Critical Elements in a DataCentre

  • Tiering of Data Centre
  • IT Area Versus Non-IT area
  • Ceiling Height and Raised Floor System
  • Power Design (Supply + cabling)
  • HVAC units (Temperature and Humidity)
  • Fire Detection and Suppression
  • Environmental Monitoring System
  • Structural Loading
  • Physical Security
  • Structured Cabling
  • Network Considerations

Tiering of Data Centre

  • Defining the Tiers.

Tier I Tier I is composed of a single path for power and cooling distribution, without redundant components, providing 99.671% availability. Tier II Tier II is composed of a single path for power and cooling distribution, with redundant components, providing 99.741% availability. Tier III Tier III is composed of multiple active power and cooling distribution paths, but only

  • ne path active, has redundant components, and is concurrently maintainable,

providing 99.982% availability. Tier IV Tier IV is composed of multiple active power and cooling distribution paths, has redundant components, and is fault tolerant, providing 99.995% availability

NUS DC Live Migration – the Art and Challenges

slide-21
SLIDE 21

Key Considerations and Difficulties Encountered

  • The datacentre must have minimal downtime as it is running live.
  • Renovated DC must be able to cater for DC operation till year 2010.
  • Deciding DC tier level.
  • Maximising IT Area.
  • Identifying possible/planned hot spot/area.
  • Non-standard air flow racks/equipments.
  • Inter-racks dependencies.
  • Control/minimising dust in operating IT area during the renovation.
  • Racks with weight overloading floor structural design.
  • Air flow issues within a rack.
  • Standardising racks design.
  • Linkage of M&E vendors and IT vendors during renovation and IT migration

in this live DC.

OLD DC OLD DC

  • Single incoming power source

(electrical to IT)

  • Standalone UPSes; not all

equipment on UPS

  • Equipments mostly on single UPS

supply

  • Insufficient cooling with no humidity

control

  • Generator does not meet existing IT

load requirement

  • No environmental monitoring system
  • Building smoke detectors and

I nergen gas system at selected areas

  • Un-structured cablings

DATA CENTRE @ NUS

slide-23
SLIDE 23

New DC

  • Two different incoming power source to

DC (electrical for IT)

  • Centralized 2N UPS with individual

isolation transformer supplying power to all IT equipments in DC

  • Dual power source for all IT racks
  • 400mm Raised Floor System
  • Fire detection and protection systems -

FM200 and building smoke detectors

  • Structured Cabling
  • Hot & Cold aisles with ducted return
  • Fire rated perimeters
  • Stand alone earthing system
  • CCTV Monitoring
  • Contactless Door Access System
  • Dedicated N+ 1 Crac units with

humidity control, backup by a dedicated

generator

  • New generator for IT electrical supply
  • EMS (temperature, humidity, water

detection, PDU incoming and outgoing, crac units, FM200, etc)

I nteresting Facts...

  • Renovation Duration

: 1 Year

  • DC NFA

: 720 sqm

  • 60% attained IT Area
