Description
The AddOn ADD-PCIE4-2QSFP28 is a high-performance 100-Gigabit Ethernet PCIe 4.0 x16 network interface card designed to deliver exceptional throughput, scalability, and flexibility for next-generation data centers and enterprise networks. Powered by the Intel® E810 chipset, this dual-port NIC supports two open QSFP28 interfaces, enabling compatibility with a wide range of transceivers for both multi-mode (MMF) and single-mode (SMF) fiber deployments.
Engineered for demanding virtualization, cloud computing, and high-performance computing environments, this NIC supports iWARP and RoCEv2 RDMA, Intel® Ethernet AVF, and advanced virtualization technologies including SR-IOV, VxLAN, GENEVE, and GRE. With support for IEEE 1588 PTP v1 & v2, per-packet time stamping, and high-level VLAN filtering, it ensures precise synchronization and efficient traffic handling.
Built for reliability and interoperability, the ADD-PCIE4-2QSFP28 is 100% compliant with IEEE 802.3 standards, tested for multi-OS support including Windows, Linux, VMware ESXi, and is supplied with both half-height and full-height brackets for easy deployment in diverse server platforms.
