The DN-10190 Dual-Port 40G QSFP adapter with PCIe 3.0 and Mellanox Connectx-3 technology features two 40G QSFP+ Ethernet ports and two QSFP ports supporting FDR-14 InfiniBand or 40Gb Ethernet. It is compatible with various operating systems and offers numerous features such as RDMA, TCP/UDP/IP Off-Load, SR-IOV support, and traffic steering.

- Two 40 Gigabit QSFP+ Ethernet ports
- PCI-Express host interface specification v3.0 x8 and Complete with PCIe2.0 and 1.1
- Compliant with QSFP+ MSA Spec Rev 1.0
- Support for InfiniBand FDR speeds of up to 56Gbps (auto-negotiation FDR-10, DDR and SDR)
- Low-profile form factor adapter with 2u bracket

The DN-10190 Dual-Port 40G QSFP adapter with PCI Express 3.0 and x8 Mellanox Connectx-3 technic delivers high-bandwidth and industry-leading Ethernet connectivity, and is compliant with PCIe2.0 and 1.1. It features two 40 Gigabit QSFP+ Ethernet ports compliant with QSFP+ MSA Spec Rev 1.0, and two QSFP ports supporting FDR-14 InfiniBand or 40Gb Ethernet, with support for InfiniBand FDR speeds of up to 56Gbps (auto-negotiation FDR-10, DDR and SDR). The low-profile form factor adapter with 2u bracket supports virtual protocol interconnect (VPI), InfiniBand Architecture specification v1.2.1, IEEE Std. 802.3, copper cables and optical cables with the use of QSFP connectors, and SFP+ cables available through QSA (Quad to Serial). It enables low latency RDMA over 40Gb Ethernet, with legacy and UEFI PXE network boot support, and supports iSCSI as a software iSCSI initiator in NIC mode with NIC driver. The adapter supports multiple operating systems, such as FreeBSD, Linux 5.x and above, VMware, Windows server2008/2012/2016/2019, win7/win8/win8.1/win10 32 or 64bit. It also supports CORE-Direct○,R application off-load, GPUDirect application off-load, RDMA over converged Ethernet (RoCE), end-to-end QoS and congestion control, TCP/UDP/IP stateless off-load, Ethernet encapsulation (EoIB), SR-IOV support (16 virtual functions supported by KVM and Hyper-V(OS dependant) up to a maximum 127 virtual functions supported by the adapter), and traffic steering across multiple cores, making it a versatile adapter suitable for a wide range of applications.
