What are the differences between FC and FCoE technology?

Fiber Channel (FC) is a serial data transfer protocol and standard for high-speed enterprise-grade storage networking. It supports speeds up to 128 Gbps and delivers storage data over fast optical networks. FCOE maps Fiber Channel over full duplex Ethernet networks based IEEE 802.3 standard.

How fast is FCoE?

FCoE makes it possible for such an organization to achieve higher speeds such as 10 Gbps or 40 Gbps by using comparatively inexpensive Ethernet networks. Simplified network management.

What are the components of FCoE?

FCoE requires the deployment of three new components: a Converged Network Adapter (CNA), Lossless Ethernet Links, and a Converged Network Switch (CNS). The CNA provides the functions of both a standard NIC and a FC HBA in a single adapter in the server.

Is FCoE faster than iSCSI?

From a performance perspective, iSCSI lags behind FC/FCP. But when iSCSI is implemented properly, the difference boils down to a few milliseconds of additional latency due to the overhead required to encapsulate SCSI commands within the general-purpose TCP/IP networking protocol.

Why is FCoE not routable?

FCoE operates directly above Ethernet in the network protocol stack, in contrast to iSCSI which runs on top of TCP and IP. As a consequence, FCoE is not routable at the IP layer, and will not work across routed IP networks.

What is the difference between FCIP and FCoE?

FCIP is about the wrapping of FC frame into a TCP stream for reliably transporting FC Frames over an IP network, which is used for things like SAN to SAN replication over a WAN. FCoE unifies enterprise Data and storage into a single “converged” network.

Is FCoE routable?

FCOE is non Routable. We require FCIP to extend or join FCoE SANs, even over short distances. High cost since requires dedicated active and passive infrastructure to support FC (SAN) traffic.

Is iSCSI same as Ethernet?

Because it uses standard Ethernet, iSCSI does not require expensive and sometimes complex switches and cards that are needed to run Fibre Channel networks. That makes it cheaper to adopt and easier to manage.

Does FCoE use IP?

FCoE, though uses Ethernet, does not uses TCP or IP (unlike iSCSI, which is also Ethernet based and it does use TCP-IP).
