Dell Qlogic Fastlinq QL41262 2x 10/25GbE SFP28 PCIe x8 LAN Network Controller 0415DX 051GRM

QLogic® FastLinQ QL41262HFCU-DE and QL41262HLCU-DE 10/25GbE Converged Network Adapters (CNAs) with Universal Remote Direct Memory Access (RDMA) leverage QLogic’s eighth-generation technology to deliver true 25Gb per second (25Gbps) Ethernet performance.
Integrated, advanced networking with simultaneous LAN (TCP/IP) and SAN (Fibre Channel over Ethernet [FCoE] and iSCSI) traffic eliminates I/O bottlenecks and conserves CPU cycles.
Optimized for use across enterprises, managed service providers (MSPs), and large public and scalable public cloud deployments, the QL41262 enables organizations to achieve new levels of performance in physical, virtual, and cloud environments.
