Exam H13-624_V5.5 Topic 2 Question 253 Discussion

Actual exam question for Huawei's H13-624_V5.5 exam
Question #: 253
Topic #: 2
Assume an industry customer purchased several Huawei flash storage devices for service deployment. During routine management, an engineer found that the host bus adapter (HBA) driver version of the host is outdated and the number of concurrent HBAs was insufficient. As a result, the latency on the host differs greatly from that on the storage side. Which of the following measures can the engineer take to optimize performance?

Suggested Answer: B,C Vote an answer

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* addresses host-side performance issues: "Outdated HBA drivers or insufficient concurrent HBAs can cause high host latency. Upgrading the HBA driver to the latest version ensures compatibility and performance. Adjusting the multipathing software's load balancing algorithm to min-task optimizes I/O distribution across paths, reducing latency." Let's evaluate:
- Option A: Incorrect. HBA vendor software may query settings, but modifying concurrent HBAs is typically a firmware or driver-level task, not a standard management software function.
- Option B: Correct. Upgrading the HBA driver resolves compatibility and performance issues.
- Option C: Correct. The min-task algorithm balances I/O to minimize queuing delays.
- Option D: Incorrect. Cache prefetch policies affect storage-side performance, not host-side latency caused by HBA issues.
Thus, options B and C are the correct measures.
