Explanation

Disk drives (D) are the back-end hardware components that physically store the actual data in VSP midrange storage systems - they are the persistent storage medium that retains data even when power is removed. Storage controllers (A) are the "brain" that manage data flow and processing but don't store data themselves. Cache memory (B) is temporary, high-speed RAM used to buffer I/O operations and improve performance, not for permanent storage. Network interface cards (C) handle external connectivity to hosts and networks, not data storage.

Memory tip: Think of the storage system like a library - the disk drives are the bookshelves (where data actually lives), the controllers are the librarians (who manage access), and cache is the checkout desk (temporary holding area). Back-end = where data is kept long-term = disk drives.
