Infrastructure

In partnership with BlueSquare Data Group now Pulsant Ltd, PoundHost operates from four, state-of-the-art Data Centres based in the UK. Each Data Centre has been over-engineered from the ground up for resilience and redundancy. Utilising best-in-class hardware from diverse providers over multiple paths allows us to offer you a 99.9% guaranteed uptime SLA.

In 2011 we celebrated our first ten years in the dedicated and co-location hosting business and look forward to many more.

Our New Data Centre

Our new data centre site is a 50,000 square foot facility located in the heart of the Thames Valley, near to the Green Park technology area.
Our phase 1 build has 10,400 square foot split over 2 data halls.

  • Main electrical panel

    Main electrical panel 'A' and 'B' side

    This is part of the main electrical panel feeding the 'A' and 'B' side of our power infrastructure. Everything is duplicated so that every server has two completely independent power feeds for redundancy. We colour-code the panels for easy identification; 'A' is black and 'B' is orange. In the photo you see the automatic controller which starts the generators and transfers to generator power in the event of a mains failure.

  • HV Transformers & Generators

    HV Transformers & Generators

    Here you can see the 'B' side transformer, with the 'A' side transformer and generator in the background. The overhead gantry carries our busduct - this conducts the power from the transformers/generators back into the building and is a more efficient solution than using copper cables

  • Diesel Generators

    Diesel Generators

    We have multiple SDMO 1.1MVA generators for emergency power provision. They are tested monthly, and are configured in an N+1 set up. This means that in the unlikely event the mains power fails, we can tolerate the failure of a generator and still support the entire data centre load.

  • UPS Batteries

    UPS Batteries

    This is the 'A' side room of UPS batteries, and is duplicated on the 'B' side. There are further strings of batteries out of frame, and the batteries support the power to the servers if there is a transient or disturbance on the mains load, or alternatively in the time it takes for the generators to start up and support the load.

  • 400kVA UPS

    400kVA UPS

    This is one of our 400kVA UPS units. The UPS filter and clean the power through an inverter/rectifier and isolation transformer, so the power supplied to the servers is stable and reliable.

  • Fire control panel

    Fire control panel

    In this photo you can see the manual release control for the gas extinguishant system. This is part of our fire detection and control system for the data centre, and allows us to manually release the gas extinguishant to put out any fire if one should develop.

  • Fire beacons and sounders

    Fire beacons and sounders

    When you visit our data centre you will notice the data floors are quite a noisy environment with all the servers operating. For health & safety, we therefore have a large number of fire beacons and sounders to alert any personnel to evacuate the area.

  • Air conditioning inlet

    Air conditioning inlet

    These louvers allow the cold air into the data floor. On the other side of them are the air conditioning units that take the hot air from the servers, cool it, and then recirculate it into the room. The hot air is ducted from the top of the server racks and into the ceiling.

  • Fire extinguishant bottles

    Fire extinguishant bottles

    We have a total of 85 bottles, each 80 litres at 300 bar pressure of fire extinguishant. We use the environmentally-friendly mix of 50% argon and 50% nitrogen. When these are released, they reduce the oxygen levels in the room so that any fire cannot be sustained.

  • Air conditioning unit

    Air conditioning unit

    One of our air conditioning units. Each unit can cool over 250kW of heat at peak usage, although we normally run the units at much lower load because we have an N+2 configuration. This means that two units can fail or be taken out of service for maintenance, without impacting on the overall performance of the cooling system.

  • Heat rejection equipment

    Heat rejection equipment

    The chilled water pipework takes the warm water from inside the data centre, and returns it into the data centre as cold water. To remove the heat from the water we use a free cooling chiller combination with high surface area for extra efficiency.
