Bull Extreme Computing Catalogue

bullx blade chassis

• High density, uncompromised performance and optimized power consumption

The bullx blade chassis can host up to 18 compute blades in 7U. It also contains the first-level interconnect, a management unit and all components necessary to power and cool the blades, interconnect and management unit. It is the ideal foundation to build a medium to large-scale HPC cluster, with bullx compute blades combined with R423 E2 service nodes.

18 blade slots (for 18 single-width blades or 9 double-width blades)
