Why Choose This Product?

• 100Gbps HPC Connectivity: Gives compute clusters a high-bandwidth interconnect designed for demanding distributed workloads.
• Purpose-Built OPA Fabric: Intel Omni-Path Architecture is targeted at HPC and high-performance server clustering rather than general-purpose 1/10/25Gb Ethernet use.
• Low-Latency Communication: HPE specifies sub-microsecond latency for its 100Gb Intel OPA adapter family, valuable where node-to-node communication affects application runtime. 
• Core-Count Scaling: Its on-load architecture is designed to scale fabric performance as server processor core counts increase, helping align network capacity with compute density.
• Efficient Traffic Management: Fine-grain flow control and dynamic lane scaling provide mechanisms for optimizing traffic movement across supported OPA fabrics.
• HPE Platform Alignment: Designed for supported HPE ProLiant XL and DL server deployments, simplifying qualification within HPE-centric HPC environments.
• PCIe Flexibility: PCIe Gen3 x16 or x8 support provides installation options across compatible server expansion slots.
• Focused Deployment Economics: A single-port 100Gb adapter can provide a targeted high-performance fabric connection without purchasing unnecessary additional ports.
