Hello, Lisa! Have a nice day! The two-site and three-center DR scheme is typically used in the networking with an intra-city DR center and a remote DR center, thereby providing multi-level protection for data and services in the production center. If a disaster occurs in the production center, services can be quickly switched to the intra-city DR center. When a disaster occurs in both the production center and the intra-city DR center, services can be quickly started in the remote DR center to ensure service continuity. Therefore, the two-site and three-center DR scheme ensures service continuity by quickly restoring service data in the remote DR center in the event of natural disasters or man-made accidents that may happen in the production center. The following figures show the networking of the two-site and three-center DR scheme. Figure 1 Two-site and three-center DR scheme supporting active-active DR and asynchronous replication (of storage arrays) in non-ring typology
Figure 2 Two-site and three-center DR scheme supporting active-active DR and asynchronous replication (of storage arrays) in ring typology
If you want to know more information about DR solution, you can refer to the following document: FusionSphere Virtualization Suite Product Documentation https://support.huawei.com/hedex/hdx.do?docid=EDOC1100132628&id=EN-US_TOPIC_0218496689&lang=en Hope can help you! |
