Chapter XIII. Data Center Bridging (DCB) 

Chelsio Unified Wire for Linux 

 212

 

 Introduction 

Data Center Bridging (DCB) 

refers to a set of bridge specification standards, aimed to create a 

converged  Ethernet  network  infrastructure  shared  by  all  storage,  data  networking  and  traffic 
management  services.  An  improvement  to  the  existing  specification,  DCB  uses  priority-based 
flow control to provide hardware-based bandwidth allocation and enhances transport reliability.  

One of DCB’s many benefits includes low operational cost, due to consolidated storage, server 
and networking resources, reduced heat and noise, and less power consumption. 
Administration is simplified since the specifications enable transport of storage and networking 
traffic over a single unified Ethernet network.
