4 Market data and forecasts Allan Nielsen

5 Bandwidth Supply & Demand 40G Servers Gigabit Ethernet Bit Rate (Mbit/s) Core Networking Doubling ~18 months 40 Gigabit Ethernet 10 Gigabit Ethernet Gigabit Ethernet 100 Server I/O Doubling ~24 months

6 CFI IEEE Std BASE-T Roadmap 10BASE-T 100BASE-T 1000BASE-T 10GBASE-T 100GBASE-T Server I/O Doubling ~24 months were these projects too early? CFI 40GBASE-T

7 x.86 Servers by Ethernet Port Speed 12 Based on IDC 2010 server forecast and hays_01_0407 ratios of Ethernet port speed 40G Servers millions server units 100M 1G 10G 40G 100G

8 Server-to-Switch Data Centre Links based 30m Reach for 40GBE & 7m Reach for 100GBE Total Server-to-Switch Links (millions) Based on Flatman contribution to Aug 2009 Penn State Workshop: The Market Opportunity for Higher Speed Ethernet over Copper (updated with IDC 2010 Server Forecast) 100GBE 7-100m Fibre 40GBE m Fibre 40GBE 7-30m Copper 100GBE 0-7m Copper 40GBE 0-7m Copper 10GBE mCopper 10GBE 0-15m Copper 1GBE 0-100m Copper

12 Market Drivers 2015 Forecast of Data Center Speeds and Storage

13 Data Center Speeds Global traffic Source: CISCO Visual Networking Index, Global IP Traffic Forecast 2010

14 Data Center Speeds So what is a PetaBit: Mega = Bit Giga = Bit Tera = Bit Peta = Bit Exa = Bit Zetta = Bit Yotta = Bit One Byte = 8 bit

15 Business share of global traffic Source: CISCO Visual Networking Index, Global IP Traffic Forecast 2010

16 Data Center Speeds Idle / Active profiles Average Busy-hour BW & Average Consumed BW tend to be used quite extensively for Traffic Engineering calculations (determining how much Bandwidth Capacity is required to satisfy a given Service Group (pool) of subscribers Source: ARRIS

17 Data Center Speeds - Forecast Segments Servers: 10G 40G internet 40G 200G Storage 2 VServers Users: 40G 100G internet 100G 1.000G Storage 1G internet 1G 10G Storage Expected growth rates: Server to internet 40% per year Server to storage 50% per year

18 Data Center Storage More storage data is created every two years than all previous years combined Virtualization causes the need for networked storage of all varieties (SAN and NAS) New applications and devices are driving more data access and higher bandwidths 20% of storage is touched by Clouds, 10% is stored in Clouds 2015 Global Storage Forecast Source: IDC's Digital Universe Study, sponsored by EMC, June 2011

19 Global iphone sales Total of iphones sold globally since its introduction Each iphone are offered a 5GByte storage in icloud

20 Storage need for icloud With sold iphones being offered a free 5GB Cloud, Apple needs to establish a storage of at least: X 5 GB = GB = 1 ExaByte Storage This is ONLY for one application for one product from one manufacturer of smart phones.

21 Data transfer times in seconds Size of Data Latency of Latency of Latency of Latency of Latency of Latency of to 1GbE 10GbE 40GbE 100GbE 400GbE 1TbE Exchange 1 Gigabyte GB GB Petabyte PB PB ExaByte

22 icloud transfer times 1 ExaByte By 1G Ethernet = 1 X Seconds = = ~93 Days By 10G Ethernet = 1 X Seconds = = ~9,3 Days By 40G Ethernet = 1 X Seconds = = ~56 Hours By 100G Ethernet = 1 X Seconds = = ~22 Hours By 1T Ethernet = 1 X Seconds = = ~2,2 Hours Needless to say NAS and SAN s needs higher speeds Mirroring of storage more than doubles the need

24 Standards progress Allan Nielsen

25 IEEE A Call For Interest (CFI) planning group have had several meetings, to prepare a CFI for 40GBASE-T. Target date for CFI is July 2012 Supported by uptake in shipments of 10G BASE-T cards Supported by arrival of 10G LAN on Motherboard (LOM) Supported by Switching manufacturers Supported by Cabling manufacturers Technical feasibility checked Economical feasibility checked

26 ISO/IEC JTC1 SC25 Initiative for creating the next generation of cabling: 1st meeting held in Madrid, February 2012: Two proposals have been made for Next generation cabling Category 6B RJ45 connectors and F/UTP cable MHz or MHz maximum frequency 50 metre Channel 2 Connector Channel Shielded Only (Alien Crosstalk and Coupling Attenuation) Category 7B Cat 7A connectors and S/FTP cable MHz maximum frequency As above but with improved performance on NEXT, FEXT.

27 CENELEC TC215 WG1 CENELEC have decided to harmonize with ISO/IEC 11801, when the international group have finalized their work.

28 ANSI TIA/EIA TR.42 TR.42 decided at their meeting held in West Palm Beach, FL in January 2012, that they would develop a next generation cabling under TIA568C.2: Category 8 Connectors and F/UTP cable 40 metre Permanent Link 50 metre Channel Maximum frequency MHz Maximum 2 connectors channel Improved performance on TCL and ELTCL.
