Système lame DLC bullx B700

ullx DLC blade system - B700 seriesbullx B700 DLC (Direct Liquid Cooling) blades offer revolutionary computing nodes for data centers. While providing anunequalled level of power for the most demanding applications, they also help reduce the data center’s electricity bills toenable organizations to innovate even faster and take the lead into the future.The exponential growth in power in supercomputers hasgone hand in hand with a strong increase in their powerconsumption over the past few years. On average, electricityaccounts for 28% of data center operating costs in Europe,and the significant increase in the price of a kWh expectedin the coming years will further accentuate the weight ofelectricity in the overall operating budget.Constant optimization of the PUE*In an attempt to keep operating budgets reasonable, Bull haslong been committed to providing ways of optimizing datacenter PUE*. Ideally, energy should be consumed only byservers, resulting in a PUE of 1.0. In practice, a data centerinvolves other electric equipment, notably air conditioningsystems, which means that even the most efficient only offera PUE of about 1.8.A first step towards PUE optimization consists in moving thecold production unit as close as possible to the equipmentto be cooled. Bull has been proposing this for several yearswith its cool cabinet. This technique enables PUE to bebrought as low as 1.4, without altering any of the ITequipment.Consumption reduced by a third with direct liquidcoolingTo further reduce the PUE, the servers must be redesigned sothat the heat generated by the main components can beevacuated by a liquid, as close as possible to the source ofheat. This direct liquid cooling (DLC) concept is implementedin the bullx B700 range: cooling occurs within the bladeitself, by direct contact between the hot components(processor, memory, etc.) and a cooled plate with activeliquid flow.Bearing in mind that a processor normally operates atmore than 50° and memory and SSD disks at more than40°, even water at room temperature is enough to coolthem. It is therefore no longer necessary to produce coldwater, which represents considerable savings in terms ofelectricity consumption, enabling a PUE of 1.1 to beachieved in optimal operating conditions.The B700 DLC blade system can evacuate far morecalories than a traditional blade system, making it ideallysuited for the market’s future generations of acceleratorsand processors.Unchanged serviceabilityThe bullx DLC cabinet contains all the equipment requiredfor the water circuits. It simply has to be connected to thesite’s room temperature water circuit. Inside the cabinet, aready-to-use closed water circuit evacuates the heat fromthe compute blades via a heat exchanger located at thebottom of the cabinet.Each chassis constitutes a closed water circuit that can beremoved for maintenance without shutting down the entirecabinet. Similarly, each blade is connected to the chassis’water circuit by dropless connectors, and can be removedas easily as any traditional blade, without stoppingoperating of the neighboring blades. To avoid contactbetween the water and the 230V electric lines, thehydraulic circuits are located at the bottom of the cabinetwhile the electricity supply is at the top.Furthermore, unlike many of the liquid cooling solutionsavailable on the market, the bullx B700 range uses totallystandard components: Intel ® Xeon ® processors, standardmemory bars and disks, which also helps to makemaintenance easier.Finally, for the comfort of all users, the bullx B700 DLCblade system is ultra-silent.A scalable range for the long termBased on an innovative architecture, the DLC blade rangeis designed to integrate the future generations of NVIDIA ®Tesla GPUs or Intel ® ’s MIC processors, as soon as theybecome available.* PUE (Power Usage Effectiveness) is the ratio between the energyconsumed by the entire data center and the energy consumed bythe actual servers.PRODUCT SPECIFICATIONSwww.bull.com/extreme-computing
