I. Introduction

This document is intended to capture data that is required by the Project DesignDepartment to create a cabling design study for Data Centre projects. The work flowschematic is used to cover all aspects affecting cabling and simplify the decision makingprocess.

Mandatory information listed below is marked in parenthesis (Man).

Supplementary information which would enable a better understanding of customerrequirements and assist in providing a value added design proposal is marked (Sup).

II. Standards

The Data Centre cabling shall comply with

ISO/IEC 24764:2010: Information technology - Generic cabling systems for Data Centresor

EN50173-5:2011: Information technology - Generic cabling systems - Part 5: Data centres

Those standards are making reference to the general building cabling standards

ISO/IEC 11801:2011or

EN 50173-1:2011 + EN50173-2:2011 (Design)

EN50174-1:2011 + EN50174-2:2011 + EN50174-2-3:2003 (Installation)

The cabling architecture in a Data Centre is divided into different subsystems as it is forthe cabling architecture of a building but the names of those sub-parts (as defined in theDC standards) are different.

In order to select the applicable cabling standard and infrastructure design, the followingshould be taken into account

Current and future bandwidth requirements

LAN & SAN convergence

Scalability and migration to higher speeds

Resiliency and redundancy

Flexibility for equipment placement, reconfiguration due to equipment failure andany-to-any connectivity

Expansion; new equipment and/or cabling additions

Intelligent Cabling Management System (LANsense) as recommended byEN50174-1

Data Centre Infrastructure Standards EN 50600 Series (In development)

This standard specifies general concepts for data centre facilities and infrastructures. It

defines the common aspects of data centres, specifies a classification system, basedupon the key criteria of "availability", "security" and "energy-efficiency" over the plannedlifetime of the data centre, for the provision of effective facilities and infrastructure anddescribes the general design principles for data centres.

III. Distribution

A. Dis tribut ion scheme

In order to understand the needs of the Data Centre it is imperative to know how all thepieces will interconnect with each other. Based on this information the matrix of theinterconnections can be made.

The complexity of this matrix will depend on the size and resilience of the network.

1. End of server row switching (Man)

2. Top of server rack switching (Man)

3. Centralised server row switching (Man)

4. Dual end of row switching (Man)

5. Computer Edge Switching (Man)

6. Edge to Edge Corporate switching (Man)

7. Edge to Edge Collocation switching (Man)

B. Availability (Sup) According to EN 50600-1

The acceptable level of availability of the DC is to be determined.

Downtime cost analysis (EN 31010) Risk of loss of services analysis (EN 31010) Implement redundancy to reduce the high and critical risks

Classes of availability for telecommunication cabling

Class 1: Single path using direct connectiono Shall be the exception Limited scalabilityo Not recommended

Class 2: Single path using fixed infrastructureo Flexible and scalable designo Central Patching / Cross-connect requiredo Minimum recommended Class

Class 3: Multi-path using fixed infrastructureo Flexible and scalable designo Shall be future-proof (Performance > fasted application)o Pre-terminated cabling recommended (Security & availability)

Class 4: Multi-path using fixed infrastructure with diverse pathways

o Flexible and scalable designo Shall be future-proof (Performance > fasted application)o Pre-terminated cabling recommended (Security & availability)o Redundant cabling diversely routed

Will the cabling and the network of your Data centre offer redundancy to reduce the risk ofcostly and critical downtime?

If so, please indicate the redundant links onto the layout

Example of dual pathways layout (Also see next page)

C. Data centre layout

1. Data centre rack layout (Man)

The following diagram is a typical representation of a data centre rack layout showingserver, network, storage and cabling racks, which will vary from customer to customer. Inorder to provide an assessment for the design, bill of materials and costs, an indication ofthe position and number of racks for each type is required. The detail of this information islisted further on in points B, C, D & E.

IV. Components

A. Copper cabling specification

Server, switch and storage virtualisation are the main drivers for higher speeds. ModernData Centres need to support a minimum of 10G Ethernet now with the potential tosupport 40G within the next 3 5 years. LANmark 6A therefore is the minimum coppercabling spec that should be considered. High availability server farms will require futureproofing beyond 10G and therefore LANmark 7A should also be considered.

V. Added value

According to the latest EN-50174 standard it is recommended to foresee an automated

system to control Moves, Adds and Changes (MAC) in your data centre. LANsense issuch a system which provides real time mapping of the cabling infrastructure. Otherfeatures are also available which includes EMAC (Environmental Monitoring & AccessControl). In order to implement LANsense additional information is required.

A. LANsense

LANsense is Nexanss Intelligent Infrastructure Management (IIM) solution. It is aninternet enabled hardware and software package which can automatically discover andmonitor network connectivity in real-time, to ensure network connections are secure andthat connectivity documentation is always 100% accurate. LANsense is vendorindependent and can be retro-fitted to existing systems.

Benefits:

Increased Security Cost effective change control and management Reduced downtime Asset Management Remote site monitoring the ability to integrate EMAC

1. Area to monitor

We need to know all the patching zones that need to be configured with LANsense, this

can be done by marking them in the matrix list. Those areas can mainly include theDistribution area (patching frame) and the end of server rows.Note: If a top of server rack switching scheme is selected the monitoring of the server toswitch connections is not useful because the LANsense system will automatically detect ifswitch ports are connected to each port of the server.

2. Hardware required

Analysers the LANsense analysers are permanently connected to every (copper andfibre) intelligent patch panels to detect the port connectivity and feed the output to thesoftware database.

Patch Panels and Cords LANsense intelligent patch panels and cords incorporatesensor circuits (based on 9thwire technology) to detect the insertion or removal of cords.

3. Software required

LANsense Software The LANsense software is a control and reporting tool.

Two platforms of software are available:

LANsense Enterprise Edition: a fully featured package which can becustomised according to the individual client requirements

LANsense Data Centre Edition: a fully featured, customised package withspecific tools designed to meet the operational needs of Data Centre managers


23/29



B. EMAC

EMAC is a set of tools managed by the ICMS of the cabling, for example Nexans

LANsense Enterprise software, or used as a Stand-alone system. In this case, the

management is performed through the built in web management interface.

This set of tools shall be used for the following:

Monitoring and control of power in server and switch racks

Measurement of temperature and humidity inside server and switch

racks

Detection of open and closed rack doors

Controlling rack door access

Controlling door access to computer roomsRack door keypads to enhance security (Optional)

Retro-fit solution for existing dumb power strips.

Water detection
