Data Center Ethernet

Introduction

Data Center Ethernet is a standards-based, high-performance, enhancement to classical Ethernet that supports the business, service, application, and operational requirements of next-generation data centers.

Specifically, Data Center Ethernet provides the operational characteristics, architectural scalability and transport flexibility required to meet the demands of these next-generation data centers through a collection of standards-based extensions to Ethernet. Data Center Ethernet allows data center architects to create a data center transport layer that is:

  • Lossless
  • Stable
  • Efficient

This is a prerequisite to implement a unified data center fabric with Fibre Channel over Ethernet, but is also valuable for implementing iSCSI or any other business-critical traffic.

Data Center Ethernet is an architectural collection of Ethernet extensions designed to enhance Ethernet networking and management specifically in data center environments. Cisco has pioneered and is leading the development of key concepts and facilities within IEEE and ANSI T.11 to develop and promote data center Ethernet standardization to facilitate multivendor, interoperable solutions to data center challenges.

Data Center Ethernet includes the following capabilities:

  • Class based flow control (CBFC)
  • Enhanced transmission selection (ETS) (IEEE 802.1Qaz )
  • Data center bridging capability exchange protocol (DCBCXP)
  • Lossless Ethernet
  • Congestion notification (IEEE 802.1Qau)

Data Center Ethernet is a flexible framework that defines the requirements for switches and end points. This enables devices to support only a subset of capabilities listed above that are required to be part of a Data Center Ethernet fabric.
