Product Description
The Dell 540-BBKI is a high-performance network adapter designed to provide 40 Gigabit Ethernet connectivity. This adapter utilizes a QSFP+ (Quad Small Form-factor Pluggable Plus) interface, which supports four lanes of 10Gb/s data transmission, aggregating to a total bandwidth of 40Gb/s. This makes it ideal for demanding network environments such as data centers, high-performance computing clusters, and enterprise networks where high throughput is essential. This network adapter connects to the host system, typically a server or workstation, via a PCIe (Peripheral Component Interconnect Express) slot. The specific PCIe generation (e.g., PCIe 3.0 or 4.0) and lane configuration (e.g., x8 or x16) will determine its maximum potential throughput. The 40GBase-X standard indicates its adherence to the IEEE 802.3ba standard for 40 Gigabit Ethernet over various media, often fiber optics using QSFP+ modules. Beyond raw speed, adapters like the 540-BBKI often incorporate advanced features to enhance network performance and efficiency. These can include technologies like RDMA over Converged Ethernet (RoCE) for low-latency data transfers, Single Root I/O Virtualization (SR-IOV) for improved virtual machine performance, and various offload engines to reduce CPU utilization. These capabilities are crucial for modern virtualized and software-defined networking infrastructures.
