1 Data Center Bridging https://store.theartofservice.com/the-data-center-bridging-toolkit.html

2 IEEE 802.3 - Communication Standards 1 802.3bd2010Priority-based Flow Control. An amendment by the IEEE 802.1 Data Center Bridging Task Group (802.1Qbb) to develop an amendment to IEEE Std 802.3 to add a MAC Control Frame to support IEEE 802.1Qbb Priority-based Flow Control. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

3 Ethernet flow control 1 The follow-on 'priority-based flow control', as defined in the 'IEEE 802.1Qbb' standard, provides a link-level flow control mechanism that can be controlled independently for each Class of Service (CoS), as defined by IEEE P802.1p. The goal of this mechanism is to ensure zero loss under congestion in data center bridging (DCB) networks. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

4 Ethernet flow control - Priority flow control 1 The effort was part of the data center bridging task group, which developed Fibre Channel over Ethernet. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

5 Data center bridging 1 'Data center bridging' (DCB) refers to a set of enhancements to Ethernet local area networks for use in data center environments https://store.theartofservice.com/the-data-center-bridging-toolkit.html

6 Data center bridging 1 To meet these goals new standards are being (or have been) developed that either extend the existing set of Ethernet protocols or emulate the connectivity offered by Ethernet protocols. They are being (or have been) developed respectively by two separate standards bodies, the Institute of Electrical and Electronics Engineers (IEEE) Data Center Bridging Task Group of the IEEE 802.1 Working Group and the Internet Engineering Task Force (IETF). https://store.theartofservice.com/the-data-center-bridging-toolkit.html

7 Data center bridging - Terminology 1 Different terms have been used to market products based on data center bridging standards: https://store.theartofservice.com/the-data-center-bridging-toolkit.html

8 Data center bridging - Terminology 1 * 'Data Center Ethernet' (DCE) was a term trademarked by Brocade Communications Systems in 2007 but abandoned by request in 2008. DCE referred to Ethernet enhancements for the Data Center Bridging standards, and also including a Layer 2 Multipathing implementation based on the IETF's TRILL (computing)|Transparent Interconnection of Lots of Links (TRILL) standard. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

9 Data center bridging - Terminology 1 ** The [ http://www.ieee802.org/1/files/public/docs2 008/az-wadekar-dcbx-capability- exchange-discovery-protocol-1108- v1.01.pdf Data Center Bridging eXchange (DCBX) Version 0 Specification] was also submitted for use in the [ http://www.ieee802.org/1/pages/802.1az.ht ml IEEE 802.1Qaz] project. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

10 Data center bridging - IEEE Task Group 1 * Data Center Bridging Capabilities Exchange Protocol (DCBX): a discovery and capability exchange protocol that is used for conveying capabilities and configuration of the above features between neighbors to ensure consistent configuration across the network. This protocol leverages functionality provided by [ http://www.ieee802.org/1/pages/802.1ab.html IEEE 802.1AB] (LLDP). It is actually included in the 802.1az standard. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

11 Brocade Communications - Products 1 Other hardware solutions from Brocade support common protocols including iSCSI, FCIP, GigE, FICON, Fibre Channel over Ethernet|FCoE, Data center bridging|DCB/CEE, and Layer 4-7 networking protocols. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

12 Brocade Communications - Fibre Channel 1 In Late 2010 Brocade introduced Virtual Cluster Switching (VCS) on the VDX ultra- low-latency data center switch product line. These are Data center bridging|DCB/CEE- and TRILL (Computer Networking)|TRILL-based switches, eliminating the need for Spanning Tree Protocol, and supporting multi-hop Fibre Channel over Ethernet (FCoE) and self- trunking. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

13 Ethernet Alliance - Organization 1 * Ethernet in the Data Center focus includes protocols such as Data Center Bridging (DCB), Fibre Channel over Ethernet (FCoE), iSCSI, Remote direct memory access over Converged Ethernet (RoCE) and iWARP. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

14 Link Layer Discovery Protocol - Applications 1 The Link Layer Discovery Protocol may be used as a component in network management and monitoring applications. One such example is its use in data center bridging requirements. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

15 FCoE - Functionality 1 Since classical Ethernet had no priority- based Ethernet flow control|flow control, unlike Fibre Channel, FCoE required enhancements to the Ethernet standard to support a priority-based flow control mechanism (to reduce frame loss from congestion). The IEEE standards body added priorities in the data center bridging Task Group. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

16 Dell PowerConnect - 8100 series 1 It is a small (1U) switch with a high port- density and can be used as distribution or (collapsed)core switch for campus networks and for use in the datacenter it offers features such as loss-less ethernet for iSCSI and FCoE, data center bridging (DCB) and iSCSI Auto-configureDell [http://i.dell.com/sites/doccontent/shared- content/data- sheets/en/Documents/Dell_PowerConnect_8 100_Series_Spec_Sheet.pdf PowerConnect 8100 spec sheet], July 2012 https://store.theartofservice.com/the-data-center-bridging-toolkit.html

17 Dell M1000e - I/O Aggregator 1 The I/O aggregator supports Fibre Channel over Ethernet|FCoE and DCB (Data center bridging) featuresDell website: [http://www.dell.com/us/business/p/powere dge-m-io-aggregator/pd#TechSpec PowerEdge M I/O Aggregator], August, 2012 https://store.theartofservice.com/the-data-center-bridging-toolkit.html

18 LIO Target - FCoE 1 The Fibre Channel over Ethernet (FCoE) fabric module allows the transport of Fibre Channel protocol (FCP) traffic across data center bridging|lossless Ethernet networks. The specification, supported by a large number of network and storage vendors, is part of the Technical Committee T11 FC-BB-5 standard. https://store.theartofservice.com/the-data-center-bridging-toolkit.html

19 Dell Networking - Dell Networking S series 1 The S-5000 is targeted for datacenter networking as either a 10G access-switch or a datacenter distribution switches. It can also be used as (routing) core switch in smaller datacenters. It fully supports Data Center Bridging (DCB) and can also be used as FCoE or Fibre Channel switch by using a FC interface module. https://store.theartofservice.com/the-data-center-bridging-toolkit.html
