A single source system replicates different storage resources to multiple target systems. A
Source Volume (S1) in Site A is replicating to a Target Volume (T1) in Site B. At the same
time, a Source Volume (S2) in Site A is replicating to a Target Volume (T2) in Site C. So does
S3 in Site A to T3 in Site D.

Multiple source systems replicate to a single target system. A Source Volume (S1) in Site B
is replicating to a Target Volume (T1) in Site A. At the same time, a Source Volume (S2) in
Site C is replicating to a Target Volume (T2) in Site A. So does S3 in Site D to T3 in Site A.

Combination with bi-Directional, one-to-many, and many-to-one, remote replication also
supports Many-to-Many topology. Multiple source systems replicate to multiple target
