HPE 840134-001
Ethernet Card 100gb Single-Port 620QSFP28 Network Adapter
The HPE 840134‑001 (also known as 817762‑B21) 620QSFP28 Network Adapter provides ultra-high-performance networking with a single QSFP28 port that carries four independent 25 GbE lanes. It’s engineered for modern data center servers,especially HPE ProLiant Gen10 and Apollo series, delivering 100GbE bandwidth in a compact, low-profile design.
Features
This adapter leverages the QLogic (now Marvell) 45604 chipset to deliver robust performance and extensive offload features—including RoCE, SR‑IOV, and jumbo frames—for latency-sensitive workloads like virtualization, HPC, and cloud computing
Advanced Options
Although the QSFP28 port structure suggests 100Gb operation, most implementations deliver four discrete 25 GbE links rather than a single 100GbE channel.The card includes an active cooling fan to stabilize temperatures in dense server environments, ensuring consistent throughput under full load.
Product Key Features
-
1 × QSFP28 port supporting 4 × 25 GbE lanes (up to 100 Gb/s aggregate)
-
QLogic/Marvell 45604 chipset for proven performance and reliability
-
PCI Express 3.0 x8/x16 host interface (depending on bracket)
-
Supports RoCE, SR‑IOV, VLAN, jumbo frames, RSS, MSI‑X offloads
-
Low-profile form factor, active onboard fan for thermal control
-
Compatible with HPE ProLiant Gen10 servers and Apollo line
Reliability & Performance
Installation is straightforward—usually via PCIe 3.0 x8 interface (though x16 brackets exist)—and both low-profile and full-height versions are available for flexible integration across server designs.. It delivers advanced networking offloads such as TCP/UDP/IP checksum, TSO, RSS, LSO, and PTP support, minimizing CPU load and maximizing packet processing efficiency.. Compatible with virtualization platforms like VMware, Microsoft Hyper‑V, and Linux distributions, this adapter is trusted for enterprise-scale reliability and versatility.
