A two-phase immersion cooling (2PIC) project – which will be the world’s most powerful – is being undertaken in the Republic of Georgia for use in a 40+ MW data center which is being developed by BitFury Group. Recently acquired Hong-Kong-based engineering company, Allied Control, are designing and building the system, which will use a top-of-the-range immersion coolant, 3M™ Novec™ 7100 Engineered Fluid, to efficiently cool the data center.
Bitcoin blockchain infrastructure provider and transaction processing company, BitFury Group is aiming to reduce its carbon footprint and operational costs by improving efficiency and saving energy. BitFury produce their own custom ASICs, PCBs, servers and data centers and will be using Allied Control’s 2PIC technology with Novec fluid to deploy 28nm and 16nm ASICs. Vice-president of operations at Allied Control, Kar-Wing Lau said they had yet to reach the limits of the system and the technology provided the ability to grow quickly, spreading the cost of the cooling system over many years.
Since 2010, 3M engineered fluids have been used in server cooling of various situations and have made a name for itself as being extremely energy efficient. The process revolves around using fluids with low boiling points (Novec 7100 boils at around 60°C) to surround the hardware. As the components heat up, the change in state of the coolant draws the heat out of the hardware and the vapor rises to condense on a water-cooled condenser before falling back into the tank without being pumped. Energy saving in these systems has been stated to be up to 95%.
CEO of BitFury, Valery Vavilov, stated “The PUE we’ve achieved leads us to the next level of data center cooling for high performance computing. We’ve taken many steps to optimize our infrastructure for securing the blockchain and blockchain transaction processing that have led us to many different technological innovations. These experiences and technologies could be useful for next generation data center constructions of high performance computing and supercomputing.”
Currently the project is scheduled to support 40MW of IT load running at 1.02 PUE; however it is planned to increase soon. 3M is also due to have a demonstration tank at the 2015 Supercomputing Conference (SC15) in Austin, Texas, using 2PIC with Novec 7100 fluid. The partnership should allow the industry to support a growing power processing need for high performance computing.
BitFury was founded in 2011 by Valery Vavilov and Valery Nebesny and has management offices in San Francisco, Washington, D.C., Hong Kong and Amsterdam, as well as data-centers in Iceland and the Republic of Georgia.
