## Summary description

The Intel Ethernet Network Adapter E810-CQDA2 provides high-speed wired connectivity with a maximum data transfer rate of 100000 Mbit/s. Designed for internal use, it features a PCI Express host interface and fiber connectivity, making it ideal for demanding network environments that require reliable and fast data transmission.

## Long description

The Intel Ethernet Network Adapter E810-CQDA2 is a PCI Express fiber network card that delivers up to 100000 Mbit/s wired connectivity for data center and server environments. It supports iWARP/RDMA for low-latency Remote Direct Memory Access over Ethernet and includes Intel® Data Direct I/O (DDIO) to optimize I/O data processing by allowing adapters and controllers to interact directly with processor cache. The adapter is built for high-throughput, low-latency use cases and integrates with virtualization technologies such as PCI-SIG SR-IOV, Flexible Port Partitioning and Virtual Machine Device Queues (VMDq).
Advantages
The E810-CQDA2 reduces latency and increases I/O bandwidth through iWARP/RDMA capabilities and Intel DDIO, while also improving power efficiency by minimizing memory detours. Hardware support for SR-IOV, Flexible Port Partitioning and VMDq enables efficient sharing of the physical port among multiple virtual functions and reduces hypervisor switching overhead, improving overall throughput in virtualized environments.
Suitable for
 High-performance servers and data centers requiring up to 100000 Mbit/s fiber connectivity
 Low-latency applications and RDMA-based workloads
 Virtualized environments using SR-IOV, Flexible Port Partitioning or VMDq
 Compute nodes and storage servers needing high I/O bandwidth
