Introduction to sites of the OceanStor ReplicationDirector

1

Resources in a disaster recovery management system are organized by site. You can configure disaster recovery services at a site or between sites. Create a local or remote site based on the disaster recovery network mode (local or remote).
Sites are categorized as local sites and remote sites by location.
- Local site: a site managed by the local OceanStor ReplicationDirector server.
- Remote site: a site managed by the remote OceanStor ReplicationDirector server.
Sites are categorized as production sites and disaster recovery sites by protection relationship.
- Production site: a site where a production system resides. Service systems of enterprises run at the protected production site.
- Disaster recovery site: a site where a disaster recovery system resides. The disaster recovery site provides backup and disaster recovery for the production site. If a disaster occurs, the disaster recovery site can be used to recover services.

Introduction to OceanStor ReplicationDirector reprotection
If planned migration or fault recovery has been performed for a recovery plan, you can implement reprotection for the recovery plan. Reprotection protects data at the disaster recovery site once devices at the production site recover from disasters, simplifying failback. This operation can be performed only in the disaster recovery management system at the disaster recovery site.

Introduction to fault recovery of OceanStor ReplicationDirector
If data or applications at a production site become unavailable due to disasters or faults, you need to recover data from a disaster recovery site. Fault recovery is performed only in the disaster recovery management system at the disaster recovery site. The latest backup data at the disaster recovery site is used to recover data.

Introduction to protected groups of the OceanStor ReplicationDirector
Protected groups are service objects that are protected by the disaster recovery management system. Protected groups consist of protected objects and protection policies. You can create protected groups for various protected objects such as databases, local host file systems, LUNs, NAS file systems, and VMs. Select different protection policies to implement disaster recovery based on RPO/RTO requirements.

Introduction to planned migration of OceanStor ReplicationDirector
If data or applications at a production site need to be recovered from a disaster recovery site due to a power failure, upgrade, or maintenance, you need to perform planned migration at the disaster recovery site. The latest data changes at the production site will be synchronized to the disaster recovery site. Planned migration is performed only in the disaster recovery management system at the disaster recovery site.

Introduction to resource discovery of OceanStor ReplicationDirector
In order to provide disaster recovery for protected objects, OceanStor ReplicationDirector needs to discover the hosts where protected objects (such as databases) reside, storage devices associated with the protected objects, vCenter servers associated with the VMware virtualization environment, cloud platforms associated with Huawei virtualization environment, and VRG.
