Which protocol is most commonly associated with block storage in SAN implementations?

CIFS
NFS
iSCSI
HTTP

The correct answer is: iSCSI

The protocol most commonly associated with block storage in Storage Area Network (SAN) implementations is iSCSI. iSCSI, which stands for Internet Small Computer System Interface, enables the transmission of SCSI commands over IP networks. This makes it ideal for block storage, allowing servers to communicate with storage devices over a reliable and high-speed network infrastructure. iSCSI facilitates the creation of a SAN environment by utilizing standard TCP/IP networking, providing scalability and flexibility. This makes it suitable for environments where performance and efficiency are paramount. In contrast, protocols such as CIFS and NFS are typically used for file-level storage rather than block storage. They operate at a higher level of abstraction, allowing access to files over a network rather than directly interfacing with storage blocks. HTTP is primarily used for web traffic and data transfer over the internet, rather than for storage networking solutions. Thus, while these other protocols serve important roles in data management and accessibility, they do not align with the block storage approach of SAN implementations like iSCSI does.
