Data Center Cabling Standards

Data Center Standards

• TIA 942: Telecommunications Infrastructure Standard, April 2005

– Substantial, Available, American

• EN 50173-5: Information technology – Data Centers

– Smaller scope, European perspective

• ISO/IEC Draft 24764: Information technology

– Global Generic Cabling for Data Centers

Hierarchical Structure of Data Centers

Tiers• The Uptime institute defined 4 levels of reliability for Data

Centers

Not much time

for re-cabling

Data Center Cable Types

• Fiber media types:

– Singlemode fiber– Multimode fiber – TIA: recommendation OM3 (XG) | ISO min. OM3 (XG)

• Copper media types:

– TIA: min. Cat. 6 | ISO: minimum Class E A !!!!!!!

Premium Passive Solutions for Data Center

• DC cabling requirements aredifferent from the ones in Office Networks

• Static vs. Dynamic

– Easy deployment (weekend work/testing)– High performance– Structured scalability– Fast & easy MAC‘s (operational cost)– Functional Security (less human errors)– High density (cost of space)– Effective cable management– Availability (less planning, less downtime)– Cooling/airflow support

Data Center Applications & Technologies

Today & Tomorrow

GBE/10GBE

• GigaBit Ethernet

– OM1/OM2/OM3 for fiber (1000Base-SX/LX)– Cat.5e for copper (1000Base-T)

• 10GigaBit Ethernet

– OM3 recommended for fiber (10GBase-SR)– Cat.6A/Cat.7/Cat.7A for copper (10GBase-T)

• Utilisation of 12 ribbon fiber & MPO connectors an important factor for economic feasibility of 100G MMF

• Pre-terminated OM3 ribbon fiber will be cost-effective

Premium Data Center Cabling

Solutions

The Premium

• Modern Data Center Cabling Systems have to meet or exceed:

– all Data Center Cabling Standard Definitions

– all Data Center specific Cabling Requirements

– all Technology & Application Requirements (today & tomorrow)

Recall: DC Premium Cabling Requirements

– Easy deployment (weekend work/testing)

– High performance– Structured scalability– Fast & easy MAC‘s– Functional Security (less human

errors)– High density– Effective cable management– Availability (less planning,

less downtime)– Cooling support

Pre-terminated Plug & Play

Modular Cabling Solutionfor Copper & Fiber

MRJ21 MPO 1€

High Density Pre-terminated Solutions

• Pre-terminated MRJ21 Copper System

• High Density with 6 GBE Channels per cable

• Pre-terminated MPO Fiber System

• High Density with 12 or 72 fibers per cable

ISO/IEC 24764 Data Center Standard

Backbone

Horizontal

• Combines high density and ease of maintenance with energy saving:

• Doubles GBE switch capacity compared to RJ45 interface

• Utilize existing chassis

• Flexibility

• Rapid installation / change-out• Fewer cables to manage on the switch

MRJ21: The End-to-End System approach

Network Vendors with MRJ21 Equipment

• Alcatel TiMetra• Barco Xenia• EIT• EntriSphere • Foundry Networks• Force10 Networks • Fujitsu • IBM • Lucent • Motorola • NMS Communications

• Proworks

• Shanghai Electronics• Stratex Networks• Tellabs / Vivace

Force10 E1200

Up to 1260 GBE ports / chassis

High-density Pre-terminated Solutions

• Common Systems features:

– High-density and/or modular connectivity– The simplicity of a “Plug&Go” installation– Factory tested– Less Installation time in avg. 5x faster

than traditional termination/panel– Space saving in average 30%

(pathways & spaces)– Support of cooling concepts– Easy Scalability

Recall: DC Premium Cabling Requirements

– Easy deployment(weekend work/testing)

– High performance– Structured scalability– Fast & easy MAC‘s– Functional Security

(less human errors)– High density– Effective cable management– Availability

(less planning, less downtime)– Cooling support

Zero U Cable Management

Why Cable Management ?

• Does this look familiar?

– Unmanaged and unstructured connections

– No documentation– 30-40% abandoned patch cords

after 1 year of operation– Dead ports in switches and cable

runs 30-40% unused capacity– MAC time > 1h per port– Adds up to 150% of operational

cost– Adds up to 200% of floorspace

needed – Heat sinks creation (blocking of

air flow)

Zero U Cable Management Technology

• Zero U Corner Brackets combined with AngledPatch Panels

– Eliminates the need for horizontal cable managers– Uses unused valuable cabinet space– Effectively increase of cabinet density– Available for Copper & Fiber
