                                                   Dave Mullender
-   Discussions                           Head of Network Services
Business Drivers for Datacentre Usage
  • Cost Reduction
  • Security
  • Power Efficiency
  • Disaster Recovery/Resilience
  • Scalability (up and down!)
  • Connectivity
  • Reliability
What a modern Datacentre should provide

•   Scalability – Future Proof delivery
•   Power Density
•   Power Efficiency
•   Security
•   Connectivity
TalkTalks Approach to the
Datacentre Challenge
Campus Layout
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
Datacentre Module rollout

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
The TalkTalk UK network



        LLU exchange

        Planned LLU
        exchange
        Nodes

        20Gbps rings
        800Gbps rings
        1.6Tbps rings
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?
