Dual-port 100GbE QSFP28 adapter for PCIe 4.0 x16

The Intel E810-2CQDA2 provides two QSFP28 ports each running at 100, 50, 25 or 10GbE. It targets communications, cloud and storage deployments that need up to 200Gbps aggregate bandwidth in a single bifurcated slot. Application Device Queues and Dynamic Device Personalization steer traffic and accelerate packet classification for predictable response times. Both RDMA iWARP and RoCEv2 are supported for low-latency storage and HPC connectivity.

Sustained throughput with bifurcation enabled

Full 200Gbps performance requires PCIe 4.0 x16 slot bifurcation configured in the system BIOS. Without bifurcation the adapter cannot expose both ports at line rate, so sustained cloud and storage workloads depend on platform support. ADQ isolates critical queues to maintain consistent latency under continuous load. DDP profiles can triple throughput for specific packet-processing pipelines during prolonged operation.

Thermals noise and power in normal use

The supplier data does not disclose thermal design power, fan presence or acoustic figures for this adapter. Power draw and cooling requirements will vary with the host chassis airflow and the optical or direct-attach cables installed. Operators should validate thermal margins in their specific server platform before deployment.

Questions about this item

How much power does the E810-2CQDA2 draw when both QSFP28 ports run at 100GbE all day?

The adapter delivers up to 200Gbps total throughput over a PCIe 4.0 x16 slot; actual power draw depends on the host system and attached modules.

What must the host system provide for the card to reach its full 200Gbps capability?

A PCIe 4.0 x16 slot with bifurcation enabled in the BIOS is required for full 200Gbps performance.

Will the adapter work in an older server that only has PCIe 3.0 slots?

The card uses a PCIe 4.0 x16 interface; it will negotiate down to the slot speed available, but total bandwidth will be limited by the slower generation.
