Description
The Dell R3F0N is a powerful dual-port network adapter engineered to meet the extreme bandwidth requirements of modern data centers and high-performance computing (HPC) clusters. Each of its two QSFP+ ports offers a staggering 40 Gigabit per second (Gb/s) connection, providing a total aggregate bandwidth of 80 Gb/s. This makes it exceptionally well-suited for applications that demand rapid data movement, such as large-scale data analysis, high-frequency trading, and high-performance storage networking. Installed via a PCIe 3.0 x8 interface, the R3F0N ensures that the network adapter can communicate with the server's CPU and memory at speeds commensurate with its high-speed ports. The PCIe 3.0 standard offers a bandwidth of approximately 7.88 GB/s per lane, and with eight lanes, it provides ample throughput for the 40Gb/s connections. This high-speed interface minimizes latency and maximizes data transfer efficiency. The card supports 40GBase-X Ethernet, which typically utilizes QSFP+ transceivers and can connect via optical fiber or direct-attach copper cables depending on the distance and specific transceiver used. The dual-port design offers redundancy and increased throughput capabilities, allowing for link aggregation or connection to multiple network segments. The Dell R3F0N is a critical component for building high-speed, low-latency network infrastructures.
