The HyperCDP (Continuous Data Protection) feature in Huawei all-flash storage, like OceanStor Dorado, provides high-frequency snapshots. The *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)* states:
- Option A: True. “HyperCDP snapshots can be used for data analysis, application testing, and backup, as they provide consistent point-in-time copies.”
- Option B: True. “After a HyperCDP snapshot is created, write requests to the source LUN use copy-on-write (COW) technology, storing new data in a new storage pool location and updating the source LUN’s pointer.”
- Option C: False. The material clarifies: “HyperCDP snapshots can be directly mapped to hosts as read-only LUNs, without requiring file system sharing, for accessing point-in-time data.”
- Option D: False. “HyperCDP is optimized for high-density snapshots with low memory overhead, using metadata structures rather than full file system objects.”
Thus, options A and B are true.
