## Summary description

The Intel Ethernet Network Adapter E810-CQDA2 offers high-speed connectivity with a maximum data transfer rate of 100000 Mbit/s. Designed for internal use, it utilizes PCI Express for efficient communication. The fiber interface ensures reliable and fast data transmission, making it ideal for demanding network environments.

## Long description

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
Key specifications
Manufacturer: Intel
Model: E810-CQDA2 (MPN: E810CQDA2BLK)
Interface: Fiber
Host interface: PCI Express
Maximum data transfer rate: 100000 Mbit/s
Technologies: iWARP/RDMA, Intel DDIO, SR-IOV, Flexible Port Partitioning, VMDq
Intended use: Internal server network adapter
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.
Usage 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.
