Storage Replica is a new feature in Windows Server 2016 and provides block replication from a storage level for a data recovery plan or for a stretched cluster. Storage Replica can be used in the following scenarios:
Server-to-server storage replication using Storage Replica
Storage replication in a stretch cluster using Storage Replica
Cluster-to-cluster storage replication using Storage Replica
Server-to-itself to replicate between volumes using Storage Replica
Regarding the scenario or the bandwidth and the latency of the inter-site link, you can choose between a synchronous and an asynchronous replication. For further information about Storage Replica, you can about read this topic at: https://technet.microsoft.com/en-us/windows-server-docs/storage/storage-replica/storage-replica-overview.
The SMB3 protocol is used to make Storage Replica. You can leverage TCP/IP or RDMA on the network. I recommend you implement RDMA when possible to reduce latency and CPU workload and to increase...
