HPE 843420-001

Apollo InfiniBand EDR 100 Gbps Dual‑Port Mezzanine Gigabit Ethernet Adapter Refurbished

The HPE 843420‑001 is a high-performance dual‑port InfiniBand EDR (100 Gbps) mezzanine adapter designed for HPE Apollo and ProLiant XL compute blades. Based on Mellanox ConnectX‑4 technology, this adapter delivers ultra-low latency and high throughput, ideal for HPC clusters, storage fabrics, and compute-intensive environments. Its mezzanine form factor connects directly into server blade trays, optimizing thermal and I/O performance. Refurbished and warranty-backed, it provides a cost-effective path to seamlessly integrate EDR-level InfiniBand into existing infrastructure.

Features

Designed for high-performance environments, this mezzanine adapter supports two InfiniBand EDR links at 100 Gb/s each, enabling rapid data movement across node-based clusters. Built on Mellanox ConnectX‑4 silicon, it supports features like XRC, DCT, UMR, and ODP for scalable and efficient communication protocols in HPC workloads . It fits HPE Apollo XL230k Gen10 and XL260a Gen9 compute trays using the proprietary FIO mezzanine slot, preserving PCIe lanes for other server board functions and improving airflow and density

Advanced Options

This adapter enables consistently fast, reliable data transfer across HPC and storage clusters. With InfiniBand EDR throughput at 100 Gbps per port and advanced offloads like XRC, DCT, and UMR, it ensures scalable performance with minimal CPU overhead
