"There are number of discussions, blogs, and articles comparing Internet SCSI (iSCSI), Fibre Channel over Ethernet (FCoE), and Fibre Channel (FC). Many of them share a common belief that FCoE and FC are better suited as core data center storage area networks (SANs) and that iSCSI is ideal for Tier 2 storage or for SAN deployments in remote or branch office (ROBO) and small and medium business (SMB) environments. That is because iSCSI is characterized as “low-performing,” “lousy,” and “unpredictable.” In this blog I will tackle the misinformation around iSCSI performance as compared to FC and FCoE. I will also compare effective efficiency of the various SAN protocols since efficiency is an aspect of performance."
"Fibre Channel over Ethernet (FCoE) is an encapsulation of Fibre Channel frames over Ethernet networks. This allows Fibre Channel to use 10 Gigabit Ethernet networks while preserving the Fibre Channel protocol[1]. The specification, supported by a large number of network and storage vendors, was developed by the FC-BB-5 working group of T11. On June 4, 2009, T11 approved the FC-BB-5 Draft Standard and forwarded it to INCITS for the publication process as an ANSI standard."
