Converged Data Center: FCoE, iSCSI and the Future of Storage Networking

1,321 views

Published on

From ( EMCWorld 2011 ) : This session explores the opportunities and challenges of using a single network to support both storage and networking. The Fibre Channel over Ethernet (FCoE) and iSCSI (SCSI over TCP/IP) protocols offer two approaches for supporting storage over Ethernet. Standards, technologies and deployment scenarios for both protocols are covered, along with the future of storage networking technology.

  16. 16. FCoE Initialization ProtocolEthernet is more than a cable•  Native Fiber Channel link: Fiber has exactly 2 endpoints (simple) –  Discovery: Who is at the other end? •  Response to FC login contains answer –  Liveness: Is the other end still there? •  Is the optical link lit and synchronized?•  FCoE virtual link: Ethernet LAN or VLAN has more than 2 endpoints –  Discovery: Choice of endpoints (FCoE switches) •  Where should the FC login be sent? –  Liveness: FCoE virtual link may span multiple Ethernet links •  What if attached link is ok, but some other link is not?•  FCoE configuration concern: Do mini jumbo frames (2.5k) work?•  FIP: FCoE Initialization Protocol –  Discover other endpoint, create and initialize virtual link with FCoE switch –  Mini jumbo frame support: Large frame is part of discovery –  Periodic LKA (Link Keep Alive) messages after initialization© Copyright 2011 EMC Corporation.

  17. 17. FCoE Switch Discovery FCoE/FCStep 1: FIP Solicitation Switches Server DCB FC SAN Ethernet SolicitationŸ  Select FCoE VLAN first (pre-configured or use FIP)Ÿ  Solicitation is multicast: Server can discover multiple switchesŸ  Solicitation identifies Server (FC WWN for FCoE CNA) –  CNA = Converged Network Adapter (FCoE analog of HBA) –  Switch may choose which servers to respond to (default: respond to all)© Copyright 2011 EMC Corporation.

  18. 18. FCoE Switch Discovery FCoE/FCStep 2: FIP Advertisement Switches Server DCB FC SAN Ethernet Advertisement Priority = 1 Advertisement Priority = 25Ÿ  Advertisement identifies switch (FC WWN) –  Multiple switches may respond, advertisement includes priority –  Server chooses FCoE switch by priority (smallest number wins)Ÿ  Advertisement padded to max FC frame size: Test mini jumbo frame support© Copyright 2011 EMC Corporation.

  19. 19. FIP Switch Discovery FCoE/FCStep 3: FIP-based FC Login Switches Server DCB FC SAN Ethernet FLOGI Priority = FLOGI 1 ACC Priority = 25Ÿ  FIP encapsulated FC Login –  Server sends FC Fabric Login (FLOGI) to selected switch –  Switch responds with FC FLOGI ACC (accept) that contains assigned FCIDŸ  Subsequent traffic: Standard FC frames (FCoE encapsulated)© Copyright 2011 EMC Corporation.

  43. 43. Summary•  Converged data center environments can be built using 10Gb Ethernet•  Achieving a converged network requires consideration of technology, processes/best practices and organizational dynamics•  10 Gigabit Ethernet solutions are maturing –  Active industry participation is creating standards that allow solutions that can integrate into existing data centers –  Continued use of FC and adoption of FCoE can be flexible due to shared management –  FCoE and iSCSI will follow Ethernet roadmap to 40 and 100 Gigabits/sec© Copyright 2011 EMC Corporation.
