Intel PCIe 4.0 x16 QSFP28 x 2 Ethernet Network Adapter

The Intel E810CQDA2BLK is a PCIe 4.0 network adapter that equips a server with two QSFP28 100 Gb Ethernet ports. It is designed for administrators who need dependable bandwidth and low latency in data centers, cloud platforms, and AI or storage clusters.

This adapter connects through a PCIe 4.0 x16 slot, giving each port the throughput required for applications that move large volumes of data. When tasks such as distributed machine learning, real time analytics, or high performance storage replication demand quick exchanges between nodes, the card keeps pace without becoming a bottleneck.

Support for RDMA over both iWARP and RoCEv2 allows the adapter to bypass the host CPU during transfers, cutting latency and freeing processor cycles for the workload itself. Application Device Queues help sensitive applications receive consistent response times, while Dynamic Device Personalization fine-tunes packet processing to match network functions virtualization, 5G, or similar service chains.

For environments that rely on precise event timing, the card supports IEEE 1588 PTP v2. Enhanced DPDK compatibility raises packet throughput for custom data plane applications, and EPCT port configuration options let administrators tailor link behavior to match changing network needs. The package also includes a low profile bracket, making it easy to fit in compact or full-height server chassis.

Because it combines high line-rate performance with flexible acceleration features, the Intel E810CQDA2BLK suits enterprises building hybrid clouds, telecom operators rolling out edge services, and research labs pushing large data sets across clustered storage.
