Which of the following is considered a SAN protocol?

  1. FCP

  2. IDE

  3. SSD

  4. DTE

The correct answer is: FCP

FCP, or Fibre Channel Protocol, is a key protocol used in Storage Area Networks (SANs). It enables the transmission of data between servers and storage devices over a high-speed Fibre Channel network. FCP is designed specifically for SAN environments, where speed and efficiency in handling storage requests are critical. In contrast, IDE (Integrated Drive Electronics) refers to a standard interface for connecting storage devices to a computer, mainly using parallel signaling, which does not operate within a SAN framework. SSD (Solid State Drive) and DTE (Data Terminal Equipment) also do not apply as SAN protocols; SSD is a type of storage technology, and DTE is a term used to describe devices that provide data communication capabilities in serial communication systems. Thus, FCP stands out as the appropriate choice, being inherently tied to the functionalities and operations of SANs, facilitating efficient data transfer and storage management in those dedicated environments.
