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.
Storage provisioning
Of the storage provisioning methods on the virtualisation platform, only thick provisioning is supported. For thin provisioning, the disk space reclamation feature is incompatible with block replication operations.

In a THIN provisioning environment, disk space reclamation causes data inconsistency issues under certain circumstances, and care should be taken to avoid installing or operating in thin environments. |
