Market Situation Standards Update and Topology 40G and 100G Ethernet - Impact on IT Cabling Migration Options with Fiber System
Market situation
DC evolution in brief Data Centre as total cost to the business with no contribution towards the revenue stream Data Centre as integrated service provider delivering value and wanting to be relevant to the business Data Centre as a strategic business tool that enables business transformation and adds value to P&L
The new role of modern Data Centers Evolving from a simple service provider to a business partner A strategic business tool for revenue generation Highly scalable, highly dynamic and highly resilient Virtualised for private and public cloud technologies Greener and Leaner IDC report Dec 2010
Market situation More different data centre types Some customer groups have specific demands or a combination of everything It s obvious, that demands and requirements more fragmented
Market situation Systems are being chosen by application and environment Currently Cat.6 UTP and OM3 fibre systems are most common Cat. 6A and OM3/4 are seen in most recent projects Cat.7A and STP in principle is gaining (EMC and lifetime)
Market situation Drivers in the data centre market New applications Virtualization Consolidation Expansion Storage Cloud services

Network Convergence Data Center Network Convergence: Unified network transport technology to provide a single seamless fabric for data transport between server, network and storage elements Network Convergence Benefits: A single, common network to manage Only one type of network adapter (CNA) required instead of both Ethernet NICs and Fibre Channel HBAs Network Convergence Challenges: Requires 10G fiber connections Increases backbone bandwidth req s

DC Cabling Design Main Design Topology Top of Rack (TOR) Virtual Top of rack (V-TOR) In-Row Distribution End of Row (EOR) Mid of Row (MOR) Design & Architecture Agnostic Help To Reduce Complexity
DC Cabling Design Top of Rack
DC Cabling Design Top of Rack Fiber to each rack future proof PRO No dense copper cabling between racks No dense copper patching fields Potentially lower cabling costs Copper stays within rack 1G or 10G servers today Switch upgrades/issues only affect rack Easy per rack upgrading of server access technology More switches to manage CON Higher AGG port count Higher STP logical ports in AGG More server-to-server traffic in AGG Potentially higher switch costs
DC Cabling Design Top of Rack Pros Efficient use of network cabling Efficient use of floor space Cons Inefficient use of LAN/SAN switch ports due to oversubscriptions Difficult to manage equipment maintenance and upgrade in large deployments Potential overheating of LAN/SAN switch gear in server racks
DC Cabling Design Point of Distribution (In-row)
DC Cabling Design End of Row Less switches to manage PRO Lower AGG port count Lower STP logical ports in AGG Potentially lower switch costs Less server-to-server traffic in AGG Better HA, longer life modular switch platform for server access Dense in-row copper cabling CON Dense RJ45 patch fields Racks dedicated to network, patching Less server density per row 1G today, 10G tomorrow Network upgrades/issues affect entire row More difficult per row upgrading of server access technology
DC Cabling Design Point of Distribution (In-row) Pros Very scalable, repeatable design Excellent balance of cable cost and switch port utilization Repeatable and predictable Keeps cable bundles manageable Allows implementation of network applications with limited cable distances Recommended cable architecture of TIA-942 Data Center Standards Lower cabling cost vs. Centralized Direct Connect Cons Not appropriate or economical for Small data center Not suitable for deploying Top of Rack equipments
DC Cabling Design Point of Distribution (In-row) Most widely deployed topology in Enterprise data centers Typical End of Row or Zone/Pod layout Current Best Practices Hot aisle/cold aisle Full cross connect Intelligent patching
40/100 Gb/s Systems Impact on the IT Cabling
40/100 Gb/s Systems Roadmap to 100 GigaBit Ethernet http://www.ieee802.org/3/ba/public/index.html
IEEE latest draft Table 86 2 40GBASE SR4 and 100GBASE SR10
IEEE latest draft Table 86 13 40GBASE SR4 and 100GBASE SR10
40/100 Gb/s Systems OM3 or OM4 Multimode Fiber 40GBASE-SR4 4 Tx and 4 Rx parallel channels using 4 + 4 MM parallel fibers with MT technology No single fiber solution
40/100 Gb/s Systems OM3 or OM4 Multimode Fiber 100GBASE-SR10 10 Tx and 10 Rx parallel channels Using 10 + 10 MM parallel fibers with MT technology No single fiber solution 3 Wire map options using 12 or 24 fiber MPO connector
40/100 Gb/s Systems OM3 or OM4 Multimode Fiber 3 Options for 100G 1 MPO (preferred) 2 MPO top and bottom 2 MPO side by side All use the 10 center fibers Rx Tx Rx Tx Tx Rx NOTE: all views are looking into transceiver
Singlemode 40/100 Gb/s Systems OM3 or OM4 Multimode Fiber Alternative Singlemode as length up to 40km possible Pricing for Actives is still high Case by case decision
40/100 Gb/s Systems Migration options
40/100 Gb/s Systems Migration Options
40/100 Gb/s Systems Migration Options Option A Upgrade to 40/100 Gb/s Solution for 40 or 100G using 12 fiber MPO at the equipment Solution for 100G using 24 fiber MPO at the equipment
40/100 Gb/s Systems Migration Options Option B Upgrade to 40/100 Gb/s
40/100 Gb/s Systems Connector Requirements IEEE asked for: Connector loss: 1.5dB for OM3 and 1.0dB for OM4 Return Loss at the transceiver: 12 db min. In general: For VCSEL application you need high optical requirements and extreme stable End Face geometry
40/100 Gb/s Systems This result in some new challenges: Connectivity is essential to achieve channel performance Wrong fibre or connectivity result in design limitations OM3 or OM4 is important above 100m A proper system design is needed for good ROI and the typical needs such as scalability and upgradeability
Conclusion
Aligned DC solutions Agility Availability - Efficiency 1 GbE Copper & Fibre Solutions 10 GbE Copper & Fibre Solutions 10 GbE 40 GbE 100 GbE Fibre MPO based Solutions Adaptive Technologies To Meet The Changes In Business Requirements
Conclusions Data Centre are being more structured according to standards Agility, Availability, scalability and efficiency are the basics around the world After 10 Gb/s data centres will be the first place for new technologies A solution needs a holistic view and approach to serve data centre needs
