Intel Ethernet Network Adapter E835-CCQDA1 - Network Adapter - PCIe 4.0 x16 / PCIe 5.0 x8 - 200 Gigabit QSFP28 x 1 - Single Pack

The Intel Ethernet Network Adapter E835-CCQDA1 is a high-performance 200 Gigabit Ethernet network adapter designed for demanding data center and enterprise environments. Featuring a single QSFP-DD port and supporting PCI Express 5.0 x8 (backward compatible with PCIe 4.0 x16), this adapter delivers exceptional throughput and low latency for bandwidth-intensive applications such as AI, machine learning, high-performance computing, and large-scale virtualization.

Advantages

Unmatched 200 GbE performance with advanced features like iWARP RDMA, RoCEv2, SR-IOV, and ADQ (Application Device Queues) ensures efficient data processing and reduced CPU overhead. The adapter supports both low-profile and full-height brackets for flexible deployment in various server form factors. Energy Efficient Ethernet (EEE) and Time Sync (PTP) enhance power efficiency and network synchronization.
