Impact on the Data Centre t Sustained year on year growth of new applications, servers and storage t Data Centres now being planned for 20 – 50 year lifespan t Cabling Infrastructure needs to be planned in accordance t Other issues that need to be taken into account n Future of Ethernet n Energy Consumption 17
Converged Enhanced Ethernet 18
The Current Situation t Existing DC applications n Ethernet n Fibre Channel n Infiniband 3 systems n n Difficult to manage n t more complex Higher cost (equipment, admin, maintenance) Ethernet struggling to compete above 1 Gbps n Low I/O throughput n High Latency n Unsuitable for storage applications & cluster computing 19
What is Converged Enhanced Ethernet? t New standards being developed by IEEE & IEFT n Priority Flow Control (IEEE 802. 1 Qbb) n Congestion Notification (IEEE 802. 1 Qau) n Shortest path bridging (IEEE 802. 1 aq) n Link Layer routing protocol (IETF – TRILL) n Enhanced transmission selection (IEEE 802. 1 Qaz) t Aim is to improve I/O throughput and reduce latency t Collectively called Converged Enhanced Ethernet or ‘Data Centre Ethernet’ 20
What Does This Bring The User? t Converged Enhanced Ethernet n Single unified network fabric l Easier management, admin, maintenance n Cheaper hardware costs n Plug & play features n Migration path to higher speeds n Long reach l Enables design flexibility l Improved load balancing/reduces hotspots l More efficient cooling 21

E (Fibre Channel over Ethernet) standard n Positions Ethernet as replacement for Infiniband through improved latency & I/O throughput 23
Carbon Reduction Commitment 24
Carbon Reduction Commitment t Government aim to reduce greenhouse gas emission n t 80% reduction by 2050 Who is targeted? n n ALL Companies using Half Hourly Metres usage >6000 MWhr in 2008 t Will indirectly impact ~20000 UK companies t Companies will have to buy & sell allowances. . . 25
Carbon Reduction Commitment t Estimated cost of typical consumption v allowance t Penalties and bonuses will be awarded depending on performance 26
Impact on the Data Centre t Data centres will be affected n Pressure to reduce power consumption But also. . . . t Demand for increased capacity at same time n Additional penalties are more likely to be incurred n Even more financial motivation to save cost 27
Options for DC owners? t Consolidation & virtualisation? n YES – both will help but. . . . l n CAPEX to invest will outstrip CRC penalties at some point Cluster computing poor load balance & hot spots inefficient energy use Additional actions will be required to prevent acceleration of energy growth 28
Energy Efficient Ethernet 29
Energy Efficient Ethernet t New Task Group formed to study ways to improve power consumption for Ethernet : “Energy Efficient Ethernet” t Idea: Idle Time of Ethernet is up to 90% = 90% waste of energy l “Reduce power when traffic goes down” l Down to 10% or even 0% of energy during idle time 30
Existing developments t 10 Gig standard already ‘accidentally’ includes some features to improve energy efficiency: n Power Back Off l Originally a ANEXT mitigation technique n Short Reach Mode l Theoretical means of reducing energy consumption 31
Power Back Off Long/Short Links server Long link switch Short link Signal attenuates over cable length High transmit power from near server induces high level Alien NEXT on weakened signal 32
Power Back Off Long/Short Links server Long link With Power Back Off switch Short link Transmit power reduced to a level where receive signal is OK. 33
Short Reach Mode t 86% of DC Server/switch links <30 m t Less noise cancellation and power required t Echo, NEXT, and FEXT cancellers account for ~ 40% of the chip power consumption t Coding elements account for ~ 25% t remaining 35% of the chip’s area is taken up for the AFE In links <30 m signal is analysed and cancellers are switched off. Better NEXT/FEXT means more cancellers can be switched off Requires better quality cabling. . . . 34
Auto Negotiation t Existing function but new enhancements t Match link rate to utilisation t turns off PHY’s at lower speed t Estimated savings n 1 Gbps 100 Mbps = 2 -4 watt saving n 2 watts x 8 NICs = 16 watts / server n x 1000 servers 16 kw/hr = 140 Mw/hrs = £ 10 k per year 35
Wake-on-LAN (WOL) t Industry tests show server uses 70% power when idle t WOL closes nearly all power during inactive periods t Only tiny level of residual ‘standby’ power required to escape from hibernation 36
