Question

What Storage Area Network (SAN) protocol runs on top of TCP, and can be used on an existing twisted-pair Ethernet network, while maintaining low cost?

a.
Internet SCSI (iSCSI)
b.
InfiniBand (IB)
c.
Fibre Channel (FC)
d.
Fibre Channel over Ethernet (FCoE)

Answer 1

a. Internet SCSI (iSCSI)

Step-by-step explanation:

Internet SCSI or iSCSI is a storage area network(SAN) protocol which runs on top of TCP/IP and can be used for interfacing with storage devices using SCSI (Small Computer System Interface) commands. iSCSI can be used on existing twisted pair Ethernet network which is less costly than a corresponding fibre optic network. This helps reduce the total cost of deployment in a SAN environment.
