HPE843400-B21

InfiniBand EDR 100 Gbps 2-Port Gigabit Ethernet Adapter- Refurbished

The HPE843400-B21 (840z 2-port Mezzanine FIO adapter) is a refurbished InfiniBand EDR network card engineered for high-performance computing and ultra-low latency interconnects. Based on Mellanox ConnectX-4 technology, it delivers 100 Gb/s per port throughput over InfiniBand EDR links. Suitable for HPC clusters, HPC-optimized storage, and advanced compute applications, it integrates into HPEApollo and ProLiant XL server compute trays. This adapter optimizes data fabric performance and supports enterprise-grade InfiniBand features, enabling scalable throughput and efficient communication for demanding workloads.

Features

Designed for HPC environments, the adapter installs as a mezzanine card in HPEApollo and ProLiant XL compute blades, bypassing conventional PCIe lanes for direct high-speed interconnect access. It leverages Mellanox ConnectX-4 silicon to support InfiniBand EDR at 100 Gb/s per port, minimizing latency while maximizing bandwidth. Features like Extended Reliable Connected (XRC), Dynamically Connected Transport (DCT), user-mode registration (UMR), and on-demand paging (ODP) enable scalable memory sharing and efficient communication between nodes

Advanced Options

Engineered for mission-critical and cluster-grade performance, this adapter ensures dependable, low-latency inter-node messaging. Compliance with IBTA 1.3 and support for enterprise software tunnels like XRC and DCT facilitates robust data transfer under HPC workloads
