FAQs

Q: Does it require a PCIe Gen5 slot?
A: It performs best with Gen5 x16 but operates in Gen4/Gen3 at reduced bandwidth.

Q: Are transceivers included?
A: No. Optics and cables are sold separately.

Q: Can I switch between Ethernet and InfiniBand?
A: Yes. VPI allows mode selection via firmware/driver.

Q: Is GPUDirect RDMA supported?
A: Yes, with compatible GPUs, platform, and software stack.
