Regarding the advantages of Huawei RAID 2.0+, which of the following is correct? (Multiple choice)
- A. The data is automatically and evenly distributed on the hard disks in the storage pool, avoiding unevenness of the hard disks, thereby reducing the overall failure rate of the storage system
- B. Overcoming the performance bottleneck of the target disk (hot spare disk) of traditional RAID reconstruction, so that the write bandwidth of the reconstructed data stream no longer becomes the bottleneck of the reconstruction speed, which greatly improves the reconstruction speed and reduces the failure of double disks.
