You can lose drives or nodes, depending on your replication factor, and you will not lose your data.
What do I think about the scalability of the solution?
It's very easy to scale. You just add new nodes, increase compute, and increase storage at the same time.
How are customer service and technical support?
Nutanix has one of the best technical support groups I've ever seen.
They answer fast and they solve problems fast. They don't ask you a lot of unnecessary questions; rather, they just do the work.
Which solution did I use previously and why did I switch?
Previously, we used different solutions from different vendors. We needed to put it all together, and Nutanix helped us.
How was the initial setup?
Setting up a new cluster is easy and the documentation covers this process.
What about the implementation team?
They are very highly qualified specialists.
Which other solutions did I evaluate?
We did not evaluate other options before choosing Nutanix.
What other advice do I have?
My advice is that deduplication and compression can save money, so use it.
