Product information

Description

The Intel Ethernet Network Adapter E810-CQDA1 is a fiber network adapter for internal use, offering up to 100000 Mbit/s data transfer via PCI Express host interface. It supports advanced data-center features such as iWARP/RDMA for low-latency fabric services, Intel® Data Direct I/O (DDIO) to improve I/O processing efficiency by allowing adapters to access processor cache directly, and virtualization enhancements including PCI-SIG SR-IOV, Flexible Port Partitioning (FPP) and Virtual Machine Device Queues (VMDq).

Advantages

The adapter reduces latency and increases I/O bandwidth through iWARP/RDMA and Intel DDIO, improving performance for data-intensive workloads. SR-IOV and FPP enable efficient sharing and partitioning of the physical port into multiple virtual functions for better Quality of Service. VMDq offloads VM switching tasks to hardware to lower host CPU overhead and improve throughput.

Suitable for

High-throughput data center servers
Virtualized environments requiring direct I/O to VMs
Low-latency storage and compute clusters using RDMA
Applications needing fiber connectivity and PCI Express host interface

Key specifications

Model: Intel E810-CQDA1
Maximum data transfer rate: 100000 Mbit/s
Connectivity technology: Wired (fiber)
Host interface: PCI Express
Supported technologies: iWARP/RDMA, Intel® DDIO, PCI-SIG SR-IOV, Flexible Port Partitioning (FPP), VMDq
Intended use: Internal network adapter

How to use

Install the adapter into an available PCI Express slot on a compatible server motherboard, connect the fiber link to the network, and install the appropriate Intel drivers and firmware. Configure network settings and enable virtualization features (SR-IOV, FPP, VMDq) and RDMA/iWARP in the operating system or hypervisor as required. Verify link speed and functionality using vendor-provided tools or OS network utilities.

Usage recommendations

Use this adapter in rack or blade servers with supported Intel platforms and up-to-date firmware. For RDMA and low-latency workloads, enable DDIO and ensure the system BIOS and OS drivers are configured for RDMA/iWARP and SR-IOV support. Use appropriate fiber transceivers and cabling certified for 100GbE operation.
