Please help me get this answer.


Q. Which statements about storage arrays are correct ?


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


(B). A controller is the brain of the storage array and it main components are processor and cache I/O 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 storage system and improves the performance and reliability of the storage system.


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