HPE P26155-001

Dual‑Port 100 Gb QSFP56 Ethernet Network Adapter (Mellanox MCX623106AS-CDAT)

The HPE P26155‑001 is a dual‑port 100 GbE Network Adapter using the Mellanox MCX623106AS-CDAT (ConnectX‑6 EN) chipset and PCIe 4.0 ×16 interface. Capable of delivering up to 200 Gbps aggregate throughput, it supports advanced features such as RoCE, SR‑IOV, Data Plane Development Kit (DPDK), and tunnel offloads (VXLAN/NVGRE/GENEVE). Ideal for modern data centers, virtualization, cloud, HPC, or storage fabrics, this adapter enables ultra‑high bandwidth, low-latency communication across dual QSFP56 ports with full diagnostics support. Compatible with HPE Gen10+ and Gen11 servers, it’s designed for scalable high‑performance deployments.

Features

Based on Mellanox ConnectX‑6 EN, each QSFP56 port delivers 100 Gb/s, enabling up to 200 Gb/s aggregate bandwidth across both ports. It aligns with IEEE 802.3by/bj/bm/ba standards and supports RDMA over Converged Ethernet (RoCE), SR‑IOV, GPU Direct, and acceleration features like DPDK, VXLAN, NVGRE, and GENEVE tunneling With PCI Express 4.0 ×16 interface, the adapter ensures full-speed data delivery to host systems, leveraging modern server platforms. Integrated Digital Optical Monitoring (DOM) provides real-time insight into voltage, temperature, and link status. At a typical power draw of around 13 W, it balances performance with thermal efficiency, making it suitable for dense deployments in HPE ProLiant Gen10+ and Gen11 servers.

Advanced Options

This adapter delivers enterprise-grade reliability and performance with support for full 100 Gb Ethernet throughput per port and sub-microsecond latency. Hardware offloads significantly reduce CPU utilization, making it ideal for virtualization, cloud-native applications, and high-speed data services. DOM-enabled diagnostics assist in proactive monitoring of link integrity and environmental conditions.
