    Telstra is in the process of revamping a 10-year-old building shell in London to support a modern high-efficiency datacentre, with the help of consulting company On365.

    The Australia-based telecoms and colocation company has datacentres across the world. Its Docklands-based facility is targeted at customers who need guaranteed connectivity, as it links to Telstra's 400Gbps dense wavelength division multiplexing (DWDM) London fibre ring.

    The first stage of the revamp is bringing hot aisle and cold aisle containment to every floor of the nine-floor datacentre to maximise power usage effectiveness (PUE). As it stands, the PUE of the centre is 1.6, as Telstra has already modified five of the floors, with another four of the floors to go.

  • As Telstra is a colocation supplier its customers have a variety of rack hardware

    The upgrade to the 114,250-square foot site is an attempt by Telstra to claw back power by getting rid of inefficiencies in cooling.

    The goal is to grab back around 50 to 60KW from cold aisle containment on each of the facility's nine operational floors. With this, as well as upgrades to the uninterruptible power supply (UPS) system, Telstra hopes eventually to get around a megawatt of power back.

    One of the few bits of hardware that can give Telstra trouble with controlling the temperature differential between the hot aisle and cold aisle is a type of switch from Cisco that is popular with customers. The Cisco 7600 series of routers have a tendency to blow air out of the front, which proves a headache for heat management, Kevin Sell, head of technical facilities at Telstra International, told ZDNet UK.
