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

• A.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
• B.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.
• C.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
• D.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
