What is the correct description of the advantages of Huawei RAID 2.0+?

• A.  There is no write penalty in RAID2.0+, which overcomes the write penalty in RAID 5 and RAID 6 levels in traditional RAID technology The impact of the penalty on the write performance of the LUN has greatly improved the performance of the LUN
• B.  The data on a single LUN is distributed to many different hard disks, avoiding hard disk hot spots, making single LUN performance and The capacity has been greatly improved
• C.  The data is automatically and evenly distributed on the hard disks in the storage pool to avoid uneven heating and cooling of the hard disk, thereby reducing the storage system Overall failure rate
• D.  Overcome the performance bottleneck of the traditional RAID reconstruction target disk (hot spare disk), making the reconstruction bandwidth write bandwidth no longer It becomes the bottleneck of the reconstruction speed, which greatly improves the reconstruction speed, reduces the probability of double-disk failure, and improves the storage system.
  Reliability.

The following description of common storage protocols is correct?

• A.  The ATA protocol uses a parallel interface, which can only be built-in and requires cable length
• B.  A SAS domain can connect 15 devices
• C.  FC protocol has good compatibility and long transmission distance
• D.  The SCSI protocol does not support hot swap

The steps of asynchronous remote replication multi-point technology, is the following statement correct?
(1) A new time slice (T2, P2) is generated in the cache of the master LUN and the slave LUN at the start of each replication cycle (2) The newly written data of the host is cached in the time slice T2 of the main LUN Cache, responding to the completion of the host (3) The master and slave LUNs each release the received data (4) Copy the data of time slice T1 directly to the slave LUN and write it to the time slice P2 of the slave LUN

Which of the following statements about Disaster Recovery is NOT true?

• A.  After a disaster access to the data, on the remote site, can be immediate.
• B.  Applications to work with the recovered data is in place.
• C.  Some data loss must be accepted.
• D.  There are still traditional backup strategies in place.

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.
