Question 7

Which of the following statements is false about centralized storage and distributed storage?

A. Centralized storage has a simple deployment structure. It can leverage the redundant array of independent disks (RAID) technology to ensure data security and reliability. B. Distributed storage stores data on multiple independent devices. During data reading, data is read from these devices at the same time, affecting read efficiency. C. Distributed storage adopts a scalable system architecture and enables multiple storage servers to share the storage load, improving scalability, reliability, availability, and access efficiency. D. In terms of technical architectures, centralized storage can be classified into network attached storage (NAS) and storage area network (SAN). SANs are further divided into Fibre Channel storage area networks (FC SANs) and IP storage area networks (IP SANs).
