Product Description
The Dell 540-BDDS network adapter, powered by the Intel E810-CQDA2 controller, represents the pinnacle of network connectivity with its dual 100 Gigabit Ethernet (100GbE) ports. These ports utilize QSFP28 connectors, which are standard for 100GbE interfaces, allowing for the use of various high-speed optical transceivers and Direct Attach Copper (DAC) cables. The adapter connects to the host system via a high-bandwidth PCIe Gen 4.0 x16 interface, ensuring that the full potential of the 100GbE links can be realized without introducing bottlenecks, making it suitable for the most demanding data center applications. This adapter is engineered for environments that require extreme data throughput and low latency, such as artificial intelligence (AI) and machine learning (ML) clusters, high-performance computing (HPC) environments, high-speed storage networks (e.g., NVMe-oF), and large-scale cloud infrastructure. The Intel E810 chipset offers a rich set of advanced features, including support for RDMA over Converged Ethernet version 2 (RoCE v2) and iWARP (Internet Wide Area RDMA Protocol), which offload network processing from the CPU and significantly reduce latency. It also provides robust support for Data Plane Development Kit (DPDK) applications, network virtualization (NVGRE, VXLAN), and Quality of Service (QoS) features. Designed for integration into Dell servers and other compatible systems, the 540-BDDS ensures high reliability and performance. It typically includes a low-profile bracket, offering flexibility for installation in various server chassis types. This adapter is a critical component for organizations looking to build or upgrade their network infrastructure to support the massive data flows characteristic of modern high-performance computing and data-intensive workloads.
