SMUGDESK Dual Port 10G SFP+ PCIe 2.0 x8 CNA Network Card

Dual 10G SFP+ Converged Adapter

The SMUGDESK dual-port 10G SFP+ PCIe 2.0 x8 CNA card adds converged Ethernet and storage networking to compatible H3C UniServer G3 rack models including the R4700G3, R4900G3, R2700G3 and R2900G3. It replaces the original UN-CNA-10GE-2P-560F-B2-1-X part and fits both low-profile and full-height chassis with the included brackets. This adapter targets administrators who need hardware offload for iSCSI and FCoE traffic in virtualization clusters.

Sustained 24/7 thermal stability

A passive aluminum heatsink dissipates heat without moving parts, enabling continuous nonstop operation in dense server racks. The PCIe 2.0 x8 interface maintains consistent throughput for storage convergence workloads such as SAN expansion and virtualization host networking. CPU overhead stays reduced through hardware checksum, TSO offload, SR-IOV and VMDq during prolonged high-utilization periods.

PCIe 2.0 x8 bandwidth ceiling

The eight-lane generation 2.0 bus caps maximum aggregate throughput below the theoretical dual 10G line rate, so sustained simultaneous full-duplex traffic on both ports can saturate the host interface. Jumbo frames up to 9000 bytes and 802.1Q VLAN tagging operate within this constraint. Buyers needing higher host bandwidth for dual 10G line-rate performance should consider a PCIe 3.0 or newer platform.
