Description

Quad-port 25GbE SFP28 PCIe adapter designed for high-density connectivity and consolidation. Powered by Intel E810 silicon, it delivers four independent 25G/10G ports with robust virtualization features, overlay offloads, and precise time synchronization via IEEE 1588 PTP. Ideal for multi-tenant hosts, NFV, and spine/leaf edge connectivity where port count and performance are critical.

Features

- Four 25/10GbE SFP28 ports for high-density server connectivity
- PCIe Gen4 host interface for ample throughput headroom
- SR-IOV and hardware offloads to accelerate virtualized environments
- Overlay tunneling offloads (VXLAN/Geneve/NVGRE) for SDN fabrics

FAQs

Q: Can I use different speeds across the four ports?
A: Yes. Each port can operate independently at 25G or 10G based on the optics/cables and switch configuration.

Q: Is this suitable for virtualization and NFV?
A: Yes. The adapter supports SR-IOV and advanced offloads ideal for virtualized and NFV workloads.

Q: Does it work with ESXi, Windows Server, and Linux?
A: Yes, with the appropriate Intel E810 family drivers for each OS.

Q: Are optics included?
A: No. Use compatible SFP28 or SFP+ optics or DAC/AOC cables purchased separately.

Q: Is it compatible with existing 10G infrastructure?
A: Yes. It operates at 10GbE with SFP+ modules and matching switch configuration.
