Introduction to the application of OceanStor ReplicationDirector in the disaster recovery data center solution (geo-redundant mode)
If the production center fails, the disaster recovery data center solution (geo-redundant mode) uses the remote disaster recovery center to recover services, ensuring business continuity. 1. One piece of OceanStor ReplicationDirector is deployed at both the local disaster recovery center and remote disaster recovery center in order to centrally manage the local production center, local disaster recovery center, and remote disaster recovery center. 2. Replication relationships are established between the storage systems used by host services to achieve both local disaster recovery and remote disaster recovery. Currently, the solution employs parallel replication (synchronous+asynchronous) and cascaded replication (synchronous+asynchronous). This solution can use storage snapshots of protected objects to roll back data, preventing data loss and virus attacks. 3. If the local production site fails, OceanStor ReplicationDirector allows the local disaster recovery site to take over its services. If both the local production site and the local disaster recovery site fail, the data backed up to the remote disaster recovery site can be used to quickly recover services. 4. The solution supports the following disaster recovery technologies: cascaded connection in synchronous + asynchronous mode for replication, parallel connection in synchronous + asynchronous mode for replication, cascaded connection in asynchronous + asynchronous mode for replication, parallel connection in asynchronous + asynchronous mode for replication, and active-active (VIS) + asynchronous replication (array).

Deployment of OceanStor ReplicationDirector in the disaster recovery data center solution (geo-redundant mode)
OceanStor ReplicationDirector (current major version: V100R003C10) is deployed in the disaster recovery data center solution (geo-redundant mode) in the following manner: 1. You can deploy one piece of OceanStor ReplicationDirector in one data center to centrally manage the local production center, local disaster recovery center, and remote disaster recovery center, or you can deploy one at the local disaster recovery center and one at the remote disaster recovery center to achieve disaster recovery management. 2. When deploying one piece of OceanStor ReplicationDirector, you are advised to deploy it at the disaster recovery center that provides the fastest service recovery services. Ensure that the management server can communicate through the management network with service hosts and storage devices at all three sites.

Applications supported by OceanStor ReplicationDirector in the disaster recovery data center solution (active-passive mode)
The disaster recovery data center solution (active-passive mode) supports the following applications: Mainstream databases: Oracle (RAC), Microsoft SQL Server (MSFC), and IBM DB2 (VCS and PowerHA) Mainstream application: Microsoft Exchange Server File system: NTFS and NAS

Application types supported by OceanStor ReplicationDirector in the disaster recovery data center solution (active-active mode)
The disaster recovery data center solution (active-active mode) supports the following applications:

Introduction to the application of OceanStor ReplicationDirector in the disaster recovery data center solution (active-passive mode)
The disaster recovery data center solution (active-passive mode) applies to local and remote disaster recovery scenarios. The production center and disaster recovery center work in active-passive mode, meaning that if a disaster occurs at the production center, the disaster recovery center quickly takes over its services. 1. To ensure disaster recovery data consistency, the OceanStor ReplicationDirector Server is installed on the disaster recovery management server (or VM) in the disaster recovery center, and OceanStor ReplicationDirector Agent is installed on each host that requires disaster recovery. 2. To achieve remote disaster recovery, remote replication relationships are established between storage systems. In addition, this solution can use storage snapshots of protected objects to roll back data, preventing data loss and virus attacks. 3. The solution supports the following disaster recovery technologies: synchronous remote replication (array), asynchronous remote replication (array), asynchronous remote replication (VIS), mirroring (VIS)+asynchronous remote replication (array), and host-based replication.
