How a Next Generation data centre can make all the difference when hosting

Dave MullenderHead 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

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?
