Question 172

Regarding the members of Huawei's remote replication consistency group, which of the following statements is correct:

The remote replication consistency group and its members must have the same attributes

The master and slave luns of the members of the remote replication consistency group can be in any controller.

All members are synchronized together, split, and master-slave switching

If there is a member replication link failure in the consistency group, the data replication of other members will also be

Question 173

Parallel deduplication is highly reliable. The built-in failover capability enables uninterrupted backup operations, Even if one node is unavailable in the grid, the remaining nodes can continue to work and take over the backup. The failed node is automatically repaired in the background, and then add Enter the network to continue working.

Question 174

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:

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

Question 175

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
