Achieve optimum sovereignty, security and savings by combining BullSequana SH servers and Vates virtualisation Management Stack (VMS)

BullSequana SH brings virtualisation to the most demanding workloads, enabling higher virtual-to-physical consolidation, better resource utilisation, fewer managed hosts, and reduced licensing costs.

At the heart of this performance are Intel® Xeon® processors, featuring built-in accelerator engines that speed up data movement and optimise load balancing to enhance virtualisation efficiency. These accelerators consolidate workloads while delivering exceptional performance for highly transactional applications and large-scale data analytics, helping you achieve faster insights and greater operational agility.

BullSequana SH combined with Vates VMS delivers:

  • High memory capacities for demanding workload
  • Better suited for memory intensive applications (databases, analytics, big data, …)
  • Large VMs with high vCPU counts
  • Faster inter-VM communications than using external ethernet networks
  • Increase resource usage ratio due to higher degree of VMs consolidation
  • Reduce number of managed physical servers
  • Reduce network complexity and connection points
  • Reduce power, cooling and space requirements
  • Flexibility to scale-up (adding CPUs in servers) and scale-out (adding hosts in clusters)
  • Vates VMS per-hosting pricing eliminating hidden costs

FAQ

 Virtualisation is the process of creating virtual versions of physical resources, such as servers, storage, and networks, allowing multiple workloads to run on shared hardware. It improves efficiency, scalability, and cost control while enabling flexible, secure IT environments. 

This partnership delivers European-designed hardware and open-source virtualisation, ensuring compliance, transparency, and full control over IT infrastructure.

 Vates licensing model eliminates per-socket fees, and Bull validated reference designs minimise integration and maintenance costs. According to our simulations we can expect a reduction of TCO from 60 to 80% compared to VMware’s solution. 

 Yes, Vates VMS integrates with OpenStack, Ansible, Terraform, and Kubernetes for flexible, API-driven orchestration. 

Customers benefit from coordinated lifecycle management and support from both Bull and Vates, ensuring reliability and ecosystem integration.

As an open-source product, components of the solution can be freely downloaded. Trial licenses are also available to get better support and extended feature set.

1000+ customers in all regions, including very high demanding businesses and service providers.
