Description

Dual‑port 10GbE OCP 3.0 mezzanine adapter built for high‑density, power‑efficient server I/O. Two SFP+ ports support 10G optics and DACs, while SR‑IOV and advanced offloads boost virtualization and overlay network performance. Ideal for cloud, NFV, and software‑defined infrastructures in servers with an OCP 3.0 slot.

Features

- Dual 10GbE SFP+ for high-throughput, low-latency server networking
- OCP 3.0 mezzanine design saves PCIe slots and simplifies cabling
- SR-IOV and advanced queuing for efficient VM density
- Overlay offloads (VXLAN/NVGRE) for modern SDN fabrics
- DCB/QoS features for converged and latency-sensitive traffic
- PXE and iSCSI boot support for stateless provisioning

FAQs

Q: Does this NIC support 1Gb operation?
A: Yes, with supported 1Gb SFP modules it can negotiate 1GbE where permitted by firmware/driver.

Q: Can I use SFP28 modules?
A: No. Use 10G SFP+ optics or 10G DAC/AOC cables.

Q: What’s the difference between this OCP 3.0 card and a PCIe adapter?
A: OCP 3.0 is a mezzanine form factor that plugs into a dedicated OCP slot, freeing PCIe slots and integrating I/O closely with the server.

Q: Is SR-IOV supported for virtualization?
A: Yes. SR-IOV is supported; verify enablement in BIOS/UEFI and hypervisor settings.
