A.TRUE

B.FALSE

A.RAID 6 (8D+2P)

B.RAID TP (7D+3P)

C.RAID 5 (9D+1P)

D.RAID 1

Question 23

Question 24

Which statements about storage arrays are correct?

A.A storage array consists of multiple disks used as a single disk. It stores data in segments an different disks When data is stored, the related disks in the array work together to reduce the time required for storage and improve the space utilization.

B.A controller is the brain of a storage array and its main components are a processor and cache.1/0 operations and RAID management functions are implemented first With the development of technologies, data management functions such as snapshot, mirroring, and replication are provided.

C.Cache buffers host data in a storage system and improves the performance and reliability of the storage system.

D.Intelligent cache prefetch identifies the access mode of a host predicts the data to be accessed, and reads the data from disks in advance to improve the cache hit ratio.

Question 25

SSDs+NL-SAS HDDs are recommended for the new-gen OceanStor hybrid flash storage. No SAS HDDs are required.
