  • 1. FABRICS AND THE CLOUDREINVENTING THE DATA CENTER NETWORKAndy IngramSVP, Juniper NetworksSeptember, 2011
  • 2. NEW MATH 2096 - 800 = 1296 Federal Data Centers Mandated reduction Future capacity 2096 x 61%* = 1279 Federal Data Centers Average utilization Current requirements 1279 x 1.37 * = 1752 Federal Data Centers Expected increase Future requirements in required capacity 1296 = 1752 /2 Copyright © 2011 Juniper Networks, Inc. www.juniper.net * Per MeriTalk survey of 200 Federal IT decision makers – June 2011

SKEPTICISM OR REALISM 23% 10% anticipate there will be of Federal IT more rather than fewerprofessionals believe the data centers in 2015 Feds will reach or exceed the 2015 goal3 Copyright © 2011 Juniper Networks, Inc. www.juniper.net Per MeriTalk survey of 200 Federal IT decision makers – June 2011

  • 28. DATA PLANE IN A SINGLE SWITCH Data Plane 1. The line cards contain the ports and processing intelligence 2. The fabric cards interconnects all ports – any-to-any 3. A single “full lookup” processes the packets29 Copyright © 2011 Juniper Networks, Inc. www.juniper.net
  • 29. SINGLE SWITCH DOES NOT SCALE Ports can be added to a single switch fabric. …but eventually it runs out of real estate. After this, the network cannot be flat.30 Copyright © 2011 Juniper Networks, Inc. www.juniper.net
  • 30. SINGLE SWITCH DOES NOT SCALE Sacrifice simplicity or… Choice: change the scaling model31 Copyright © 2011 Juniper Networks, Inc. www.juniper.net
  • 31. SCALING THE DATA PLANE Interconnect vs Switch So, we separate the Bandwidth: 10 Tb/s from the fabric. line cards vs 2.5 Tb/s And extend the copper Power: traces with fiber 13 Kw 3 Kw vs links. For redundancy add ASICs in DP: multiple devices. 5 3 vs Latency: 2 us vs 10 us QF/Interconnect QF/Node32 Copyright © 2011 Juniper Networks, Inc. www.juniper.net
  • 32. SCALING THE DATA PLANE Benefits: • Flatter topology 1. All portsconnected directly are • Virtualizes locality to every other port • Eliminates STP, TRILL, SPB QF/Interconnect 2. A single “full lookup” at the • Efficiency (less hardware) ingress QF/Node • Less power, space, cooling device • Faster (lower latency, jitter) QF/Node • Simpler (N=1) • Less expensive 3. Blazingly fast: Always under 5us 3.71us (short cables) QFabric is faster than any Ethernet chassis switch ever built33 Copyright © 2011 Juniper Networks, Inc. www.juniper.net
