1. Dorado V6 LUNs have controller ownership.

2. To configure HyperMetro for LUNs that are carrying host services, you must first stop the host services.

3. HyperCDP objects can be used to restore data but cannot be directly mapped to hosts for read and write operations.

4. The full-stripe write technology supported by Dorado can effectively improve SSDs' service life.

5. When performing a controller fault test on the Dorado V6 mission-critical product models, ensure that each controller has a link to the host.

6. Controllers must be restarted during software NDU upgrade of Dorado V6.

7. Huawei is the only storage vendor that has passed the 9-intensity earthquake resistance certification in China.

8. Huawei HyperMetro (active-active) solution supports non-disruptive capacity expansion.

9. OceanStor 100D uses NVDIMMs as cache, which can prevent data loss during power failure.

10. OceanStor 100D provides inline deduplication.

11. OceanStor 100D can be deployed on standard universal servers.

12. Two quorum devices are deployed at the third-place site.
Both quorum devices can be used for arbitration at the same time.

13. Does incremental EC directly aggregate large objects and affect performance?

14. RAID2.0+ is a block-based virtualization technology. Disks are divided into CKs and CKGs form RAID groups. Therefore, compared with traditional RAID, RAID2.0+ does not require hot spare disks or hot spare space.

15. Huawei active-active (HyperMetro) solution must use Huawei UltraPath.

16. The system availability is 99.999%, indicating that the annual interruption time of the storage array is about 5 minutes.

17. Unity XT supports full configuration of NVMe SSDS.

18. Fusion Storage supports the iSCSI protocol only in VMware scenarios.

19. The active-active status will be interrupted if a quorum server is faulty.

20. Huawei is the only storage supplier that has passed the 9 intensity earthquake resistance certification in China.
