A: QSFP56 100G DAC/AOC and optical transceivers for 100GbE. Check module firmware compatibility for your environment.

Q: Will it work in a PCIe 3.0 slot?
A: Yes. It is backward compatible with PCIe 3.0, with reduced host bandwidth compared to PCIe 4.0.

Q: Does it support SR-IOV and RDMA?
A: Yes. SR‑IOV virtualization and RDMA over Converged Ethernet (RoCEv2) are supported when enabled in drivers/OS.

Q: Is it compatible with common server OSes?
A: Yes. Driver support is available for major Linux distributions and Windows Server; obtain drivers from the vendor.

Q: Can I use QSFP28 100G modules?
A: Many environments use 100G QSFP28 optics with these ports; verify switch/NIC firmware and module compatibility before deployment.
