Data Center Cabling

The new European standard (EN 50600 – X) will be in place by the end of 2015 will be the new European reference for all parties involved in the construction and design of a data center. The standard focuses primarily on the design requirements for different classes DC with a strong emphasis on migration and development. On this page we will highlight the requirements for fixed infrastructure cabling, cross – connect cabinets, equipment row cabinets, cable management and pathway according to the availability of the Data Center.

The European standard EN 50600 X-SERIES

This series of European standards indicate the requirements and recommendations to support the various parties involved in the design, planning, supply, integration, installation, operation and maintenance of facilities and infrastructure within the data center.

The parties are:

  • Facility Managers, ICT, Project Managers, Contractors
  • Consultants, architects, builders, designers installation
  • The equipment suppliers
  • Installers , maintainers

It was developed to meet the European demands in design DC:

  • A standard design DC European was requested with the applicable requirements for European standards
  • The application of a series of standard design DC universally applicable adopting a holistic approach that covers all aspects of the design of current installations including the management of operational information
  • Support the Code of Conduct of the European Commission on energy efficiency of the Data Center
  • Schemes existing designs were driven by design concepts of resilience

The EN 50600-x series covers all the design needs for the entire set of facilities and infrastructure of a data center in separate standards. The chart below shows the structure and the relationships between all the EN 50600-x standards.

Main Benefits

The EN 50600-X was developed by CENELEC (European Committee for Electrotechnical Standardization), nonprofit organization of independent European standardization.

EN 50600-X:

    • It provides definitions and requirements relating to the operation of all facilities and infrastructure
    • Is applicable internationally to owners/managers/operators International
    • It replaces the reference standards with European partners International
    • It replaces the European safety standards

In addition, the EN 50600-x:

    • It offers as standard single DC design an approach enabling energy efficiency which provides the basis for all the concepts of KPIs
    • It provides information on the selection process for the design parameters of the Data Center
    • It provides design principles for designers and owners DC
  • It defines non-profit certification criteria

Main Benefits

The standard EN 50600 is lagging behind other rules concerning the Data Center. However, EN 50600-X offers a lot of benefits for all those involved in the design and construction of data center operational. The main advantages are:

DC Owner / Manager / Operator can use the standard EN 50600 to translate business needs through the assessment of risks in terms of availability of infrastructure compared to the costs, in order to:

  • Locate and select the appropriate requirements of the schematic design to provide the desired availability
  • Apply concepts that are standards-based, business-oriented product / technology agnostic

Consultants for DC, EN 50600-X Series is a standard reference for the evaluation of the design principles for all data center services.

Architects and engineers get a suite of integrated standards for the design of data centers, including design principles.

General concepts

EN 50600-1 describes the general concepts of the standard series and has the following scope:

  • It illustrates the problems to be addressed in a risk analysis of business and operational costs by allowing the application of an appropriate classification of the Data Center
  • It defines the common aspects of the data center, including terminology, parameters and reference models (functional elements and their loading) that address both the size and the complexity of their destination
  • Describe the general aspects of the facilities and infrastructure necessary to support the effective functioning of telecommunications in the data center
  • A specific classification system, based on the key criteria of “availability”, “security” and “energy efficiency” for the expected duration of the data center, for the provision of facilities and effective infrastructure
  • It describes the general design principles for data centers on which the requirements of the EN 50600 series are based including symbols, labels, coding in the drawings, quality assurance and education.

Also, it works as a basis for all other series standard because their infrastructure must be designed according to the global data center by class of availability chosen, derived from EN 50600-1.

EN 50600-2-4: TELECOMMUNICATIONS CABLING INFRASTRUCTURE

Content and structure

The telecommunications wiring within the data center is used to support the following:

  • The Information Technology Data centers and telecommunications networks
  • Monitoring and control of other data center infrastructure
  • Building management and automation

Therefore, EN 50600-2-4 addresses the wide range of telecommunications cabling infrastructure within the data center based on the criteria and classifications for “availability” by EN 50600-1. EN 50600-2-4 specifies requirements and recommendations for the following:

  • Information technology and telecommunications network cabling (eg, SAN and LAN)
  • General wiring information technology to support the operation of the data center
  • Telecommunications cabling to monitor and control the distribution of energy, environmental control and physical security of the data center
  • Other cables building automation
  • Pathways, spaces and enclosures for telecommunications cabling infrastructure

The main objective in the development of EN 50600-2-4, was, in addition to the architecture and requirements classes of availability on migration and development. The growth of IT capacity and application migration to higher speed are very dynamic data center. L ‘cabling infrastructure of a data center must be able to support these dynamics, enabling the rapid extension of the Data Center and providing migration paths for network applications and storage used in DC. EN 50600-2-4 supports the migration and growth by establishing appropriate requirements for architectures and systems cabling pathway.

Cabling Types

Although EN 50600-2-4 covers different types of cabling, it defines no requirement for structured cabling itself. It was created to replace the existing European standard wiring but aims only to those definitions for wiring.

EN 50600-2-4 defines basically 2 types of wiring:

Point-to-point: The direct connection of two pieces of IT equipment via a dedicated cable, rather than a generic cabling system. The method of point-to-point using cables that connect directly to the active equipment.

Fixed Cabling: cabling structured cabling solutions including generic EN 50173 series of closures that have peer-to-peer or hierarchical structure and allowing the installation of interconnections or interconnection in such closures.

Point-to-Point Cabling seems to be the easiest and most effective to provide connections, for several reasons this type of cabling must be used only for connections within the same or two adjacent cabinets, frames or racks. Point-to-point cabling is often not reusable as the Data Center, it can have a long life expectancy limited.

Fixed Cabling 

A better approach for telecommunications in a data center is the use of wires. The equipment can be connected to the active systems during planned downtime by simply reconfiguring the ropes CPL or ZPL. If a change causes a problem, you only need to reconnect the cables in their configuration of pre-modification. The implementation of fixed wiring allows more accurate predictions of the time required to implement changes to the system (and recovery) easier, faster changes that introduce less risk and allow better functioning of the system.
