By the numbers: Telstra's London datacentre
Summary: Telstra's Docklands datacentre is being revamped to bring hot and cold aisle separation to its racks and has plans to create a large heat exchanger in the future to further boost efficiency
Telstra's datacentre in London's Docklands is being revamped to bring hot and cold aisle separation to all of its racks.
As Telstra is a colocation provider, it has no direct control over the hardware its customers use, but it can enclose the racks to boost the temperature difference between hot and cold air. The firm has plans to use the nearby waters of the Docklands to increase its energy efficiency by creating a heat exchanger, and is discussing this with British Waterways.
