To provide PB-level data backup

Outstanding performance

Superb reliability

Large scale

If links between sites are down or the non-preferred site fails, LUNs at the preferred site continue to provide services and those at the non-preferred site stop providing services.

If the storage system at the preferred site is faulty, the non-preferred site automatically takes over active-active services.

If a user powers off the storage system at the preferred site for maintenance purposes, the storage system at the non-preferred site immediately takes over all active-active services without service interruption.

The static priority mode provides higher reliability than the quorum server mode.

Data in the snapshot volume is the same as that in the source volume at 9:00 am.

Data in the snapshot volume is the same as that in the source volume at 09:10 am.

Data in the snapshot volume is the incremental data generated during 9:00 am to 9:10 am in the source volume.

The snapshot volume is a physical copy of the source volume generated at 9:00 am.

Only OceanStor storage devices can be deployed at the primary and secondary sites.

At the primary site, only OceanStor storage devices can be deployed. At the secondary site, the third-party storage devices can be deployed.

At the primary site, the third-party storage devices can be deployed. At the secondary site, only OceanStor storage devices can be deployed.

The third-party storage devices can be deployed at both the primary and secondary sites.

No. An Active-Active DR Solution requires that two OceanStor 2600 V3 or higher-level storage devices be separately deployed in the two data centers.

No. An Active-Active DR Solution requires at least one set of OceanStor 5600 V3 or higher-level storage.

No. An Active-Active DR Solution requires at least one set of OceanStor 5800 V3 or higher-level storage.

Yes. All conditions required for the solution are met.

If the storage system is faulty, there may be 30 minutes of data differences between the production site and the disaster recovery site.

If the storage system is faulty, there may be 45 minutes of data differences between the production site and the disaster recovery site.

It takes about 15 minutes to bring one or more applications back from an outage to a correct operational state.

Compared with disaster recovery, backup provides a finer restoration granularity, such as taking files as the restoration level and offering multiple backup points in time.

If source data and its backup data have the same format, a host can directly read and write the backup data.

Backup software can back up data to tapes for offline archiving.

Disable write protection at the secondary site.

Change the restoration policy to manual.

Split pairs.

No operation is required.

The primary storage system returns a write success response to the host immediately after data is successfully written to the primary LUN.

After an asynchronous remote replication relationship is established, an initial synchronization is implemented.

When a secondary LUN is added to an asynchronous remote replication, snapshots of the primary and secondary LUNs are automatically created and activated.
