• 2 Stages
• TCDD
• TCCF

• 4 Stages
• Design Certification (Optional)
• Facility Certification (Y0)
• Surveillance Audits (Y1 &Y2)
• Re-certification (Y3)
• Looks at 4 Areas: TEAM
• Other Standards
• BICSI-002
• EN 50600
• ISO/IEC TS 22237

Standards

• Commissioning
• Individual Systems
• Granular Level
• Full Load Testing
• Integrated Systems Testing
• Check Regular Operations
• Check Failure Scenarios
• Run to Fail!
• Vendor Responsibility
• Develop EOPs based on Run to Fail
• Thorough SOP, MOP, and EOP should be maintained
• Reduce Human Error
• Use Check Lists
• Standard Operations
• Detailed Process
• Frequency
• Log Sheets
• Online Database / Tracking
• Maintenance Operations
• Operations Staff Should Witness
• Same requirements as SOPs
• Vendors Should not deviate from the process
• Emergency Operations
• To be defined with Risks and Updated
• Should be drilled frequently!

Thank You for your Time and Attention

Building Readiness for Tier 3+

Mechanical Systems

• Ensure that there are no SPOF in your Mechanical Systems
• Consider Space for Heat Exchange
• Fuel Systems
• Redundant Bulk Storage
• Redundant Piping and Pump Systems
• Control Redundancy and Bypass Capability of Automated Systems
• Individual Day Tanks

Electrical Systems

• Power Supply
• Uptime
• Continuous Run Generator
• TIA-942
• Dual Utility with Standby Generator
• OR Continuous Run Generator
• N+1 or 2N
• Bus Couplers
• 2 Tie Breakers
• Eliminate any SPOF
• Earthing
• Telco Earth
• TIA-607C: Generic Telecommunications Bonding and Grounding (Earthing) for Customer Premises

Telecom and Pathways

• Separate Distribution Paths - Must
• Separate Entrance Rooms
• Incoming Path and Room Separation - 20M
• Must have for Tier 3+, good to have for MTUs
• Provision in advance for Tenant Services
• Avoid work in live shafts as much as possible

Reliability

Engineering

Bigger and Fewer!

Other Considerations

• Space for Panels/Breakers
• Cabling
• Further Points of Weakness
• Number of Breakers
• Number of Terminations

MTBF 43,800 Hours (5 Years)

Then Why!?

• Modular Expandability
• Pay as you Grow
• Smaller Failure Domains
• Cheaper to add +1 Redundancy
• Transport and Placement
• Lifting
• Doors
• Floor Loading
• Foot Print
• Serviceability

MTBF 43,800 Hours (5 Years)

System MTBF 30,971.3 Hours (3.54 Years) - 534.5 Hours Less

MTBF 43,800 Hours (5 Years)

Electrical Systems

MTBF 43,800 Hours (5 Years)

System MTBF 25,287.9

Hours (2.89 Years) - 771.3 Hours Less

MTBF 43,800 Hours (5 Years)

Mechanical Systems

Start Thinking in MegaWatts

• Newer Data Center Facilities should be considered in the MegaWatts Range instead of the 100's of kiloWatts
• The last 3 Data Centers constructued in Sri Lanka have all considered an IT Load of more than 1 MW
• The next 6 Upcoming Data Centers will be designed for more than 2 MW
• Size for Higher Densities
• Current Data Center Rack Density in Sri Lanka is about 3kW on average
• Newer Implementations are seeing up to 8kW
• Global Averages for Rack Density are rising
• Large 2 Co-Lo Service Providers
• ~300 Racks X 8kW = 2.4MW
• Currently sized for ~1.5<MW (5kW per Rack)
• ~500 Racks X 8kW = 4MW
• Currently sized for 1.5MW expandable up to 2.5MW (5kW per Rack)

The Difference in Cooling

• Airflow
• 50 l/s (~106 CFM) per kW
• Human Comfort Airflow Levels and other Factors are irrelevant
• The Venturi Effect
• Whirlpools under Raised Floor
• CFD
• Engineering Value
• Validation and not just pretty pictures

Busducts and Busways

• Terminology
• Busbar
• Busduct
• Busway
• Why
• Busducts and Busways
• Longer Service Life
• High Availability
• Low Fire Load
• Better Resistance
• Reduced Loss of Energy
• Lower EMF
• No dependency on length
• Lower Points of Failure
• Busways Specifically
• Decentralized
• Footprint Savings
• Easy Maintenance
• Flexibility
• Plug-in Options
• Equal Distribution - Easy Planning

Fire Systems

• Fire Sealing
• Fire Detection
• EWSD / HSSD / VESDA
• Fire Suppression
• Clean Agent
• Dry Pipe Sprinklers
• Data and Equipment Protection
• Building Protection
• Human Protection
• Water Mist

SCALE!

Scaling: The surprising mathematics of life and civilization

Geoffrey West,

Distinguished Professor and Past President, Santa Fe Institute

My fist visit to Sri Lanka was in April 1956 on my way to London. I stayed at the Galle Face Hotel, their premier British-era hotel by the sea. I walked around the city of Colombo, impressed by the public buildings, many with stone facing undamaged by war. Because Mountbatten had based his Southeast Asia Command in Kandy, Ceylon had more resources and better infrastructure than Singapore.
