Which of the following storage technologies operates over IP?

Which of the following storage technologies operates over IP?

• A. SCSI
• B. DAS
• C. FCP
• D. NAS

Answer: (A)

The correct answer is NAS, which stands for Network-Attached Storage. NAS operates over IP (Internet Protocol) and allows multiple users and devices to access and share files over a network. It provides a centralized storage solution that connects directly to a network, enabling user access through standard networking protocols, such as TCP/IP. This makes NAS particularly suitable for collaborative environments where data needs to be shared among multiple clients and devices. In contrast, SCSI (Small Computer System Interface) primarily connects directly to storage devices over a physical interface, functioning at the hardware level without utilizing IP. DAS, or Direct-Attached Storage, connects storage devices directly to a server or computer without a network, thus also not using IP. FCP, or Fibre Channel Protocol, is a high-speed network technology for connecting storage devices but operates over Fibre Channel networks rather than IP. Therefore, NAS is the only technology among the choices provided that operates over IP, allowing for flexible, network-based storage solutions.
