If you are interested in it, then you should read this post carefully.
This post is mainly talking about FCoE (Fibre Channel over Ethernet).
it’s possible for you to know FCoEs definition, functionality, program, and frame format.
Definition of FCoE
What is FCoE?
This specification was part of the International Committee for Information Technology Standards T11 FC-BB-5 standard released in 2009.
Functionality of FCoE
FCoE is independent of Ethernet forwarding schemes and directly transmits Fibre Channel over Ethernet.
The FCoE protocol specification replaces the FC0 and FC1 layers of the Fibre Channel stack with Ethernet.
Data centers utilized Ethernet for TCP/IP networks and Fibre Channel forstorage area networks (SANs).
Compared withiSCSIrunning onTCPand IP, FCoE runs directly on Ethernet in the connection protocol stack.
The IEEE standards body added priorities to the Data Center Bridging (DCB) task group.
CNA has one or more physical Ethernet ports.
Because FCoE can reduce cabling, it has special applications in data centers.
In server virtualization applications, FCoE usually requires many physical I/O connections for each server.
This combination can:
Frame Format of FCoE
FCoE uses dedicated Ethertype 0x8906 to encapsulate over Ethernet.
A single 4-bit field (version) meets the IEEE subtype requirements.
The 802.1Q tag is optional but may be necessary for a given implementation.
The reserved bit is used to ensure that the FCoE frame meets the minimum length requirement of the Ethernet.
FIP (FCoE Initialization Protocol) is an integral part of FCoE.
Its main goal is to discover and initialize FCoE-enabled entities connected to the Ethernet cloud.
FIP uses the dedicated Ethertype of 0x8914.
Advantages of FCoE
Using Fibre Channel over Ethernet has many advantages, including:
