DSS is a hardware and software complex for data storage and processing. The standard hardware architecture of DSS is a set of drives, controller and cache memory in the housing with one or more power supplies. Software is represented by management systems, backup technologies, compression and virtualization programs.
The main advantage of DSS over a standard server is the higher speed of disk systems. This allows you to significantly increase system performance when you need to process a large amount of information.
Data storage technologies are optimized to save disk space through compression and deduplication. Compression condenses stored files, while deduplication eliminates unnecessary files, leaving only references to them. Modern networking technologies allow efficient consolidation of storage systems into storage networks.
