According to fault classification, faults that have no impact on storage system performance or host services belong to ( ) faults.

Among storage device performance indicators, latency refers to the time interval from initiating an IO request to the completion of IO processing.

A bank purchased a new all-flash storage device (such as Huawei OceanStor all-flash memory), and the engineer initialized and configured the device. Which of the following operations is correct?

The active architecture of Huawei's mass storage system ensures load balancing of high-concurrency transaction services. With this architecture, I/OS is evenly distributed to all frontends for access to load balancing.

Businesses need to back up SQL server databases and operating system applications. Service data is mainly generated from 9:00 to 18:00. The backup system must be highly stable and reliable. In this case, storage engineers can perform backup operations during off-peak hours, for example, from 23:00 to 06:00.
