Campus Scalability
• 14 Hectares of space• 114MVA of power available• More than 7000 racks over 5 buildings• 4 Tbits/second of configurable connectivity
over multiple diverse fibre connections

Modular Design
• Modular Design– Build offsite in a reliable and consistent manner– Minimal works onsite– Very short build schedules– Provides the ability to flex to future changes in
requirements

Power Efficiency
• Adiabatic cooling provides dramatically more efficient cooling than traditional DX
• PUE of 1.2 compared to industry average of over 2• 99.7% of the year cooling is provided by fresh air

Discussions
• A cloud service is only as good as the connectivity and storage facilities it runs from?
• Do you need to know where your service is delivered from?
• Does QoS matter?
