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

The Checklist will help to avoid this

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

Height 2210mm (87 inches)
Width 600mm (23.6 inches)

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 world’s colocation facilities?
8
The Colo Facility Challenges
• Structural
• Electrical System
• Cooling
• Pathways
• Network Architecture

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

White Space slab to slab and ceiling heights

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

Access ceiling
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
plenum return
23
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
