Chapter IX. Data Center Bridging (DCB)

1. 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 bandwith 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.
