Dell 85F8F E810-CQDA2 2-Ports 100GbE QSFP28 PCIe Adapter

Product Description

The Dell 85F8F, identified as the E810-CQDA2, is a cutting-edge 100 Gigabit Ethernet (100GbE) Network Interface Card (NIC) designed to meet the extreme bandwidth and low-latency demands of modern data centers and high-performance computing (HPC) environments. Equipped with two QSFP28 ports, each capable of operating at 100Gbps, this adapter provides massive aggregate throughput, making it suitable for the most data-intensive applications. The adapter utilizes the PCIe Gen3 x16 interface, ensuring sufficient bandwidth between the NIC and the host system to avoid bottlenecks. A key feature of the 85F8F is its support for RoCE (RDMA over Converged Ethernet), which enables Remote Direct Memory Access. RDMA allows applications to access memory on remote systems directly without involving the operating system kernel, significantly reducing latency and CPU overhead. This is crucial for applications like distributed storage, high-frequency trading, and large-scale data analytics where every microsecond counts. The adapter also includes hardware offloads for TCP/UDP/IP processing, further freeing up the host CPU for application tasks. Designed for scalability and efficiency, the Dell 85F8F supports virtualization technologies such as Single Root I/O Virtualization (SR-IOV), which allows multiple virtual machines to share the physical NIC with dedicated resources, improving performance and isolation. Its robust feature set, including high throughput, low latency, and RDMA capabilities, makes it an ideal choice for demanding workloads such as artificial intelligence (AI), machine learning (ML), big data analytics, and high-performance storage solutions.
