2. Business Drivers for Datacentre Usage
• Cost Reduction
• Security
• Power Efficiency
• Disaster Recovery/Resilience
• Scalability (up and down!)
• Connectivity
• Reliability

3. What a modern Datacentre should provide
• Scalability – Future Proof delivery
• Power Density
• Power Efficiency
• Security
• Connectivity

4. TalkTalks Approach to the
Datacentre Challenge

5. Campus Layout

6. 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

7. 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

14. 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

16. 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?
