Disaster recovery alarm monitoring supported by the OceanStor ReplicationDirector
The OceanStor ReplicationDirector (mainstream version: V100R003C10) supports disaster recovery alarm monitoring. The OceanStor ReplicationDirector monitors alarm reporting when disaster recovery resources go offline, objects in a protected group are not in the consistency protection relationship, data synchronization for protected groups fails, and RPO does not meet requirements.

Introduction to OceanStor ReplicationDirector in the local protection disaster recovery solution
The local protection disaster recovery solution uses snapshot technology to ensure local availability of host services. This solution can use VIS snapshots of protected objects to roll back data, preventing data loss and virus attacks. The OceanStor ReplicationDirector Server is installed on the DR management host deployed in the production center and the OceanStor ReplicationDirector Agent is installed on production application hosts to ensure DR data consistency. This solution supports the snapshot (array and VIS) technology.

Policy-driven automatic disaster recovery supported by the OceanStor ReplicationDirector
The OceanStor ReplicationDirector (mainstream version: V100R003C10) supports policy-driven automatic disaster recovery by using Huawei disk array features (such as remote replication, snapshot, and three data centers in two cities) and VIS features (such as remote replication, snapshot, and mirror). Policy-driven automatic disaster recovery simplifies disaster recovery, reduces management complexity, and improves management efficiency. To implement disaster recovery, you only need to configure a disaster recovery policy based on your requirements. A disaster recovery policy defines the protection mode and scheduling policy that the disaster recovery system uses to provide protection for protected objects. A disaster recovery policy is created using the policy template when a protected group is created.

Disaster recovery host types supported by an OceanStor ReplicationDirector agent
An OceanStor ReplicationDirector agent supports the following disaster recovery host types: Windows, Linux, AIX, and HP-UX.

Visualized disaster recovery process supported by the OceanStor ReplicationDirector
The OceanStor ReplicationDirector (mainstream version: V100R003C10) supports visualized disaster recovery. It monitors progress and collects time statistics of disaster recovery tasks, such as failover, planned migration, test, clearing, and reprotection. In addition, it allows you to modify the procedure of a recovery plan.
