State of the union

  1. 1. 1© 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential© 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 1State of the Union for Fibre Channel and FibreChannel over Ethernet StandardsJ MetzCo-Sponsoredby Intel®
  2. 2. 2© 2013 Cisco and/or its affiliates. All rights reserved. Cisco PublicWhats New in the Fibre Channel and FCoE WorldAgendaNew ways to connect devices togetherNew ways to zoneNew ways to architect topologies
  3. 3. 3© 2013 Cisco and/or its affiliates. All rights reserved. Cisco PublicFirst Things First!How to Use StandardsStandards are designed to solve a particular problemIf you dont have that problem, you dont need astandard way to solve it!

  5. 5. 5© 2013 Cisco and/or its affiliates. All rights reserved. Cisco PublicThe Grand-daddy of FCoE StandardsFC-BB-5Allows you to put Fibre Channel frames onto Ethernet topologiesCan duplicate Fibre Channel topologiesRequires a "Fibre Channel Forwarder" (FCF) somewhere-Devices need to be connected either directly or indirectly through a FIP-Snooping Bridge
  6. 6. 6© 2013 Cisco and/or its affiliates. All rights reserved. Cisco PublicAdding more tools to the toolboxFC-BB-6"How do you connect an initiator and atarget without using an FCF?"-BB6 Answer: PT2PT; VN2VN"How do you address scalabilityquestions of Domain ID sprawl"-BB6 Answer: FCoE Data-Plane Forwarder(FDFs)
  7. 7. 7© 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential© 2010 Cisco and/or its affiliates. All rights reserved. Cisco ConfidentialNew Ways to Connect with FCoEVN2VN and PT2PT7
  8. 8. 8© 2013 Cisco and/or its affiliates. All rights reserved. Cisco PublicHow do you connect an initiator directly to a target?PT2PTIf you want to connect two devices-And only two!Like Fibre Channel, can connect directlytogether-Same thing as FC point-to-pointUnlike Fibre Channel, can be connectedthrough a (lossless DCB Ethernet) bridgeDCB Cloud
  9. 9. 9© 2013 Cisco and/or its affiliates. All rights reserved. Cisco PublicPlusses and MinusesPT2PTPlus:-No switch needed-Very fast initialization-Useful for Mainframe environments-Designed to support any two ports in a L2segment-Can operate independently of the type of LinkAggregation usedMinus:-No protection provided by zoning-No notification via RSCN if other devicesshould disappear or re-appear-Dependent on Link Keepalives (LKAs) andAdvertisements for discoveryDCB Cloud

  11. 11. 11© 2013 Cisco and/or its affiliates. All rights reserved. Cisco PublicPlusses and MinusesVN2VNPlusses-No switch needed-Designed to support any two ports in a L2segment-Can operate independently of the type ofLink Aggregation usedMinuses-Same limitations as PT2PT, plus...-Each VN_Port needs to keep track of alllogins•I.e., each node keeps a copy of the entirename server-Each login takes time•"Multiple" devices doesnt mean "many"devicesFCoEInitiatorsFCoETargets

  24. 24. 24© 2013 Cisco and/or its affiliates. All rights reserved. Cisco PublicWhat If... We only had RSCNs communicated between the host and the target its logged into? The target told the switch to only send RSCNs to its logged-in hosts? Come to think of it...– The target has a list of approved hosts anyway– Why not have it tell the switch to create a zone based on that info? Its so crazy it might just work!– ... and it does!Zoneset:WWN1WWN2WWN3...WWN1WWN2WWN3Zone "TDZ"
