About the HPE Cray EX254n

The HPE Cray EX254n liquid-cooled blade compute node delivers high-density processing within a compact HPE Cray EX blade form factor, supporting dual AMD EPYC 3rd Gen processors with 16 DDR4 DIMM slots per node—8 per socket—for substantial memory headroom in demanding HPC and AI workloads. This node integrates seamlessly into HPE Cray EX4000 and compatible EX chassis systems, where direct liquid cooling (DLC) technology manages thermal density while maintaining operational efficiency across enterprise-scale deployments.

HPE engineered the EX254n for high-performance computing teams, research institutions, and AI infrastructure teams that require proven, integrated platforms for simulation, analytics, and machine learning at scale. The node connects via HPE Cray Slingshot interconnect technology at 200 Gb/s per port, supporting both Dragonfly and Fat-tree network topologies to eliminate bottlenecks in tightly coupled parallel workloads. Management operates through HPE Cray System Management (CSM), while the HPE Cray Programming Environment (CPE) and support for HPE Cray OS (COS) and SLES for HPC provide a unified software stack that reduces deployment complexity and accelerates time-to-science.

Organizations selecting the EX254n (part number P28487-B21) benefit from HPE's integrated approach to liquid cooling, processor density, and purpose-built interconnect architecture—eliminating the fragmentation of bolt-on solutions. Omnixon Global supplies the complete HPE Cray EX family to enterprise customers throughout the UAE and GCC region.
