  7. 7. Traditional DC Network • Separated networks (LAN, SAN) • Hierarchical networks • Physical modules – LAN, SAN, FW, LB… • Complicated service introduction – IP-based (L3 devices,IP-rules, etc) – Difficult geo-extendibility – Limited flexiblity • Main DC equipment vendors in Israel – LAN : Nortel, Cisco, Avaya, Juniper, HP… – SAN/NAS : NetApp, EMC… – LB: Radware, Cisco, Nortel… – FW: Checkpoint, Juniper,Cisco..

  11. 11. NG DC Challenges• What do we want? – TB-ready, unified, flexible, secured, reliable and geo- extendable infrastructure – Unified LAN & SAN – Single point of management (even in geo-spread DC-es) – Logical (Virtual) move & change of DC entities• What are the enemies of NG DC? – Insufficient backplane of traditional switches – Unreliable & slow Ethernet – Spanning Tree – L3 segmentation (DC, WAN) Radia Perlman Comm-IT 2011 - All Rights Reserved 12
  12. 12. NG DC Standards • Bandwidth – IEEE 802.3ae/ak/an – 10G Ethernet – IEEE 802.3ba - 40G/100G Ethernet • SAN & LAN Unification – FCoE (INCITST11FC-BB-5) – iSCSI • Reliable Ethernet: – DCB (Data Center Bridging)/ CEE (Converged Enhanced Ethernet) • 802.1QbbPFC (Priority-based Flow Control) • 802.1QazETS (Enhanced Transmission Selection) • 802.1QuaCN (Congestion Notification) • DCBX (DCB Capability Exchange) – similar to LLDP • Anti-STP: – IEEE 802.1aq/SPB (Shortest-path bridging) – IETF TRILL (Transparent interconnection a lot of links) • Interoperability – IEEE 802.1Qbg EVB (Ethernet Virtual Bridging) – VM Switch interop – IEEE 802.1Qbh BPE (Bridge Port Extension) – Port Extenders interop – Inter-Fabric protocol in process (TBD – based on ICCP ?) – MLAG (TBD - based on 802.3AX-2008) Comm-IT 2011 - All Rights Reserved 13
  13. 13. What wrong with L3 in DC? Moving VM is night-mare )IP/DG/VLAN/QOS/Policy… change( R R R R R R SF1 SF2 … SF3 now move itSF4 to L3 L3 L3 other L3 DC site DRP L3 BB1 R R BB2 What if you have … and ADC?? also Classic FW? WAN Module Comm-IT 2011 - All Rights Reserved 14
  14. 14. Solution – Flat L2 DC Core• But… – Now I have a lot of STP loops and broadcasts !!! – What about security and application delivery?? L2 L2 L2 L2 L2 R R WAN Module Comm-IT 2011 - All Rights Reserved 15
  15. 15. Anti-STP: TRILL vs SPB• TRILL – IETF – Based on IS-IS – L3 Protocol – Requires h/w change – More reliable• SPB – IEEE Radia Perlman – Based on IS-IS 16 – SPBV & SPBM – L2 Protocol – No h/w change Comm-IT 2011 - All Rights Reserved 16 Source: NIL
