Newly developed enhancements to Interoute’s Geneva data centre reduce its energy consumption by 1.7GW hours per year
Phil Martin, VP for Network Services Engineering at Interoute, commented, “We are delighted to receive The Giga Trophy which rewards companies’ work to reduce energy consumption within their local communities. The amount of energy we now save annually is enough to power a small Swiss village for a year. Becoming more energy efficient not only benefits the environment, it also helps us manage costs and make our services more competitive saving hundreds of thousands of Euros each year.”
Interoute has achieved the energy savings by implementing a variety of cooling and power improvements. These include:
- A custom-made cold aisle containment system. Approximately 1,000 racks in the data centre were each fitted with custom-made cold aisle containment doors and panels. The new system means that only the racks are cooled rather than the whole room, which in turn reduces overall energy expenditure. It ensures consistent and predictable airflow to eliminate server hotspots. It also enables the introduction of specific set temperatures to create the most efficient operating environment for the IT equipment in each aisle.
- Unique under-floor cooling pathways. The team further augmented the cold aisle containment system by building sealed pathways under the raised floor to ensure cold air was sent directly to the containment systems. Likened to a complex geometry challenge, the result has approximately halved the amount of underfloor space needing to be cooled, providing a considerably energy saving given the 2,200m2 data centre footprint. The pathways also accommodate technical requirements such as cable trays for fibre and copper wiring and space for fire detection systems.
- A new and enhanced cooling system. The existing 58 cooling units that used a fixed fan speed have now been adapted to accommodate variable fan speeds. This enables fan speeds to be accurately matched to demand, in order to avoid excess power usage. In addition to this, the data centre has been fitted with new 1.2MW free cooling infrastructure. On cold days this brings in air from the outside to help cool down the IT equipment, reducing the need for powered cooling units even further.
- Introduction of static Uninterruptible Power Supply (UPS) systems. Half of the existing rotary UPS systems have been replaced with new, static UPS systems, which are more energy efficient.
- Re-balancing of IT loads. Where possible, servers have been consolidated and loads concentrated into fewer racks, enabling cooling and equipment to be shut down in emptied areas.
