Hello!
The question arose of how, without a separate disk shelf, on the basis of two servers, to make a fault-tolerant storage in order to store virtualok files there. Those. each server has an up-to-date copy of the VM.
How can this be implemented on the basis of Microsoft technologies?
Thanks in advance

You can't build a failover cluster for Hyper-V without external storage. As already mentioned above, on the basis of two servers, it is only possible to implement the Active-Passive scheme when you have VMs replicated from one server using Hyper-V Replica to a neighboring one. Failover is made by hand.

Perhaps it is worth looking towards Hyper-V 2012 and replication. The solution is working, only in case of failure the second one must be raised by hand.

dfs is not.
You need to dig somewhere in the direction of snapshot replication, when every couple of minutes a snapshot of your virtual machines is copied to another host.
in the event of a fall with a slight movement, the virtual machine should start, the maximum that will be lost is everything for the update period
