What is our primary use case?
We originally had a three-node Nutanix cluster. However, we were asked to spend six figures on replacing it, as the Nutanix license was bound to the hardware. StarWind Virtual SAN could use this existing hardware without any special reconfiguration.
We decided to go with their Linux appliance and quickly learned we could achieve the same resiliency with two nodes as we did with three nodes on Nutanix.
They provided guides to help us set up the most efficient cluster, although we did have to use MD/RAID as there wasn't a guide available for ZFS.
How has it helped my organization?
Besides being 80% cheaper than the other alternatives, the simplicity makes reconfiguration and support much easier. The performance is much higher than we anticipated and outperforms the other solutions we've tried.
They provide numerous guides and whitepapers to help set up your own environment, yet can also walk you through the setup, so you understand each component of it. Thanks to their extensive support community, we are no longer 100% dependent on support (or a support contract) for minor troubleshooting issues.
What is most valuable?
The most valuable feature to us is the basic setup, which makes it easy to understand what's happening under the hood. This, combined with the low price point, allowed us to rapidly implement the solution while giving us better performance than all other products we tested.
All of the documentation is openly available and isn't hidden behind a support paywall like many other options. Since the setup was so simple, I opted to do the majority of setup myself, however, support was always available to answer any questions or to provide guidance.
What needs improvement?
A web management interface would be good, especially for those coming from other solutions that have one. All of the setup and configuration is done via a dedicated Windows application, so you'll have to install it on every machine that you want to manage the cluster with.
Most of the documentation is heavily windows-based, so finding guides on their Linux VSA can be difficult, however, support can usually assist you in finding the documentation.
An easy/native ZFS option would also be welcome, as we did end up having to use a mdadm setup, but none of these are deal-breakers.
For how long have I used the solution?
I've used the solution for three months.
What do I think about the stability of the solution?
It's stable enough that I sometimes forget it's there. There are so few components in it that there's just less to go wrong.
What do I think about the scalability of the solution?
We were able to have the same resiliency with two nodes as we did with three nodes under Nutanix. It also managed to outperform Nutanix by a fair amount.
How are customer service and support?
Support has been phenomenal. They have always responded to emails in mere minutes, and everyone seems to know their stuff. I've never been transferred around, and they've always answered my question or resolved the issue in minutes.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
We previously used Nutanix, which was extremely expensive and nearly ALL of the documentation was behind a support contract. Most of the components had cryptic names, and there were very few options for finding a solution yourself.
How was the initial setup?
The initial setup is extremely simple, and support can walk you through it or give you guides if you are a do-it-yourself kind of person.
What about the implementation team?
Most of the implementation was done in-house, but support was available at any time to answer questions or to provide suggestions. Everyone we worked with on support seemed to know what they were doing.
What was our ROI?
It came in 80% cheaper than all of the other solutions, and the yearly support contract was a third of the price as well.
What's my experience with pricing, setup cost, and licensing?
If cost and performance are your goals, then definitely look at StarWind. It's a smaller company than almost all of the alternatives, yet they have very dedicated support staff and a great development team. It doesn't have all the bells and whistles as some others. However, if you're looking for a simple hyper-converged solution, this is your best bet.
Which other solutions did I evaluate?
We evaluated multiple options, including a software-only Nutanix solution and the VMware vSAN. These were both very expensive and had a very strict hardware compatibility list, which caused the project's budget to swell exponentially. We also looked at some open-source options such as ESOS and GlusterFS, however, these required many hours of setup and there wasn't a real enterprise support option for either.
What other advice do I have?
They have a great trial system with full support, they even extended mine due to my limited time to deploy and test everything.
Which deployment model are you using for this solution?
On-premises
