FAQs

Q: What does no‑crypto mean for this NIC?
A: It indicates hardware encryption features (e.g., inline IPsec/TLS offload) are disabled. All other networking and performance features remain available.

Q: Are QSFP56 DAC/AOC cables supported?
A: Yes. Use QSFP56 passive/active DAC or AOC for 100G links; verify cable length and compatibility with your switch.

Q: Is PCIe 3.0 supported?
A: Yes. The card operates in PCIe 3.0 slots with proportionally lower host bandwidth.

Q: Does it support SR‑IOV and RDMA?
A: Yes. SR‑IOV and RoCEv2 RDMA are supported with appropriate drivers and OS configuration.

Q: Can it use QSFP28 100G optics?
A: Many deployments use QSFP28 100G optics; confirm firmware/module compatibility for your devices.
