Introduction to Data Centre Design

1. Introduction toData Centre Design

2. The Purpose Routing of cables Protection of cables Adherence to Standards

3. Data Installation Standards BS 6701 Telecommunications Equipment and cabling EN 50173, ISO 11801, ANSI/TIA/EIA-568-B Generic IT Cabling For Customers Premises EN 50174 IT Cabling Installation EN 50310 Bonding & Earthing In Buildings With IT equipment ISO/IEC TR 14763-2 Information technology � Implementation and operation of customer premises � part 2: Planning and installation

4. Installation � EN50174 Separation of services Dependent upon type of cable used and type of cable management Reduction in Electro Magnetic Interference By separation Crossing power at right angles

5. Cable Separation - �OLD� EN50174-2

7. Electrical Installation Standards Electrical Installation Standards deal with safety issues BS 7671 (IEE Wiring Regulations), Section 528 concerns separation of different electrical services Telecommunication circuits should be segregated in accordance with BS 6701

8. BS 6701 � Minimizing The Risk Of Dangerous Voltages

9. TIA 942 cable separation

10. Fill Rules

12. Cat 6A screened 30% smaller than unscreened Cat6A

13. Distribution Choices Ladder rack Solid bottom cable tray Perforated or trough cable tray Spine cable tray (centre rail construction) Wire tray (welded wire construction) Mesh cable tray (wire or plastic mesh) Wireway with fully gasketed cover Cable runway, i.e. no side panels, cable is tie wrapped to base tray Metal/PVC-u Trunking

14. Patchcords must be organised within the racks

15. Use vertical and horizontal cable managers

16. A vertical cable manager shall be installed between each pair of racks and at both ends of every row of racks. The vertical cable managers shall be not less than 83 mm in width. Where a row of two or more racks is installed, consider mounting 250mm wide vertical cable managers between racks, and 150 mm wide vertical cable managers at both ends of the row. The cable managers should extend from the floor to the top of the racks

17. Use vertical and horizontal cable managers

18. Organise cables within the rack

19. Organise cable around datacentre and into racks

21. Organise cables in vertical risers, including fire stopping

22. British Building regulations: 2000 Part B, Fire-stopping 11.12 In addition to any other provisions in this document for fire-stopping: a. joints between fire separating elements should be fire-stopped; and b. all openings for pipes, ducts, conduits or cables to pass through any part of a fire separating element should be: i. kept as few in number as possible, and ii. kept as small as practicable, and iii. fire-stopped (which in the case of a pipe or duct, should allow thermal movement). 11.13 To prevent displacement, materials used for fire-stopping should be reinforced with (or supported by) materials of limited combustibility in the following circumstances: a. in all cases where the unsupported span is greater than 100mm; and b. in any other case where non-rigid materials are used (unless they have been shown to be satisfactory by test).

25. Earth everything!

26. �and label it!

27. Putting It Together Pick right cable containment for the job Earth/bond/ground correctly Label pathways Protect bend radii of data and fibre cables Maintain separation from power cables Keep integrity of fire barriers
