FAQs

Q: Can I use SFP+ modules for 10GbE?
A: Yes, many adapters support 10G operation with compatible SFP+ modules or DACs. Verify transceiver compatibility for your specific model.

Q: Does it require a PCIe x8 slot?
A: It needs x8 electrical lanes. It can be installed in x8 or x16 physical slots that provide at least x8 lanes.

Q: Are passive DAC cables supported?
A: Yes, within supported lengths and with compatible switch ports. Check the cable length limits for 25G operation.

Q: Do I need PFC for RoCE v2?
A: For best RDMA performance, enable lossless Ethernet (DCB with PFC) end‑to‑end.

Q: Are vendor‑locked optics required?
A: Use standards‑based SFP28 optics/DACs supported by both the NIC and connected switch; check your environment’s compatibility policy.
