## Summary description

The Intel Ethernet Network Adapter E810-CQDA2 offers a maximum data transfer rate of 100000 Mbit/s. It features a PCI Express host interface and fiber connectivity technology, making it ideal for high-performance networking applications.

## Long description

The Intel Ethernet Network Adapter E810-CQDA2 is a high-performance networking solution designed to meet the demanding requirements of modern data centers and enterprise environments. With a maximum data transfer rate of 100,000 Mbit/s, this adapter provides the extreme bandwidth necessary for data-intensive applications, cloud computing, and high-speed storage networking. Utilizing fiber connectivity technology and a PCI Express host interface, it ensures reliable and efficient data transmission across your network infrastructure.
Advantages
This network adapter leverages advanced technologies such as iWARP and RDMA to deliver low-latency fabric services, significantly improving communication efficiency. The integration of Intel Data Direct I/O Technology allows the adapter to communicate directly with the processor cache, bypassing system memory to reduce latency and power consumption. Furthermore, the inclusion of PCI-SIG SR-IOV and Flexible Port Partitioning enables efficient virtualization, allowing a single physical port to be divided into multiple virtual devices with guaranteed quality of service. Virtual Machine Device Queues further enhance performance by offloading switching tasks from the virtual machine monitor to the hardware, resulting in higher throughput and reduced system overhead.
Suitable for
High-performance data center networking
Cloud computing and virtualization environments
High-speed storage area networks
Enterprise-level server infrastructure
This adapter may not be suitable for standard home office setups or small business environments that do not require 100 Gbps speeds or fiber-optic infrastructure. It is specifically engineered for professional server-grade hardware and may not be compatible with consumer-grade desktop motherboards or operating systems that lack the necessary driver support for high-end enterprise networking controllers.
Key specifications
Data transfer rate: 100,000 Mbit/s
Connectivity: Fiber
Host interface: PCI Express
Technology: Wired
Virtualization support: SR-IOV, VMDq, Flexible Port Partitioning
Acceleration: iWARP/RDMA, Intel Data Direct I/O
How to use
To install the Intel Ethernet Network Adapter E810-CQDA2, ensure your server is powered down and disconnected from the power source. Insert the adapter into an available, compatible PCI Express slot on your server motherboard. Secure the bracket to the chassis to ensure stability. Once installed, connect the appropriate fiber-optic cables to the ports. After booting the system, install the latest drivers provided by Intel to ensure full functionality and optimal performance of the virtualization and acceleration features.
What to consider before purchase
Verify that your server motherboard has an available PCI Express slot with sufficient lanes to support the adapter.
Ensure your network infrastructure supports fiber-optic connections at 100 Gbps speeds.
Check for compatibility with your server operating system and virtualization platform.
Confirm that your power supply unit can handle the additional load of high-performance networking hardware.
Usage recommendations
For optimal performance, ensure that your server BIOS and operating system drivers are updated to the latest versions. Configure SR-IOV and VMDq settings within your virtualization management software to fully utilize the hardware offloading capabilities provided by the adapter.
