A storage administrator needs to implement SAN-based shared storage that can transmit at 16Gb over an optical connection. Which of the following connectivity options would BEST meet this requirement?
Fibre Channel is a connectivity option that can transmit at 16Gb over an optical connection for SAN-based shared storage. Fibre Channel is a high-speed network technology that provides reliable and secure data transfer betweenservers and storage devices. Fibre Channel uses optical fiber cables to connect devices and supports various topologies and protocols. FCoE is another connectivity option that uses Fibre Channel over Ethernet, which encapsulates Fibre Channel frames into Ethernet packets. FCoE can also transmit at 16Gb over an optical connection, but it requires a converged network adapter (CNA) and a lossless Ethernet network. iSCSI is another connectivity option that uses SCSI commands over IP networks, which can use either copper or optical cables. iSCSI can transmit at 10Gb or 40Gb over an optical connection, but it has higher latency and lower performance than Fibre Channel. eSATA is another connectivity option that uses SATA commands over external cables, which are usually copper. eSATA can transmit at 6Gb over a copper connection, but it has limited cable length and device support compared to Fibre Channel.