Summary t Demand for bandwidth will increase t Need to plan for 40 G now t Ethernet set to become principle protocol n n t Unified LAN infrastructure EEE provide opportunity to reduce power consumption Increasing financial pressure to reduce energy consumption 37

Category 6 A Cat 6 A will: t support Switch to Server links to 2016 minimum t support Auto Negotiation at 10 G and below t support Power Back Off and WOL (Energy Efficient Ethernet) but. . 43
But. . . Cat 6 A won’t : t support 40 G over 100 m t offer more than limited throughput as an Ethernet platform for cluster computing and storage applications t support tangible power savings in Short Reach Mode Need better quality cabling. . . 44
Category 7 A 45
Category 7 A Cat 7 A will : t support Auto Negotiation at 40 G and below t support fully implemented Energy Efficient Ethernet n n WOL n t Short Reach Mode Power Back Off provide high throughput Ethernet platform for cluster computing and storage applications 46
LANmark-7 A Performance Capability t LANmark-7 A shown to have Shannon capacity of 52 Gbps various Nexans internal study groups n external studies (Source: Penn State University) n 47
LANmark-7 A What is it? t Cat 7 and GG 45 standardised in ISO since 2002 t Cat 7 A standardised 2008 -1000 MHz solution t Connectors n Nexans GG 45 (IEC 60603 -7 -71) l l Preferred solution in ISO 11801 l n GG 45 Cat 7 A and RJ 45 Cat 6 A (and 6, 5 e) Preferred Cat 7 A connector Data Centres ISO/IEC 24764 Tera (IEC 61076 -3 -104 ) l l Non RJ 45 compatible Option in ISO 11801 and in ISO 24764 if cable sharing is more important than backwards compatibility 48
Migration Strategy 49
Migration Strategy t If we install Cat 6 A then 40 G migration is “rip and replace” t Need a cost effective alternative strategy. . 50
How does it work? A protruding part on the plug activates the switch in the jack: RJ 45 & GG 45 Twice the bandwidth, half the crosstalk 51
Migration 10 G 40 G GG 45+Cat 7 A fixed cable links 10 G solution 10 G Access layer switch RJ 45 Cat 6 A patchcords PP PP SERVERS 10 G Patch cords Permanent link 52
Migration 10 G 40 G GG 45+Cat 7 A fixed cable links 40 G solution 10 G Access layer switch Simply replace patchcords With GG 45 cords PP PP SERVERS 40 G Patch cords Permanent link 53
Active Equipment t GG 45 also available as 8 pin PCB version n n mass production capability n t joint development with Bel Stewart enables use of GG 45 in active equipment Trials ongoing with several chip vendors t Using Cat 7 A for 10 G could reduce the coding levels required n reduced complexity = lower cost n reduced coding = lower power requirements n reduced power = reduced cooling. . . 54
LANmark-7 A t Enables a common cabling infrastructure running Converged Enhanced Ethernet for LAN, SAN & cluster computing n n 1 G 10 G 40 G over 100 m n t reduced complexity therefore maintenance costs Increased design flexibility to balance load/reduce hotspots Double the bandwidth / half the crosstalk n in short reach mode more cancellers can be turned off sooner n potential for energy cost savings n T variant ALWAYS follows OF version 55
LANmark-7 A Energy Efficient Transport Medium t Superior shielding and signalling offer the opportunity to turn off/reduce transceiver compensation power t Example of potential annual energy and cost savings based upon 300 racks, 20 servers per rack and associated access layer switches and storage Power Saved per Network Port Total Number of Network Ports Total Power Saved Total Annual Cost Savings 5 Year Cost Savings 1 watt 36, 000 315 MWhrs £ 22, 200 £ 111, 000 2 watts 36, 000 630 MWhrs £ 44, 400 £ 222, 000 56
The Fibre Problem 10 G 40 G Connector = LC Connector = MPO OM 3 Low fibre count per link (typically 2 fibres) OM 3/4 High fibre count per link (typically 12 fibres) 57
Summary t Data centre infrastructures need to be scalable to 40 G n t Fibre migration can be achieved using cassette solutions n n t requires careful planning because new copper and fibre interfaces are needed Complexity due to fibre count and port densities Low loss connectors and OM 4 fibres to be used in future proof installations Copper migration can be achieved using GG 45 ‘ 2 in 1’ connector n potential cost savings from implementation of EEE 58
