Network Adapter Intel E810-CQDA2 Fiber 100000 Mbit/s

The Intel Ethernet Network Adapter E810-CQDA2 is a high-performance fiber network card for internal server use, offering up to 100000 Mbit/s over a PCI Express interface. It supports modern data-center features such as RDMA over Converged Ethernet (iWARP) and Intel Data Direct I/O Technology (DDIO) to reduce latency and improve I/O efficiency.

Advantages

This adapter provides low-latency data transfer through iWARP/RDMA with Kernel Bypass, Direct Data Placement and Transport Acceleration. Intel DDIO enables direct communication between the adapter and processor cache to lower latency and increase I/O bandwidth. Hardware virtualization features including PCI-SIG SR-IOV, Flexible Port Partitioning (FPP) and Virtual Machine Device Queues (VMDq) allow the single fiber port to be partitioned into virtual functions for better resource sharing and reduced VMM switching overhead.

Suitable for

• High-throughput server networking in data centers
• Virtualized environments requiring SR-IOV or FPP
• Workloads needing low-latency I/O such as RDMA-enabled applications
• PCI Express based internal server installations with fiber connectivity

How to use

Install the E810-CQDA2 into an available PCI Express slot in a compatible server following the server and adapter manufacturer instructions. Connect fiber cabling to the adapter's fiber interface and configure network settings in the operating system or hypervisor. Enable supported features (for example RDMA, SR-IOV or FPP) in firmware and OS/hypervisor drivers as required for your workload.

Recommendations

Use vendor-provided drivers and firmware updates to ensure compatibility and performance. For RDMA and DDIO benefits, verify platform support (CPU, chipset, BIOS/UEFI and OS) and test in your environment. When deploying virtualization features, allocate virtual functions and bandwidth policies according to workload requirements.
