BullSequana S servers

High performance

To harness the vast capabilities of AI, enterprises need an infrastructure with extreme performance. BullSequana S features a unique combination of state-of-the-art Intel® Xeon® Scalable processors and GPUs. This innovative architecture, developed by the Atos research teams, allows GPUs, storage and compute modules to be combined in a single server to support all workloads


The new generation of x86-based BullSequana S™ servers are designed to solve enterprise IT challenges and enable companies to fully leverage artificial intelligence, optimized for machine learning, mission critical business applications and in-memory environments such such as SAP HANA

Flexibility and scalability

BullSequana S is the most flexible, scalable and open platform for digital business development. With dynamic configuration options, from 2 to 32 CPUs / up to 48 TB of RAM / up to 32 GPUs, it combines exceptional performance with unrivaled flexibility to increase operational efficiency at all levels

Advantages of BULLSequana S servers


Excellent scalability

BullSequana S single technology can be used for any deployment - from SAP HANA - from 384GB to 12TB of RAM to building enterprise artificial intelligence. BullSequana S features a unique combination of the latest Intel® Xeon® Scalable processors and graphics processors. This approach protects your investment by enabling you to migrate to any SAP HANA architecture for any size project

Maximum flexibility

The ability to reuse existing modules (e.g., storage) and combine existing and new modules provides the flexibility needed to reduce usage costs. BullSequana S servers are certified for SAP HANA in both Appliance and Tailored Datacenter Integration (TDI) modes. Appliance mode offers pre-integrated hardware, storage resources, and software for rapid deployment. In addition, centralized support and consistent performance metrics are provided. TDI mode allows you to select any storage technology certified by SAP under the TDI program or use an existing SAN system.

Mainframe-level reliability

BullSequana S servers support unique memory protection features required for mission-critical systems. With a patented blade system, memory and PCIe components support hot plug and swap capabilities to simplify maintenance and provide best-in-class availability.

Computing module

Compute module with 2 CPUs, up to 3 TB RAM and NV-RAM capabilities (up to 7.5 TB), contains up to 8 disks (2.5") and PCIe hot plug/swap functionality for easy maintenance. The 2U form factor makes the solution dense, and the free space allows you to add additional modules to optimize flexibility: storage devices or GPUs.

Graphics processor for artificial intelligence

The module is designed to utilize up to 32 GPUs in a single server, 2 units per module. Real-time algorithms and machine learning will utilize this enormous processing power in their work.

Storage devices for handling large amounts of data

  • Professional engineers will perform the installation and final configuration in the customer's network
  • Support is provided through a single point of entry
The module can support: 12 SAS/SSD 2.5" disks; 4 high-capacity NL-SAS 3.5" disks; 4 NV-Mem for high I/O throughput. With the additional storage, the capacity reaches 20 disks in a 2U form factor and more than 2 PB in a server with 32 CPUs. All of these will be used in applications ranging from data lake to virtualization.

The servers come with a standard 3-year warranty. Made in France.
By combining the latest and unique technologies, bullion is the only x86-based servers that can respond flexibly, securely and cost-effectively to all your needs.

Built on a robust, powerful and modular architecture - supporting from 2 to 16 Intel® Xeon® E7 v4 processors and up to 24 TB of memory - bullion servers combine the incompatible: high performance, flexibility, reliability and cost-effectiveness.

Powerful and scalable lineup

Modules are integral parts of BullSequana S servers. Each module can be removed from the compute unit for easy maintenance. A module includes a compute unit and (optionally) a memory or graphics processor module.BullSequana S. Each module can be removed from the compute unit for easy maintenance.
