Description

High-density 25GbE OCP 3.0 NIC with four SFP28 ports for modern virtualized and cloud workloads. Delivers advanced offloads (SR-IOV, VXLAN/Geneve) and precise timing (PTP 1588v2) for low-latency performance, with wide OS and hypervisor support. Ideal for scale-out servers needing maximum 25G port density in an OCP 3.0 slot.

Features

- Four 25G-ready SFP28 ports in an OCP 3.0 footprint
- PCIe 4.0 bandwidth for consistent low latency
- Comprehensive virtualization with SR-IOV and overlay offloads
- RoCEv2 support for efficient RDMA-based fabrics
- PTP 1588v2 hardware timestamping for time-sensitive networks

FAQs

Q: Does this adapter include SFP28 transceivers or DAC cables?
A: No. Optics and cables are sold separately; use 10G SFP+ or 25G SFP28 modules/DACs as required.

Q: Is it compatible with OCP 3.0 slots in mainstream rack servers?
A: Yes. It is designed for OCP NIC 3.0 slots; verify mechanical type and server QuickSpecs for fit.

Q: Can I run mixed speeds across the ports?
A: Yes, ports can operate independently at 10G or 25G subject to switch and optic/DAC capabilities.

Q: Does it support hardware timestamping and PTP?
A: Yes, IEEE 1588v2 PTP hardware timestamping is supported.
