Frequently Asked Questions
What are the primary interface capabilities of the Intel E810-CQDA2? +
The Intel Ethernet Network Adapter E810-CQDA2 features a dual-port configuration utilizing QSFP28 connectors. It is designed for high-speed connectivity, supporting 100GbE speeds per port. This adapter interfaces with the host system via a PCIe 4.0 x16 slot, providing the necessary bandwidth to handle intensive data center workloads and high-throughput networking environments.
Does the Intel E810-CQDA2 support RDMA for low-latency applications? +
Yes, this adapter supports Remote Direct Memory Access (RDMA) through both iWARP and RoCE v2 protocols. These features are critical for reducing CPU overhead and achieving ultra-low latency in clustered computing and storage area networks, making the E810-CQDA2 an excellent choice for modern cloud-native and high-performance computing infrastructures.
Is the Intel E810-CQDA2 compatible with standard server PCIe slots? +
This adapter requires a PCIe 4.0 x16 physical slot for optimal performance. While it is generally backward compatible with PCIe 3.0 slots, please note that using an older generation slot will significantly restrict the throughput capacity. Ensure your server chassis supports the physical length and power requirements of this card before deployment.
What management features are included with the Intel E810-CQDA2? +
The card supports advanced management through the Intel Ethernet Controller E810, featuring platform-level manageability tools. It includes support for NC-SI (Network Controller Sideband Interface) and MCTP (Management Component Transport Protocol) to enable remote management through the Baseboard Management Controller (BMC), ensuring seamless integration into enterprise-grade remote monitoring systems.
What type of optical transceivers or cables should be used with this NIC? +
The E810-CQDA2 uses QSFP28 ports, which accommodate a variety of 100GbE optical transceivers and Direct Attach Copper (DAC) cables. You should select modules that match your fiber plant—typically multi-mode or single-mode fiber—or use active optical cables (AOCs) for shorter reach requirements within the rack. Always ensure your chosen optics are compatible with the Intel E810 architecture.
How does the Intel E810-CQDA2 handle packet processing for virtualization? +
This adapter utilizes Application Device Queues (ADQ) technology to provide predictable performance and optimized packet processing. By prioritizing critical traffic and reducing jitter, it effectively manages multi-tenant workloads in virtualized environments, ensuring that virtual machines and containers maintain consistent throughput even during peak network utilization periods.
What are the power requirements for installing this network adapter? +
The E810-CQDA2 is a high-performance adapter, so it is important to confirm that your server's PCIe slot can provide the necessary power. Refer to the hardware documentation for your specific server model to ensure the thermal and electrical specifications are met, as high-speed 100GbE cards require sufficient cooling and power draw to operate reliably under full load.
Can the E810-CQDA2 be used in storage-heavy environments? +
Absolutely. This NIC is highly optimized for NVMe over Fabrics (NVMe-oF) deployments. By leveraging its advanced hardware offload capabilities, the adapter accelerates storage traffic, allowing for faster access to remote NVMe storage arrays. This makes it a preferred solution for data centers transitioning to high-speed, all-flash storage architectures.
