Dell 540-BBRN XL710 2-Ports 40GbE QSFP+ PCIe Converged Adapter

Product Description

The Dell 540-BBRN, featuring the Intel XL710 controller, is a high-performance converged network adapter (CNA) designed to deliver exceptional throughput and low latency for demanding enterprise and data center environments. This adapter boasts dual 40 Gigabit Ethernet (40GbE) ports, utilizing QSFP+ (Quad Small Form-factor Pluggable Plus) connectors, which enable high-density networking and significant bandwidth aggregation. The 40GbE speed per port is crucial for applications such as high-performance computing (HPC), large-scale data storage, and demanding virtualization environments where rapid data movement is paramount. Integrated within the adapter is the Intel XL710 controller, a sophisticated chipset that provides advanced networking features and offloads. These features include RDMA over Converged Ethernet (RoCE), which allows for low-latency, high-throughput data transfers by bypassing the host CPU and kernel network stack, thereby improving application performance and efficiency. The adapter also supports various Ethernet standards and protocols, ensuring compatibility with a wide range of network infrastructure and providing flexibility in deployment. Connecting via a PCI Express (PCIe) interface, typically PCIe 3.0 x8 or higher, the Dell 540-BBRN ensures that the network adapter has sufficient bandwidth to operate at its full potential without introducing bottlenecks. This makes it an ideal choice for servers that require high-speed network connectivity to support intensive workloads, such as big data analytics, real-time financial trading, and large-scale cloud deployments. The converged nature of the adapter also allows it to handle both traditional Ethernet traffic and storage traffic over a single network, simplifying infrastructure and reducing costs.
