    DCD London November 2016 - Data Center Project Engineering Workshop

  • Checklist Concept

    To be useful world wide

    Consider only the white space

    Simple and easy to use so that the older style Colo facilities can easily adopt Open Racks

    First step - create a Minimum Viable Product checklist for one average Open Rack variant

    2

  • The Checklist will help to avoid this

    3

  • Open Rack Standard V2.0

    4

    Key Rack Features Include : -

    Base rack loading to 500Kg

    Heavy rack loading to 1400Kg

    2 Power zones with optional kit to

    convert to a single zone

    Dimensions

    OpenU Height 48mm (1.89 inches)

    Height 2210mm (87 inches)

    Width 600mm (23.6 inches)

    Depth1067mm (42 inches) Front Isometric View Rear Isometric View

  • Open Rack Variant Considerations

    Is a typical facility requirement for an Open Rack 12.5kW and

    800Kg?

    Could that typical Open Rack Variant be accommodated by 80% of

    the worlds colocation facilities?

  • Ramps

    12

    600 mm 12 x 600 = 7,200 mm

    1,800 mm minimum width

    Landings both ends of minimum 1,800 mm square for manoeuvring equipment

    No steeper than a 1 in 12 incline

  • What are the Rack Delivery & Placement

    Considerations?

    Can a crated Open Rack be delivered and manoeuvred into the Data

    Centre store room/ goods in using a fork lift via the loading dock

    Is there sufficient clearance at access doors and in corridors between

    the loading dock and white space

    Is there an adequately sized turning landing at the top of any ramp

    13

  • Floor

    14

    Raised/ Access

    Solid/ Slab

  • What are the Floor Considerations?

    Solid or raised access floor

    Maximum rolling load that can be accommodated between the

    loading dock and the white space

    Maximum static load that the white space can support

    Notes :

    1) Minimums of 3.1 m allows for a one metre minimum clearance above a 2.1 m tall rack.

    Clearances

    900 mm to

    450 mm

  • What are the Clearance Considerations?

    Height and width of the access door at the loading dock

    Height and width of the access door into the white space

  • What are the Electrical Considerations?

    Spare ways in electrical switch gear/ distribution board / PDU fed by

    3 phase non UPS supplies

    3 phase busbars within the whitespace with sufficient power capacity

  • What are the Cooling Considerations?

    Can the white space be adapted to allow for a contained hot aisle

    Is there sufficient clearance above the rack to install a ceiling air

  • Pathways

    24

  • OCP server cabling interfaces at the front

    25

    LAN on front

    Thanks to John Laban for graphics

  • What are the Pathway Considerations?

    Can power and network connections be moved from the rear to the

    front of the rack

    Can network and power connections be routed from the access floor

    to the top of the rack

    26

  • Lighting

    27

  • What are the Lighting Considerations?

    Are light fixtures positioned at a minimum of 2.6 m (8.5 ft) above

    finished floor (AFF) and positioned close to the rack

    Is there a minimum of 500 Lux measured at the points of cable

    termination and connectivity and 1.0 m (3.28 ft) AFF measured in the

    middle of all aisles between cabinets

    Is there 200 Lux available horizontally sideways and both at all points

    in the white space

    Should we consider light colour Open Racks

  • What are the Network Considerations?

    What are the maximum transmission speeds supported by the

    existing copper structured cabling e.g. 10Gb

    What are the maximum transmission speeds supported by the

    existing fibre structured cabling e.g. 10/40/100 Gb

    Link distances between Spine to Leaf and Leaf to equipment
