A storage protocol is a set of rules and standards that govern how data is stored, accessed, and managed in storage systems. These protocols ensure that different devices and applications can communicate effectively, allowing for efficient data transfer and retrieval. Common storage protocols include NFS (Network File System), iSCSI (Internet Small Computer Systems Interface), and SMB (Server Message Block). These protocols play a crucial role in various environments, from personal computers to large data centers. They help maintain data integrity, optimize performance, and facilitate backup and recovery processes. By adhering to these standards, organizations can ensure compatibility and reliability in their storage solutions.
