How do I configure a stretch cluster without shared storage between two sites?

I am trying to redesign our IT infrastructure and seeking help in implementing DR solution for our company.

I see that as 2 data centers in active-passive mode with the data replication. Currently we have two Windows Servers 2016 at the primary site and a single Windows server at DR location.

Between the sites we have 1Gb network connection, but I'm not sure about the latency though. So I am just wondering if it would be possible to configure some kind of storage replication to ensure the data is available to these 2 sites?

Now I am leaning towards a stretch cluster with the Storage Replica, but looks like I need to acquire an additional node for my DR site to implement that.

So could someone point me into the right direction?

This is an article where you can learn more about the main idea behind Storage Replica, all its prerequisites and features: https://technet.microsoft.com/en-us/windows-server-docs/storage/storage-replica/storage-replica-overview

And here you can find the guide on how to implement volume replication with stretched cluster: https://www.starwindsoftware.com/blog/how-to-configure-storage-replication-using-windows-server-2016-part-2

Please note that you need Datacenter licencies to get started with Storage replica.
