In disaster recovery applications, the HyperMirror function (remote data replication) can only be accessed between two OceanStor 5300 V3 Yes, it cannot be performed between OceanStor 5500 V3 and OceanStor 5300 V3.

• A.FALSE
• B.TRUE

Description 1: The LUN is composed of multiple Extents in the storage pool.

• A.Description 1 is wrong, description 2 is correct
• B.Description 1 is correct, description 2 is incorrect
• C.Description 1 is correct, description 2 is correct
• D.Description 1 error, description 2 error

With the advent of the era of big data, the corresponding storage technology is also undergoing changes.
Is the following statement correct? (Multiple choice)

• A.The file system develops from a local file system to a cluster file system and a distributed file system
• B.Traditional NAS, facing PB-level data, complex volume management and unbalanced system capacity allocation, will result in waste of resources
• C.Having large-scale expansion capability is the characteristic of mass storage system
• D.The mass storage system is characterized by a more complicated file system and more complicated management

Regarding the steps of SAN synchronous replication, what is the correct order?
(1) The production storage receives the host write request. HyperReplication logs the request. Only the place is recorded in the log Address information, without recording data content.
(2) HyperReplication waits for both the primary LUN and secondary LUN write processing results to be returned. If both are written successfully, clear Log; otherwise keep the log, enter the abnormal disconnection state, and then copy the corresponding number of the log address again when starting synchronization According to the block.
(3) Write the request to the master LUN and slave LUN. Normally, the LUN is in the write-back state, and the data will be written Cache.
(4) Return the processing result of the host write request, which is subject to the processing result of the write master LUN.

• A.(1) (3) (2) (4)
• B.(1) (2) (3) (4)
• C.(2) (1) (3) (4)
• D.(4) (2) (3) (1)

Which of the following statements about RAID technology are correct?
(Multiple Choice)

• A.Performance of all RAID levels increases with the number of member disks.
• B.Disks are striped for storing data blocks, shortening the mechanical seek time and accelerating data access.
• C.Several disks in an array are accessed simultaneously (parallel access), shortening the mechanical seek time and accelerating data access.
• D.Current RAID technology only uses the parity check mechanism to protect data.
