The ICT sector now accounts for more CO2 emissions globally than the aviation industry (a little over 2% of the total global output). This is a concern to us, and something that we at VOZ believe needs to be addressed. While much of these emissions are caused by the use of monitors, data centres also account for a large percentage. This is why VOZ is working with GreenQloud to be truly green by hosting all our data at the world’s first 100% clean and renewable energy ISO 14001 certified data centre. Our servers are powered not by carbon credits as in other schemes but by clean, renewable energy.
Our servers are based at the Advania Thor Data Centre in Iceland which use a new type of natural free cooling technology, jointly developed with ASTmodular in Spain. The following information is taken from their website.
The lower container holds the racks while the cooling units are housed in the upper space. Outside air is pulled into the cooling unit which cools the air inside a closed air circulation system. In this way, no outside air comes into direct contact with the computer equipment inside the container.
High-density POD can provide up to 24kWh of natural free cooling.
The free cooling facilities within each container are designed to take into account the total load for all equipment currently hosted and future needs. The technology is a natural free cooling technology developed by ASTmodular in co-operation with Advania Data Centres. This technology gives Advania Data Centres the opportunity to run the data centre at very low PUE levels. Latest test results from our ASTmodular POD´s show a PUE result of 1.07.
Advania Data Centre is a Tier3 facility, as specified by the Uptime Institute, with dual connections to Iceland’s power grid. Power enters the building from two different locations, passes through redundant UPS backup batteries and N+1 diesel backup generators. The power feed is 400-800A to each POD and 16/32/64A to each rack. Power is monitored to the individual container and individual racks on request. The benefit of this enterprise class UPS system is its mean time to restore (MTTR) which enables the Operations team to replace individual modules with onsite spares. The N+ 1 system also combines “hot spares” so in the event of failure the modular system will automatically engage its redundant spare.
All network connections are double to each POD and house-in-house environment. Connections to the Internet are via multiple fibre cables provided by Mila and FarIce. Bandwith can be provided by multiple service providers and an Internet peering service in London and Copenhagen.. Advania Data centre can provide connections to its customers up to 100Gb.
