They have some awesome guides online that show you exactly how to configure the product, how to do the initial setup, and you can speak with them directly who will be able to connect, verify your setup, run its parameters, and see exactly what's working and what is not, and adjust it, and they really help you with that.
The customer support from StarWind Virtual SAN is great, as the people are knowledgeable and have great knowledge about the product and the functionality we require in the system.
Pure Storage FlashBlade is scalable.
There are between 5 and 10,000 people using it in our organization.
The scalability of Microsoft Storage Spaces Direct has been extremely good, allowing for both vertical and horizontal expansion.
It has limitations; it's configured for eight servers per site but can be scaled to 16 servers.
The scalability of Microsoft Storage Spaces Direct is limited.
If we want to expand our storage or add disks, it is easy to add them, configure the RAID, and then deploy it.
I believe that scalability should be further improved, especially considering the possibility that environments may grow exponentially.
When you move from a two-node cluster to a three-node cluster, you have to completely redo the way that they are connected to each other with iSCSI.
In case there is any issue with any blade, the data is moved to another.
Microsoft Storage Spaces Direct has been incredibly stable as long as it is configured correctly; incorrect configurations lead to surprises, which is common with any product.
Storage Spaces Direct is stable enough, however, there can be some glitches.
In my experience, StarWind Virtual SAN is very stable, and I have never had a single instability issue.
It has been working for five years and the customer is still happy with it.
I ran it on a two-node Hyper-V cluster setup, and I didn't experience any unexpected crashes or major issues.
Technical support definitely needs significant improvement.
Its configuration should be easier.
One way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade.
The licensing for Microsoft Storage Spaces Direct could be improved to be clearer, as calculating license requirements requires significant expertise; even Microsoft resources do not provide the full picture needed for licensing, leaving gaps that become evident once we move to deploy solutions.
One year ago, I had a problem, and it was difficult to identify and solve due to a lack of tools.
The performance of Microsoft Storage Spaces Direct is challenging when trying to support both NVMe and SATA SSDs, and there are problems regarding performance that need to be addressed.
A more intuitive interface or an improved dashboard for monitoring the cluster would also be helpful, as it would facilitate performance tracking and help identify potential issues before they affect services.
There have been cases where not understanding exactly what's failing on the Virtual SAN has been an issue.
Limited feedback in the management GUI is the main area where I would like to see StarWind Virtual SAN get better.
The pricing of Pure Storage FlashBlade is expensive compared to other products I used from other companies in the past, but one benefit is that they have built-in ransomware protection.
Regarding pricing, it is okay; we needed exactly this in size, and the price was a lot lower than competitors, making it good for us.
I find the Azure Local to be a bit expensive, especially due to hidden costs associated with additional tools needed for monitoring and alerting.
Pricing is an advantage of Storage Spaces Direct.
The costs are acceptable and very competitive compared to other hardware-only HCI solutions.
I talked to the sales team, they gave me a quote with a perpetual license with the support and everything went through smoothly.
This is a great product and good support even you are using free version!
