Depending on the capacity of the replication volume, you need to estimate the capacity of the metadisk. It requires about 33MB of meta disk space per 1TB of the replication volume, and for more accurate size, see Metadata Size Estimation.
Network
throughput
In a recent corporate environment, mirroring on a local network is generally configured with a bandwidth of 1 Gbps to 10 Gbps, and a remote replication environment (Disaster Recovery) for DR (Disaster Recovery) is generally operated with a lower bandwidth. That is, it is applied to a wide range of network environments from very low bandwidth (10 ~ 100Mbps) to high bandwidth. However, because replication in a low-band network environment is bound to affect replication performance due to bandwidth limitations, consider such as linking replication accelerators for performance improvement.
ports
The mirroring ports for replication (specified in the configuration file) must be open. On Windows, additionally TCP loopback ports 5678, 5679 must be open for control.
Storage provisioning
It is only supported for the THICK provisioning method of storage provisioning. Thin provisioning environments with disk space reclamation are not compatible with BSR.
