What The World Says About Us

StarWind gets praise for its solution's high level of customization in the 2019 Magic Quadrant for HCI


We were able to build 2-node storage clusters based on virtualization in 19 hypermarkets without any problems and with high cost-efficiency.

Vass Sandor, IT Infrastructure Leader

By being able to virtualize our environment with StarWind, we were able to retire some old hardware, get our services highly available, reduce power consumption and heat in our server closet.

David Gardner, Information Systems Manager

We are satisfied with StarWind. The support is really fantastic. Whenever any issue arises, the response is very prompt, and solution is immediate.

Srinivas Kouda, Company’s Representative

StarWind got us off the clustered environment, which was a big help. So, I could regain control of my storage and reclaim and redistribute the space we desperately needed.

Ryan Fulton, Company’s Representative

Price + Simplicity. StarWind VSAN offers great pricing and allows us to get work done without expensive custom hardware. It also makes getting back online quick and easy after an outage or hardware failure.

Aaron Hayes, IT Manager

We chose StarWind Mainly because of the cost compared to other vendors. Simplicity of setup was also a major factor and I like the fact that you don’t need a vendor certified engineer to perform the installation.

John Harris, Windows System Administrator,
Department of Physics, University of Oxford

Because of recommendations of older colleagues, with StarWind, we got a reliable storage with no additional hardware. There was a need to increase IT infrastructure performance and we saw StarWind as the most cost-effective solution.

Željko Medić, Director of IT Department

StarWind is the best storage product I have ever used! It satisfies and exceeds requirements.
