Frequently Asked Questions

What is Intel ADQ and why does it matter?

Application Device Queues (ADQ) dedicates hardware queues to specific applications, reducing latency and improving throughput consistency for latency-sensitive workloads.

Is PCIe 4.0 required for full performance?

PCIe 4.0 x16 is recommended for full quad-port 25GbE throughput. The card is backward compatible with PCIe 3.0 slots at reduced aggregate bandwidth.

Does it support RDMA?

Yes — the E810-XXVDA4 supports RoCEv2 (RDMA over Converged Ethernet) for low-latency storage and HPC networking.
