FAQs

Q: What optics or cables are required?
A: Use QSFP56 DAC/AOC or QSFP56 optical transceivers. Some QSFP28 modules may operate at reduced rates where supported by both ends.

Q: Will it work in a PCIe Gen3 slot?
A: Yes, it is backward compatible with PCIe Gen3/Gen2 at the slot’s maximum bandwidth.

Q: Can I break out a 100G port to multiple lower‑speed links?
A: Breakout to 2x50G or 4x25G is platform and cable dependent. Check server and switch support plus use the appropriate breakout DAC/AOC.

Q: Does it support RoCE v2?
A: Yes. Configure lossless Ethernet (PFC/DCB) on the network for best RDMA performance.

Q: Is VMware ESXi supported?
A: Yes, with the correct vendor driver and ESXi version. Consult the VMware HCL for your server platform.
