NEW QUESTION 244
In Huawei RAID 2.0+, is the description about chunck and extent correct?
- A. chunck is the smallest unit for LUN to apply for space from the storage pool and free up space
- B. The extent is the smallest unit for the storage pool to allocate resources from the hard disk domain
- C. The extent size of different storage pools can be different, but the extent size in the same storage pool is uniform
- D. chunck is the smallest unit of hot data statistics and migration (data migration granularity)
Answer: C
Explanation:
Explanation
Analysis: extent is a fixed-size logical storage space divided on the basis of CKG, the size is adjustable, and it is a hot data system.
The smallest unit of accounting and migration (data migration granularity) is also the smallest unit of applying space and releasing space in the storage pool. Do not The extent of the same storage pool can be different, but the extent of the same storage pool is uniform.
CKG is a logical storage unit composed of CKs from different hard drives in the same DG according to the RAID algorithm.
The smallest unit of resources allocated by the pool from the hard disk domain.

NEW QUESTION 250
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.
