  • Resilience

    This new facility in South West London completes Digital Realty's 'Surrey Triangle', which includes sites in Woking and Redhill.

    Each of the datacentres are connected to each other so that a backup from another site can be provided in case of an outage.

    However, all of the sites have been designed with a certain level of resilience built in. For example, Chessington has diverse network feeds and power supplies that enter the property from opposite ends in case one of the feeds experiences a problem.

    The site is protected by a range of security features, including 29 round-the-clock CCTV cameras a raised perimeter fence and 24/7 manned gate. Access to the datacentre is controlled by key cards and biometric sensors. 

    Datacentre resilience is measured on a tiered scale that goes from one to four, with one being the least resilient and four being the most. A Tier 3 datacentre has an expected availability of 99.982 percent uptime and features such as a dual power supply, in line with standards set by the Telecommunications Industry Association.

  • Five data halls

    Each data hall has staging workspace for technical operations, with lift access, power and cooling facilities throughout.

    The vast data halls are also kept cool with the help of 14 CRAC (computer room air conditioning) units that can be found operating in an N+2 configuration (providing back ups) in each of the 10,000 square foot pristine data halls. 

    The datacentre halls are raised 4m above ground level and have an 800mm raised floor. The floor can take loads of up to 12.5KN/m².

  • Power

    The blue and orange units are used to house the power and networking feeds that enter the data halls from opposite ends of the building. 

    The datacentre is powered by a 1.4MW uninterruptible power supply (UPS) but it also has a dedicated 18MVA electricity sub-station based on site as a backup.
