ST7219 Quad-Port 10G SFP+ Ethernet Network Card, Intel X710-BM1 Controller PCIe 3.0 X8 10GbE SFP+ NIC Adapter, Compatible with Windows 11/10, Windows Server, Linux, VMware ESXi (Not Support macOS)

ST7219 is a four-port 10GbE SFP+ enterprise network adapter built around mature Intel X710-BM1 controller chip, benchmarked against official Intel X710-DA4 specs for data center networking upgrade. Equipped with four open SFP+ slots for free collocation of multimode/single-mode optical transceivers, direct attach copper DAC or active optical AOC cables to realize diversified long/short-distance network deployment, each port supports auto-negotiation between 10Gbps and 1Gbps transmission speed. Designed with standard PCIe3.0 X8 8.0GT/s interface to supply sufficient aggregated bandwidth for storage pooling, virtual machine cluster aggregation and soft router multi-WAN expansionIntel. Integrated comprehensive hardware acceleration including TCP/UDP checksum offload, overlay network offload and SR-IOV virtualization splitting to optimize virtualized environment transmission efficiency and cut system resource occupancy. Equipped with matched full-size and half-height brackets to fit standard full-tower chassis and slim rack server case, passive large-area heatsink ensures stable heat dissipation within 0~55 working temperature range. Fully driver validated for Windows 11/10, all generations Windows Server, mainstream Linux distros and VMware ESXi virtualization platform; explicitly no official driver support for macOS systems. Ideal solution for enterprise server cluster, DIY high-capacity NAS storage link expansion, IDC cabinet aggregation and openwrt/ikuai soft routing multi-port high-speed networking construction.
