D. Deduplication on the target side
SCSI communication is initiated by the initiator and received and processed by the target. When the host and the storage device communicate, the storage device
The side assumes the role of initiator.

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

The working controller of the managed LUN will be switched to a working controller.
Description 2: The working controller and home controller of a LUN must be unified into one controller.
