Huawei Certified ICT Professional – Storage (HCIP-Storage) — Question 8

A live gaming platform uses the FlashLink multi-core technology of Huawei OceanStor all-flash storage for its services. Which of the following describes core grouping in CPUs?

Answer options

• A. A request is processed by one core until its completion. Cores are lock-free to avoid frequent switchovers among the cores.
• B. Read/write I/Os are deployed in different core groups from other types of I/Os to avoid mutual interference.
• C. The controller works with SSDs to identify hot and cold data in the system, improve garbage collection efficiency, and prolong the service life of SSDs.
• D. vNodes are bound to CPUs to reduce the overheads for scheduling and transmission across CPUs.

Correct answer: C

Explanation

The correct answer is C because it highlights the controller's role in managing data based on usage, which is essential for optimizing performance and longevity of SSDs. Options A and B do not specifically relate to core grouping but rather to processing methods and I/O management. Option D discusses vNodes and CPU binding, which is not directly relevant to the core grouping concept.
