Product Description
The QLogic QL41212HLCU-CK represents a significant step up in network performance, offering dual-port 25 Gigabit Ethernet connectivity. This adapter is engineered for environments that demand extreme bandwidth and low latency, such as those supporting artificial intelligence (AI), machine learning (ML), high-performance computing (HPC), and high-speed storage solutions. The use of SFP28 cages allows for flexible deployment with various fiber optic transceivers, enabling connectivity over different distances and media types. Equipped with a PCIe 3.0 x8 interface, the adapter provides ample bandwidth to fully support the aggregate throughput of its two 25Gb/s ports. This ensures that the network interface does not become a bottleneck for data-intensive applications. The adapter also features advanced offload engines designed to reduce the burden on the host CPU, including TCP/UDP/IP checksum offloads and potentially other protocol-specific optimizations, leading to improved overall system efficiency and application performance. With its high speed, low latency, and advanced features, the QL41212HLCU-CK is a critical component for next-generation data centers and high-performance computing clusters. It enables faster data processing, quicker access to storage, and more efficient communication between compute nodes, driving innovation in fields requiring massive data throughput and rapid analysis.
