About Huawei 2.0+ advantage, Which description is correct? (Multiple choice)
A . data on the hard disk storage pools automatically load balancing, avoiding hard disk uneven cold and heat, thus reducing the failure rate of storage system as a whole
B . overcome the target disk (hot standby) performance bottlenecks of traditional RAID reconstruction , making the reconstructed data stream write bandwidth is no longer a bottleneck of reconstructed speed, thereby greatly enhancing the reconstruction speed and reduces the double disk failure probability, enhance the reliability of the storage system
C . There is no writing punishment in RAID2.0+ , overcome the impact of writing punishment to LUN writing performance of RAID5 and RAID6 level in the traditional RAID technology ,lead to a single LUN performance improved dramatically.
D . data on a single LUN distributed to many different hard disk, to avoid the hard disk hotspot, lead to a single LUN performance and capacity has been increased dramatically.
