MCX653105A-ECAT InfiniBand HDR100 / 100GbE QSFP56 Network Adapter

The HPEP24251-001 MCX653105A-ECAT card is a high-performance single-port InfiniBand HDR100 and 100 GbE QSFP56 Network Adapterbuilt for next-generation cluster and data center environments. With PCIe 4.0 ×16 (or ×8) host interface, it delivers ultra-low latency and full duplex 100 Gb/s throughput, ideal for HPC, storage clusters, virtualized applications, and AI workloads. This adapter supports both HDR InfiniBand and Ethernet modes over QSFP56, offering flexible deployment options. Compatible with HPEProLiant DL Gen10 Plus, Apollo, and Synergy servers, it ensures seamless integration while reducing CPU overhead with advanced offload engines.

Features

This HDR100/Ethernet adapter uses a QSFP56 port supporting DAC and AOC cables for flexible direct server or switch interconnects. It delivers line-rate throughput with sub-microsecond latency, making it well suited for high-performance messaging, inter-server traffic, and low-latency storage access scenariosEquipped with advanced offloading×including MPI tag matching, rendezvous, and adaptive routing×the adapter dramatically reduces CPU load during compute-intensive operations. Its PCIe Gen4 architecture supports maximal performance, while a low-profile bracket ensures compatibility with space-constrained server chassis

Advanced Options

This adapter is engineered for demanding network environments requiring high reliability and performance. It delivers full 100 Gb/s data rate with sub-microsecond latency when paired with HDR InfiniBand or 100 GbE switches, enabling real-time cluster communication. Reducing CPU overhead through intelligent offloading ensures maximum compute efficiency for workloads like AI training or distributed storage. The PCIe Gen4 architecture combined with Mellanox ConnectX-6 silicon supports both legacy and modern server platforms.
