Overview of Huawei's AI Development Strategy and Full-Stack, All-Scenario AI PortfolioAssume that a government customer has purchased two Huawei all-flash storage devices for service deployment. While using the storage devices, an engineer discovers that storage performance fluctuates frequently. To troubleshoot the storage-performance fluctuation issue, the engineer must perform many operations.
- Check whether there is an obvious change in the I/O model or service load when performance fluctuates.
- Use FTDS, the storage-side latency-location tool, to analyze the modules with fluctuating latency.
- Check whether the hit rate changes abruptly when performance fluctuates.
- Check whether extremely small I/Os are present when performance fluctuates.
- Check whether there are obvious hardware-resource bottlenecks on the storage side when performance fluctuates.
- Check whether there are obvious storage background tasks when performance fluctuates.
Among these operations, which can be used for troubleshooting and which cannot?
- A Operations 1, 2, and 3 can be used for troubleshooting, while operations 4, 5, and 6 cannot.
- B Operations 1 and 2 can be used for troubleshooting, while operations 3, 4, 5, and 6 cannot.
- C Operations 4, 5, and 6 can be used for troubleshooting, while operations 1, 2, and 3 cannot.
- D Operations 1, 2, 3, 4, 5, and 6 can all be used for troubleshooting.
