Dual-Port 10Gb SFP+ Adapter

This C&N network card adds two 10 Gigabit Ethernet ports to a server or workstation through a PCI Express 3.0 x8 slot. It uses the Mellanox ConnectX-3 controller and targets administrators who need high-throughput links for clustered databases, web infrastructure or high-frequency trading workloads.

Low-Profile PCIe 3.0 x8 Integration

The adapter fits a low-profile bracket and requires a PCIe 3.0 x8 or higher slot, remaining compatible with PCIe 2.0 and 1.1. It supports FreeBSD, Linux 5.x, VMware 5.5-6.7, Windows 7-10 and Windows Server 2008-2019, plus Legacy and UEFI PXE boot for diskless deployments.

Sustained Throughput with CPU Offload

Stateless TCP, UDP and IP offload reduces host CPU load during continuous traffic, while RDMA over Ethernet delivers latency as low as 1 µs in both bare-metal and SR-IOV virtualised environments. The card supports up to 127 virtual functions, allowing dense multi-tenant deployments without saturating the processor.
