HPE P23665-H21
InfiniBand HDR100 / Ethernet 100Gb 1‑Port QSFP56 Adapter
The HPE P23665‑H21 is a high-performance 1‑port InfiniBand HDR100 and Ethernet 100 Gb Adapter based on MellanoxConnectX‑6 technology. Designed for HPC clusters and enterprise data centers, it offers ultra-low latency and full-duplex 100 Gbps throughput. Suited for latency-sensitive workloads like AI training, high-speed storage access, and cluster interconnects, this Adapter features a QSFP56 interface compatible with DAC or AOC cabling. Its low-profile PCIe 4.0 ×8 bracket makes it ideal for space-constrained server environments. Whether deployed with HPE ProLiant DL Gen10/Gen10 Plus or Apollo platforms, it ensures predictable performance with advanced offloading and scalability features.
Features
This Adapter delivers line-rate InfiniBand HDR100 or Ethernet 100 Gb connectivity via a QSFP56 port, supporting both direct attach copper (DAC) and active optical cable (AOC). Its PCI Express Gen4 ×8 interface enables maximal throughput with low latency, making it suitable for high-bandwidth inter-server or server-to-switch links. With built-in hardware offloads—such as MPI tag matching, rendezvous, and adaptive routing—the Adapter reduces CPU utilization, boosting performance for HPC or virtualization workloads. Its plug-and-play architecture and compatibility with major server models simplify deployment in modern clusters and data center networks.
Advanced Options
Engineered for reliability in mission-critical HPC and enterprise environments, this Adapter achieves full 100 Gbps line rate with sub‑microsecond latency when paired with HDR switches. The PCIe Gen4 ×8 interface ensures consistent bandwidth while minimizing CPU overhead through advanced offload engines. Hardware support for MPI tag matching, rendezvous, and adaptive routing enhances cluster communication and fault resilience.
