company's corporative rules prohibit us to implement something new without successfully passing all the tests in the test lab. Right now we have two nodes with Hyper-V Server 2016 on top. The only useful link I found regarding this situation https://www.starwindsoftware.com/blog/free-smb3-failover-file-server-on-microsoft-hyper-v-server-2016 So I wonder, is there any other possibility to create something similar to file share with Microsoft free version and what do you think about such implementation, should I try to use it?
Definitely, you can deploy File Server on a free Windows Server version. Moreover, you can create high available Failover File Server over your Hyper-V Server. The only concern here is license question. If you make it, you will violate the Microsoft license agreement so make at your own risk.
