What is the function of iSCSI as compared to Fibre Channel?

The function of iSCSI primarily revolves around its capability to utilize TCP/IP for transmitting SCSI commands over a network, making it compatible with existing Ethernet infrastructure. This allows for a more flexible and cost-effective solution for storage area networks, as organizations can leverage their existing network equipment and architecture without the need for specialized Fibre Channel switches and cabling.

Since iSCSI operates over standard Ethernet networks, it benefits from the widespread availability of TCP/IP technology. This contrasts with Fibre Channel, which requires a more specialized setup that can be more complex and expensive to implement. As a result, iSCSI is often used in environments where cost efficiency and ease of integration are paramount.

While other options may touch upon different aspects of iSCSI and Fibre Channel, the core strength of iSCSI lies in its utilization of TCP/IP, enhancing its accessibility and ease of use in modern networking environments.
