The short answer is yes, but a failover cluster implies you have more than just a couple Hyper-V hosts. You need shared storage as well, e.g. SAN.<br />

We do have an SAN. But even we have only two pretty powerful hosts with plenty of resources, still not good for failover cluster?
</div>


<div>
That's fine. You only need 2 hosts + shared storage. <br />

Can I have one more quick question please, regarding Hyper-V Replica?<br />
If we use shared storage -- SAN, and the replica server actually is physically located 100 miles away. In the event of primary host failure how can the replicated VMs (becomes in replica server -- 100 miles away from the SAN) access the SAN ?? That seems to be NOT feasible, correct?
</div>


<div>
The remote replica server would not access the local SAN that your two Hyper-V hosts running a failover cluster would be accessing. I'm assuming that the remote server is actually a 3rd server, not one of the 2 servers mentioned initially. If this is a 3rd server, you can run your 2 host failover cluster and then Hyper-V replicate that virtual environment to the 3rd server in the remote site. Hyper-V replication is free, but I wouldn't actually recommend using it. I would recommend using something like VEEAM backup &amp;&nbsp;replication to do the replication. Better disk efficiency if you want to hold onto generations of your replicas.<br />

<div>
You said you wouldn't recommend using Hyper-V Replica since its disk lower efficiency, compared to commercial backup &amp;&nbsp;replication software such as Veeam. Can you elaborate a little bit more about the reason why its lower disk efficiency?<br />
Appreciated.

HA (High Availability) Failover Cluster in 2012 R2 Hyper-V is free?

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.
