Product information

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

Key specifications

  • Brand: INTEL
  • Model: E810-CQDA2 (MPN: E810CQDA2)
  • Maximum data transfer rate: 100000 Mbit/s
  • Interface: Fiber
  • Host interface: PCI Express
  • Technologies: iWARP/RDMA, Intel® DDIO, PCI-SIG SR-IOV, Flexible Port Partitioning, VMDq
  • EAN: 0735858430142

How to use

Install the adapter into an available PCI Express slot in a compatible server following the server and adapter installation guides. Connect fiber optic cables to the adapter ports and configure link settings in the operating system or firmware. Enable and configure RDMA, SR-IOV, FPP or VMDq features as required by the workload and the host OS or hypervisor. Ensure drivers and firmware provided by Intel are installed and up to date for optimal performance and stability.

Usage recommendations

Use this adapter in systems with compatible PCI Express slots and fiber connectivity; keep Intel drivers and firmware current, and validate RDMA and virtualization feature compatibility with your OS/hypervisor to achieve expected low-latency and high-throughput performance.
