Distributed Storage Systems

As data volume continues to increase, a single server fails to meet the storage requirements of applications. Therefore, distributed storage systems have come into being. These systems connect a large number of servers over a network, distribute data across these servers, and provide specific storage interfaces for upper-layer applications. In addition to standard server hardware, many companies have developed dedicated hardware for distributed storage systems to achieve higher reliability and performance, lower costs, and energy saving. Based on storage interface classification, common distributed storage systems include distributed key-value store systems, distributed object storage systems, distributed block storage systems, and distributed file systems.
