Marvell Technology Group Ltd. QL41234HLCU Network Adapter

Marvell QLogic QL41234HLCU is a four-port 25Gbps SFP28 network adapter that provides four independent 25GbE links in a single card. The package includes four SFP28 transceiver modules, enabling immediate connections to compatible 25GbE switches or networked storage backplanes. This high-density card is designed for data-center servers and virtualized environments that require substantial aggregate bandwidth and low-latency traffic across multiple network paths. Each port operates at 25 Gbps, supporting parallel data streams for workloads such as virtualization, cloud-native apps, and large-scale data transfers. The four-port layout enables flexible networking topologies, including dedicated links for separate storage, management, or back-end traffic alongside front-end connections. As part of the Marvell QLogic family, the QL41234HLCU is built to integrate with standard 25GbE optics and server networking setups, delivering a scalable path to higher throughput in dense server deployments.
