Huawei H13-624_V5.5 Exam With Confidence Using Practice Dumps

Storage performance metrics are covered in the *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)*: “For large I/O sizes (≥64 KB), throughput is the primary performance indicator, as it measures the data transfer rate, critical for applications like video streaming or large file transfers.” Throughput, measured in MB/s or GB/s, reflects the system’s ability to handle large data volumes, making it the key concern for such scenarios.

The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* details the low-level design (LLD) mode for Huawei scale-out storage: “In LLD mode, the Storage Deployment Tool (SDT) is used to plan nodes, networks, and clusters, generating a configuration file that guides subsequent installation and deployment.” The SDT ensures precise configuration for complex deployments, making it the correct tool for this task.

The OceanStor Pacific parallel file system service is designed for high-performance file access. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* explains: “The parallel file system aggregates small I/Os in cache to optimize latency and small file utilization. Large I/Os are forwarded to the home node, bypassing scale-out locks to reduce latency. Large I/Os use passthrough mode for direct disk writes, enhancing bandwidth. The system uses dynamic indexing, not fixed-length large-granularity indexes, to adapt to varying I/O patterns.” Let’s evaluate:

- Option A: True. The material confirms small I/O aggregation in cache for better latency.

- Option B: False. The system uses dynamic, not fixed-length, indexing, making this statement incorrect.

- Option C: True. Direct forwarding to the home node reduces lock overhead and latency.

- Option D: True. Passthrough mode for large I/Os improves bandwidth, as per the material.

Thus, option B is false.
