Huawei Updated H13-624_V5.5 Exam Questions and Answers by kobi

Small storage space occupation: A clone generated by the storage system is not a full physical data copy, which does not occupy large storage space.

Quick generation: The storage system can generate a clone within several seconds to obtain the consistent copy of the source volume data.

Lossless performance: Based on the ROW mechanism, the done write performance is equivalent to the source volume write performance.

Cascading: Clones can be created based on clone volumes or snapshots of clone volumes in the storage system. A maximum of 64 cascading levels are supported.

This technology requires CPU to process each MAC frame, which will consume a large number of CPU resources.

This technology allows to directly operate the hardware queue in the user mode, avoiding the context switching overhead.

This technology uses the polling mode, reducing the latency.

High latency overhead still exists using the technology, such as kernel mode interrupts, locks, system calls, and thread switching.

In the information collection phase, the engineer needs to collect basic information about applications and data, such as the impact of application configurations on data, data size, and read/write ratio.

In the test and application phase, the engineer needs to test the configurations to check whether the optimization objective is achieved. If yes, the engineer can put the system into use.

In the optimization analysis phase, the engineer needs to specify the performance optimization objective, find out the performance bottleneck, and identify the parts that play a key role in Improving the system performance.

In the optimization operation phase, the engineer needs to deploy DR for the service system, and needs to modify multiple configuration at a time during the optimization configuration.
