Ask HN: What would you recommend as a replacement for Windows Storage Replica?

So to make a very long story short, at my job we are using Storage Replica to replicate two servers that are sitting right next to each other: one server is a mirror of the other and vice versa. We are using Storage Replica to do this since these are Windows servers but I have a few really big problems with Storage Replica:

1) The documentation is very poor

2) There is no way to configure automated failover in our current server-to-server configuration (I've been at this for over forty hours. Don't ask. It's not possible)

3) We would want to have a third, client computer that is able to manage the Windows Storage Replica servers but Storage Replica is a Windows Server feature and so can only be installed on Windows servers which the client is not

Is there another availability solution which does not share these flaws with Storage Replica? I am currently researching such but I am having a hard time searching the web for a Storage Replica replacement so I am also asking here if anybody knows of one.
