Network adapter HP HPE Intel E810-CQDA2 2-port QSFP28 100Gb PCI Express, Ethernet/Fiber, wired

HPE Intel E810-CQDA2 is a wired two-port QSFP28 network adapter designed for installation in server PCI Express slots. The adapter provides Ethernet and fiber connectivity over QSFP28 ports and is intended for high‑speed links up to 100 Gb, supporting data center networking, virtualization and high‑bandwidth storage or compute interconnects. The card is an internal component for servers and has a compact form factor with a listed weight of about 0.33 kg.

Advantages

The adapter delivers dual QSFP28 ports for consolidated 100 Gb connectivity through a PCI Express host interface, enabling high throughput and low-latency links for demanding server environments. With support for both Ethernet and fiber connections, the card offers flexibility in cabling and network design while maintaining compatibility with standard server PCIe slots. Its wired connectivity and server-oriented design make it suitable for use in data centers where reliability and predictable performance are required.

Suitable for

• High‑bandwidth server-to-switch connections in data centers
• Virtualization hosts requiring high throughput for multiple VMs
• Storage networks and cluster interconnects with heavy data transfer
• Compute nodes needing low-latency, high-speed networking

Key specifications

• Connectivity technology: Wired
• Interface: Ethernet / Fiber via QSFP28 ports
• Host interface: PCI Express
• Maximum data transfer rate: up to 100 Gb
• Form factor: internal server adapter
• Approximate weight: 0.33 kg

How to use

Install the adapter into an available PCI Express slot on a compatible server following the server manufacturer’s installation guidelines. Connect QSFP28 optical or DAC cables to the QSFP28 ports to establish Ethernet or fiber links. Configure network settings and firmware or driver installation according to HPE and Intel instructions to ensure proper recognition by the operating system and management software. Verify link status and perform any required network configuration such as VLANs, MTU size, or teaming as appropriate for the deployment.

Recommendations

Use qualified QSFP28 optical transceivers or direct attach cables rated for 100 Gb to ensure signal integrity. Keep firmware and drivers up to date and follow server airflow and mounting guidelines to maintain thermal performance in the rack environment.
