QBx
High Efficiency
Computing Clusters

Efficience by design
• Higher density
• Optimized energy efficiency
• Limited carbon footprint

Qarnot's QBx is a computer module optimized for both high performance computing and energy efficiency:

• Designed with the most efficient form factor
• Each module integrates 12 to 24 processors whose intensive computing heats water
• Valorizes up to 95% of computer waste heat by producing hot water
• Modular approach allows for the addition or removal of computing power without disruption of service
• Quiet operation with no moving parts

The QBx dramatically increases the energy efficiency of both traditional high-density data centers and edge infrastructures.

High density

• Based on OCP servers Leopard/Tioga Pass/Capri with AMD Epyc and Intel Xeon CPU.
• Each module can deliver up to 5 kW of digital power
• Enabling 6 kW/m2 density

Cost-effective

The global bill per core can be drastically reduced with a technically and energetically sustainable architecture:

• avoiding most of the data centers’ CapEx (construction, cooling infrastructure, redundancy, ...)
• and OpEx (cooling, ...)
• With a simplified cluster module approach, operation and maintenance is also highly optimized

Carbon footprint

ESG impact becomes central for every corporation and IT CapEx & OpEx take a growing role in the industry’s carbon footprint. On most items involved in sustainable goals accounting, Qarnot QBx brings efficient and uncompromising solutions:

• Direct high water flow cooling with PUE below 1,01 and WUE of 0
• Industrial design optimized Energy Reuse Factor up to 95% and ERE of 0,05
• Designed to be deployed in “standard” buildings avoiding data center construction
• Open Compute (OCP) architecture allows hardware reuse and sustainable decommissioning
• Automated control of hardware power and frequency to fit energetical and thermal constraints

Fire protection and safety

• Insulated and hermetic design with limited air volume inside
• Absence of moving parts that could be the cause of a fire
• Pipe junctions located in non-sensitive volumes
