To use this Windows Server Failover Cluster (Cluster A) to store VM hard disk files for another cluster (Cluster B), you'll need to add the File Server role to Cluster A and then add the Hyper-V Replica Broker role to it after installing the Hyper-V role on its nodes. Configure the File Server role on Cluster A to provide a shared network location (SMB share), then in Cluster B's Hyper-V Manager, enable replication to Cluster A's Hyper-V Replica Broker, using the shared location for the initial replication.
