My storage device is OceanStor V300R006,There is a storage array here, and multiple virtual machines are configured. One of the virtual machines is configured with Oracle database services,
I need to do a virtual machine migration service in addition to the Oracle database virtual machine,It is found that the performance of Oracle business has dropped significantly.
Can you make some suggestions?

Hello, sir!

I feel that the virtual machine migration service will consume a lot of bandwidth resources.

The performance of the Oracle database services is affected. Run the change full_copy job_information command in the developer mode to set the copy concurrency and speed of VAAI. 

In the command, speed indicates the copy speed and concurrent_value indicates the number of concurrent copy tasks. By setting speed=low, concurrent_value=2.
