Thanks to StarWind VSAN, we were able to move to a cluster from stand-alone hypervisors with DAS (Direct attached storage). Before VSAN, hypervisor configuration changes and updates resulted in VM outages. Now, downtime is dramatically reduced.
The ability to use existing hardware, with no need to purchase hardware appliances is the most valuable feature.
The cluster configuration is time-consuming and tedious. StarWind's guide for a two-node cluster can be found at (https://www.starwindsoftware.com/resource-library/starwind-virtual-san-hyperconverged-2-node-scenario-with-hyper-v-server-2016) and it is a long document to work through. I am not sure if it is possible to make the confiugration process more streamlined on generic hardware. This only affects the cluster configuration, not it's production use. I am very satisfied with the StarWind features so far and not interested in additional ones.
The technical support is very good.
StarWind is our first hyper-converged solution.
The licensing is straightforward, with free and trial versions available.
Use the trial version before buying. Contact StarWind support in case of questions or issues. The support is very good.
Before choosing this solution we evaluated HPE SimpliVity, Scale Computing, and Dell EMC.
In my opinion, StarWind is a great solution for businesses with limited infrastructure budgets.
