200GbE, Intel® Ethernet 800 Series E835 network adapters support the growing bandwidth demands of modern networks, especially for cloud services, virtualized environments, and large data transfers.

The low-power design reduces energy consumption across the system lowering costs and environmental impact, while addressing increasingly important power density challenges.

Concurrent support for iWARP and RoCEv2 RDMA, modern security features, key timing protocols, and fast data exchange, make 200GbE E835 network adapters an optimal choice for critical applications. These standards-based adapters deliver performance without the complexity and high cost of proprietary technologies.

Deployment is made easier through shared drivers for all 800 Series Network Adapter families (E835, E830 and E810), ensuring software consistency across generations of products.

These 200GbE adapters also offer multiple port configurations, providing relief for port-constrained networks using the available Ethernet Port Configuration Tool (EPCT).

Optimized for Intel® Xeon® processors

Data centers and workloads need computing capacity and powerful ways to move data securely. Intel® architecture offers both. Deployment-ready, reliable, and affordable, Intel Ethernet E835 Network Adapters are the perfect choice for amplifying server performance with Intel® Xeon® 6 processors.
