During the data migration process of SmartMigration, the data request issued by the host I/O is communicated.Synchronize to the source LUN and target LUN in real time by double-write to ensure that the data after the migration is completely consistent. The following statements about double-write are correct.It is true:

Double write can make the I/O request of the source LUN be issued to the local Cache and the peer Cache at the same time.This ensures the data consistency between the local Cache and the peer Cache.

Only the source and target ends can write successfully to eliminate DLC, otherwise keep DCL

During the dual writing process, the source and target luns have their own DLC record data differences.

Double write can make the I/O request of the source LUN be issued to the local Cache and the peer Cache at the same time.This ensures the data consistency between the local Cache and the peer Cache.

Only the source and target ends can write successfully to eliminate DLC, otherwise keep DCL

The following is the correct statement about Huawei hybrid flash storage SmartQos I/O priority scheduling:

The I/O priority is based on the priority of the LUN where the IO is located. The priority of the LUN is determined by the user according to The business importance of deployment on the LUN is determined

When the hard disk occupancy rate is too high, in order to ensure the reliability of the hard disk, the system will add time to the low priority I/O Delay to control, and try not to affect high-priority I/O

I/O priority scheduling resources include front-end host concurrent resources, back-end hard disk concurrent resources, CPU computing resources and cache resources
