Description
The QLogic QL41254HLCU-CK is a powerful quad-port 10 Gigabit Ethernet adapter engineered to meet the stringent demands of modern data centers. Its four SFP+ ports provide flexibility in choosing the appropriate fiber optic transceivers (e.g., SR for short reach, LR for long reach), allowing for optimal network design and connectivity over various distances. This high port density is crucial for server consolidation, virtualization, and environments where maximizing network throughput per server is essential. Leveraging the PCIe 3.0 x8 interface, the adapter ensures sufficient bandwidth to support all four 10Gb/s ports simultaneously without contention. It incorporates advanced features such as TCP/UDP/IP checksum offloads and potentially other protocol offloads to minimize CPU overhead, thereby enhancing overall server performance and application responsiveness. This makes it particularly well-suited for I/O intensive workloads like high-performance storage, big data analytics, and high-frequency trading platforms. Designed for reliability and performance, the QL41254HLCU-CK is a key component for building scalable and efficient network infrastructures. Its ability to support diverse fiber optic connections via SFP+ cages, combined with its high throughput and offload capabilities, makes it a versatile solution for a wide range of enterprise and data center applications.
