13 10G Copper vs Fiber: Just the Facts 13
14 10GBASE-T Standard (10G on Twisted Pair Copper) IEEE 802.3an 10GBASE-T 10G Standard 100m CAT6A UTP 100m CAT7 STP 55m or 37m CAT6 UTP 2.5 Gb/s per twisted pair across 500 MHz frequency range Cable is not 100% tested when manufactured (sampling used) Augmented Category 6 (to be 568-B.2 Add10) TIA Cable Standard Optimistically looking at late 2007 for publication Commercial offering now considered proprietary solutions Not TIA-568 and TIA-942 compliant 14
15 FACT: No Transmission Equipment is Available 10GBASE-T capable switches are not commercially available Optimistically, 10GBASE-T capable equipment won t be available from Cisco until sometime in the second half of 2008 The only copper based equipment available today for copper is 10GBASE-CX4 Twin axial Coax cable. Distance limitation is 15 meters 15
16 FACT:10GBASE-T Presents Density and Heat Issues Significant switch and server adapter card power requirements 10G copper requires watts per port 60W allocated per card Reduced switch port density Projected 4-8 ports per 10G copper card Max.100m distance 10G optical switch X2 transceiver: Max 4 watts per port (or 16 ports per card) XFP transceiver: Max 2.5 watts per port (or 36 ports per card) SFP+ transceiver: Max 1.0 watt per port (or 48 ports per card) 10G copper watts per server adapter card 30m service distance 10G optical <9 watts per server adapter card 300m service distance Heat dissipation 16
17 FACT: 10GBASE-T Presents Transmission Issues Transmission Issues Complex digital signal processing (DSP) required for internal noise cancellation Latency Issue 10G optical typical PHY latency in the nanosecond range (10-9 sec.) where 10G copper has PHY latency in milliseconds (10-3 sec.) A one-millisecond advantage in trading applications can be worth $100 million a year to a major brokerage firm, Information Week, April 2007 Sun Microsystems states PHY latency should next exceed 1 microsecond. May start effecting Ethernet over TCP/IP application performance in the foreseeable future Susceptible to external noise such as alien cross-talk and EMI Cannot be corrected with electronics due to random nature No 100G Migration Path Over Required Distances OM3 included in IEEE 100G PAR Minimum 100m distance 17
18 FACT: 10GBASE-T Presents Pathway & Space Issues Larger Cable OD and heavier 108 circuits at 200ft CAT6A, 108 cables, 1000lbs, typical effective diameter F optical cable, 40 lbs, effective diameter Cables vs (1) 96-fiber cable 18
19 FACT: 10GBASE-T Presents Pathway & Space Issues Cannot bundle with lower Category copper cables Alien Cross-Talk Reduced Patch Panel Density Typical 50% reduction Inhibits raised floor cooling efficiency Air flow obstruction Interferes with ventilation system to remove dust and dirt 19
20 FACT: 10GBASE-T Presents Install & Testing Issues 10-20% Contractor Labor Premium Larger, heavier cable 25lb tensile rating, No tight bends Difficult to Terminate, Jacket Removal, Pair Untwisting Larger plugs and jacks Testing More Complex and Time Consuming 500 MHz (expensive new equipment) Alien Cross Talk» 17 minutes to perform a single alien crosstalk measurement. Fiber tests only one parameter - Attenuation 20
21 Emerging Technologies 100G Ethernet IEEE HSSG Approved Motions (November 2006) 100 Gbps At least 100 m on OM3 MMF At least 10 km on SMF Key project dates Study group formed in July 2006 Project authorization anticipated in September 2007 Task force formed in November G standard complete in November

23 100G Circuit Price Comparison Between OM3 and SMF Relative 100G Circuit Price G Circuit Relative Price (point to point architecture) OM3 144F, SDM 10x10 OM3 144F, SDM,cWDM 2x5x10 OS2 12F, cwdm 10x10 OS2 24F, cwdm, 10x Distance (m) 23
24 Emerging Technologies Data Center Predominant Protocols used in Data Center Ethernet used for LAN connectivity FC used to manage applications and data on SANs 24
25 Emerging Technologies InfiniBand Architecture: Server Area Network (HPC) 25
26 Emerging Technologies Why InfiniBand in the Data Center? Application Designed to simplify and speed server-to-server connections and links to other server-related systems, such as remote storage and networking devices Server clusters Facilitate use of low-cost servers Potential single fabric protocol Reliable transmission Virtualization Media types Optical fiber Twinaxial copper cable Consolidate many wires to a single connection 26
27 Emerging Technologies InfiniBand Parallel Optics Source: IB Standard 4X-SDR,DDR or QDR 27

29 Emerging Technologies InfiniBand Parallel Optics 12X-SDR, DDR or QDR Source: IB Standard 29
30 Data Center - Key Take-Aways The time for fiber is now The value proposition for fiber between the distribution switch and the server is compelling Transmission equipment doesn t exist for 10GBASE-T When it arrives, port density much lower than fiber 4 8 ports per blade compared to ports per blade Signal quality susceptible to cross talk System latency is higher than fiber High power requirements results in higher generated heat, contributing to higher cooling needs Installation and testing is more complex and time consuming than fiber installation and testing. Contractors charge a premium for ANEXT testing No migration path to speeds beyond 10G 30
31 Data Center - Key Take-Aways Parallel optics is required for Infiniband, 100Gbe and FC above 16G 12-Fiber array connectivity will future proof your data center for the future Kevin Kettler, Dell Chief Technology Officer, stated in Electronic Engineering Times, June 26, 2006: instead of a wholesale transition to 10G over copper, the networking Industry may well segue into optical fibre. The next speed is 100GigE and copper will not work over required distances at those data rates." 31
