A method for a direct mapping of FC frames over Ethernet–Seamlessly connects to FC networks Extends FC across the datacenterover the Ethernet

• FCoE appears as FC to the host and thenetwork

• Preserves current FC infrastructureand management

• FC frame is unchanged–Can operate over standard switches(with jumbo frames)–Priority Flow Control guarantees no-drops

• Mimics FC credit-buffer system, avoids TCP–Does not require expensive off-loads

Building hardware is migrating from proprietary independent networks andconnecting directly to the IT network

This can present enormous savings by replacing many networks with oneVisible today in IP security. Recent forecasts suggest that by 2020 this will be themost common way of connecting and integrating all building systemsAs buildings focus on efficiency we will see more energy monitoring and controlconnect to the network, for example plug load control

It’s the Why!

/Nombre del conferencista // Conferencia

With the right planning, the defining elements of capacity,density, efficiency and scalability can be aligned throughthe infrastructure.

One basic best practice: adopt the rackas the basic building block for datacenter density.

7 Elements Critical to Your Network

/Nombre del conferencista // Conferencia

• Density• Network Performance• Flexibility• Protection• Scalability• Energy Efficiency• Airflow Management

Support High Density

/Nombre del conferencista // Conferencia

• Optimize network real estate• Allow for easier MACs• Support for up to 1340

network ports• Deeper management

channels• Adjustable mounting rails

Copper Solutions

/Nombre del conferencista // Conferencia

• Optimize the spaceused on the rack-cabinet by the coppercabling.– Angle panels (remove

horizontal managers)– Increase port count per

RU– Easy deployment– Easy MAC’s

Fiber Solution

/Nombre del conferencista // Conferencia

• Optimize the spaceused on the rack-cabinet by the fibercabling.– Use of trunk cabling– MPO/MPT Solutions– Reduced diameter

cords

Whats a Trunk cabling

/Nombre del conferencista // Conferencia

• Is a preconectorized cable withdiferent designs.

• In Data Center– Microdistribution Loose Tube– Single Loose Tube Indoor / Outdoor

• In the LAN– Tight Buffer Distribution– Tight Buffer Indoor/Outdoor Sunlight

Resistant

• 12, 24, 48, 72 strands• Some 96 and above• OM4, OM3 and OS2• MTP-MTP, MTP-LC, LC-LC, SC, etc

Microdistribution Loose Tube Trunks

/Nombre del conferencista // Conferencia

• Loose fiber premises cabledesign for MTP/MPO array cableassembly

• 3 mm loose fiber with 12 – 250micron fibers

• 12 fiber subunits for 24, 48 and72

• Targeted for MTP/MPO pre-termcable assemblies for DataCenters

• Riser and Plenum• OM4, OM3, OS2• No bend prefered bend radius

Especificación de la TIA para Categoría 8

/Nombre del conferencista // Conferencia

• El grupo de trabajo TIA 42.7 ya ha definido algunos de losparámetros básicos para la categoría 8 pero hay mucho trabajo pordelante que hacer en el estándar. Las especificaciones deCategoría 8 se listaran en el Addendum 1 de la TIA-568-C.2 (a serpublicada como ANSI/TIA-568-C.2-1).

• Según versión draft 0.9, en canal de Categoría 8 es un modelo dedos conectores con una distancia máxima de enlace permanentede 24 metros (79 pies). Como muestra la figura.
