This question tests knowledge of the reliability features of the Huawei OceanStor Pacific series, as covered in the *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)*. Let’s evaluate each option:
- Option A: False. The training material states: “OceanStor Pacific uses advanced erasure coding (EC) and multi-copy technologies for data reliability, moving beyond traditional disk-level RAID modes.” While RAID-like concepts may be used internally, the system primarily relies on distributed EC or replication, not traditional RAID, making this statement inaccurate.
- Option B: True. The material confirms: “Kunpeng processors integrate multiple chip functions, reducing points of failure and enhancing hardware reliability.” This is a correct statement.
- Option C: True. The material notes: “Link aggregation ensures transmission link redundancy, with automatic switchover or isolation for faulty or subhealthy links, maintaining service continuity.” This is accurate.
- Option D: False. The material clarifies: “Multi-copy technology ensures data redundancy across nodes, but it does not implement intra-node RAID. If a node fails, reliability depends on inter-node copies or EC, and it is not necessarily higher than EC mechanisms, which are optimized for distributed systems.” This makes the statement false, as it misrepresents the technology and its comparative reliability.
Thus, options A and D are false.
