Data Center Bridging Technology Overview

The Dell Networking N4000 switches support Data Center Bridging (DCB)
features to increase the reliability of Ethernet-based networks in the data
center.
The N4000 switches support PFC, ETS, and DCBX capability exchange, with
the ability to autoconfigure from a peer switch.
The Ethernet enhancements that DCB provides are well suited for iSCSI
applications.
Table29-1 provides a summary of the features this chapter describes.
NOTE: The data center fatures described in this chapter are available on the Dell
Networking N4000 switches only.
