Huawei's all-flash storage system software adopts the Symmetric Active-Active architecture. Which of the following description is incorrect?

• A.  LUN data is evenly distributed in the caches of all nodes and processed by all controllers
• B.  RAID2.0+ technology makes the effective data evenly distributed to all the hard disks in the storage pool, and realizes the load balancing of the hard disks
• C.  When customers create LUNs, they need to plan the ownership of the LUNs from afar to achieve load balancing of the controllers.
• D.  Determine the controller that is processed by the host read and write requests by performing HASH calculation on the LBA of the read and write requests

The customer F plans to purchase Huawei data protection all-in-one machine for data protection of the production system. The customer's current business status is as follows: the peak time of the system's business is 9:00-18:00 on working days, and the customer requires the backup time to be minimized. The business data is a small file, but the total capacity is large. Based on this scenario, which one of the following statements is correct when using Huawei Data Integrated Protector to formulate a backup strategy? (Multiple Choice)

• A.  To avoid high business hours, backup can be performed at 23:00-6:00
• B.  Volume backup is not suitable for many small file farms in the morning
• C.  The enterprise backup should be performed off-peak, and the backup of large data volume should be combined with backup of small data volume
• D.  If the full backup time is too long, it is scheduled to be performed during the weekend time window, and incremental or differential backups can be performed every night

Which of the following methods can be used to determine whether an SSD device has reached a bottleneck? (Multiple Choice)

• A.  Client data is significantly slower
• B.  Check the performance of the SSD device to see if it reaches the officially released performance value
• C.  Use iostati to check the SSD device parameters, whether the svctm value is significantly increased
• D.  For SSD, check if %until reaches 100%

An archive will expand its data center storage system. In the process of capacity planning by engineers, in addition to data capacity, file system, RATD level, hot spare space, coffer disk, value-added features, etc., it is also necessary to consider capacity variances between hard drive manufacturers and operating systems.

• A.  TRUE
• B.  FALSE

Enterprises use Huawei Data Protection All-in-Ones to protect the operating system and volumes in the production environment using a continuous backup solution. Continuous backup can perform full-machine backup and recovery of operating system volumes and data volumes.

• A.  TRUE
• B.  FALSE
