Huawel OceanStor Pacific series products provide object storage capabilities and support cross-site disaster recovery (DR).

In cross-site DR cluster deployment mode, each site is independent. Specifically, it has an independent DeviceManager GUI and independent erasure code (EC) configuration.

In backup and archiving scenarios that do not require a low latency, the redundancy mode between sites can be set to EC redundancy during cross site DR configuration.

During cross-site DR configuration, if replicas are used for redundancy protection across sites, each site has complete object data.

The cross-site DR of OceanStor Pacific series uses an asynchronous replication mechanism. The recovery point objective (RPO) is greater than 0, and the traffic control configuration cannot be adjusted.
