Scale Computing HC3 supports 1-to-1 replication as well as many-to-1 replication. 1-to-1 replication includes support for cross-replication between two systems, meaning source-to-target and target-to-source. 1-to-many replication means that different VMs from one system can be replicated to different remote systems; with HC3 the same VM cannot be replicated to different remote systems. Many-to-1 means that multiple source systems can replicate VMs to the same target system. A maximum of 25 HC3 source systems can replicate to a single HC3 target system.
