Feature: 1. High Performance Network Adapter: The IPCIe network card is a PCIe to 2-port 2.5G Ethernet network adapter that supports speeds of up to 2500 Mbps. 2. Extensive System Compatibility: This network adapter supports multiple operating systems and platforms, including for Hackintosh, ESXI 6.7 (not compatible with 7.0), PVE, ikuai, unraid 6.9.2, and OpenWrt. It is plug-and-play for systems, while for Linux, TrueNAS/FreeNAS, certain versions of OpenWrt, and older versions of ikuai may require driver installation. 3. Intelligent Networking Features: The PCIe network adapter has auto-negotiation capabilities and is compatible with the NBASE- alliance PHY specifications. It supports hardware-based ECC and , flow control, and power-saving modes, making it suitable for energy-efficient environments. 4. Advanced Network Standard Support: This PCI Express gigabit ethernet card supports multiple Ethernet standards, including IEEE802.3bz (2.5 GBase-T), IEEE802.3az (Energy-Efficient Ethernet), IEEE802.3, IEEE802.3u, and IEEE802.. It ensures device performance while maintaining excellent energy efficiency. 5. For DSM 6.2 and above versions and ESXI 6.7U3, driver installation is required, while PVE 7.0 and above versions come with built-in plug-and-play support.
