Beyond pure performance, supercomputers must not just leverage the latest technologies, but also perfectly meet the needs of applications and users. Atos’s HPC R&D has designed the BullSequana X series of servers to provide maximum flexibility in terms of interconnect, power, and cooling, and cover the widest possible spectrum of applications. BullSequana X supercomputers offer an infinitely adaptable response, with a large choice of compute nodes, accelerated nodes and specialized nodes. And this multitude of components can be combined, in a completely customized way, into a single system and managed as a single system using the Bull supercomputer suite.
BullSequana X1000 open supercomputers
Designed by Atos’s R&D in close cooperation with major customers, the BullSequana X1000 supercomputer leverages the latest technological advances, so as to guarantee maximum performance for a minimized operation cost. BullSequana takes up the exascale technological challenges:
► Open for future technologies
► Limit energy consumption
► Handle the data deluge
► Accelerate application performance
► Deliver a resilient system
BullSequana X1000 cell
In BullSequana X1000, the computing resources are grouped into cells. Each cell tightly integrates:
► compute nodes,
► interconnect switches,
► redundant power supply units,
► redundant liquid cooling heat exchangers,
► a dual node for distributed management and diskless support.
This packaging consisting of large building blocks facilitates high-scale deployment – up to 64.000 nodes, and optimizes density, scalability and cost- effectiveness.
MORE INFORMATION ON THIS PRODUCT
The BullSequana X1000 cell is organized across three cabinets.
► the two side cabinets contain compute nodes,
► the central cabinet houses the interconnect switches.
Limiting energy consumption
Controlling energy consumption is the main roadblock on the path to exascale. BullSequana X1000 is ultra energy-efficient: it targets a PUE very close to 1.
100% of the components of BullSequana X1000 – both compute nodes and switches – are cooled using an enhanced version of the Bull patented Direct Liquid Cooling (DLC) solution. DLC is a proven cooling technology that minimizes the global energy consumption of a system by using warm water up to 40°C.
The cooling system of BullSequana X1000 is sized to evacuate the heat generated even by the most extreme configurations – with very powerful and energy-hungry nodes.MORE INFORMATION ON THIS PRODUCT
For easy maintenance, all Bull Sequana X1000 components (compute nodes, interconnect switches, PSUs, heat exchangers…) are hot-swappable and can be serviced without interrupting system production. In the compute blades, the processors and DIMMs can be replaced without removing the cold plate. In a BullSequana X1000 cell, all maintenance operations are just as easy as in a standard air-cooled system.MORE INFORMATION ON THIS PRODUCT

BullSequana X800: at the confluence of HPC and Big Data
Featuring an architecture that supports an impressive number of processing cores and an exceptional memory capacity, the BullSequana X800 servers are engineered for high performance and in-memory computing. They are ideally suited to support massive in-memory data bases, pre-processing, post-processing, and visualization. They are among the most scalable and modular ultra-high memory servers on the market, starting with 2 CPUs and 24 memory DIMMs, and going up to 32 CPUs with 384 memory DIMMs in 16 interconnected boxes – with a linear performance scaling.
A powerful and modular range
The BullSequana X800 series consists of five complementary models, assembling 1 to 16 2-socket compute boxes thanks to two types of interconnects:
- A glueless interconnect is used for 1, 2 or 4 compute boxes, allowing to form a glue-less configuration with up to 8 sockets.
- For larger configurations, a UNC (UPI Node Controller) stacks 8 to 16 boxes.
This distinctive Atos technology makes it possible to form 16- or 32-socket servers.
A Connecting Box assembles compute boxes with no apparent cabling, and makes it possible to easily add compute and memory resources. This helps adjust memory and compute resources to application needs, and facilitates the scaling of Big Data applications. For more agility in configuring, BullSequana X800 servers feature hot plug I/O blades, disks, fans and PSUs.More information on this product
Key innovative components
Each compute box is a 2U 2-socket rack server and contains:
- up to 24 memory DIMMs, i.e. a total of up to 3 TB per compute module when using 128GB DIMMs – and ready for higher capacities with future memory technology;
- hot plug I/O blades that offer up to 5x PCIe Gen3 slots, with capability for a disk controller in charge of the front-end disks;
- a number of options to customize the system to match application requirements: internal disks, NVMe drives or GPUs.
