Statement: Huawei OceanStor all-flash storage systems use the SmartMatrix architecture, which allows all disks to share all front-end and back-end interface modules. Failure of any disk does not affect services. Is this statement True or False?

• A. Not Applicable
• B. True
• C. False
• D. Cannot Be Determined

Answer: (C)

Redundancy in Huawei OceanStor SmartMatrix helps tolerate a single disk failure, but it does not guarantee that no services are affected. When a disk fails, the system must rebuild the lost data onto spare disks, which increases I/O load and can cause higher latency or temporary slowdown. If multiple disks fail or the rebuild encounters issues, performance and availability can degrade further or risk data availability. The architecture’s shared front-end and back-end modules enable flexible, resilient access, but that does not eliminate the temporary impact that disk failures can have on services. Therefore, the statement is false.
