PCIe dualport 2.5G Ethernet network adapter with autonegotiation and NBASET alliance PHY specifications. It includes hardwarebased ECC, flow control, and multiple powersaving modes for energyefficient environments. Key benefits Fast, reliable connectivity: supports speeds up to 2500 Mbps for throughput networking. Energy efficient: multiple powersaving modes to reduce power use in idle or lighttraffic conditions. Robust data integrity: hardwarebased ECC improves data reliability on network transfers. Flexible networking: autonegotiation and NBASET PHY compatibility optimize performance on mixed networks. Technical highlights Standards and compatibility: supports IEEE802.3bz (2.5 GBaseT), IEEE802.3az (EnergyEfficient Ethernet), IEEE802.3, IEEE802.3u, and IEEE802.. It ensures device performance while maintaining energy efficiency. Interface and performance: PCIe to 2port 2.5G Ethernet network adapter with speeds up to 2500 Mbps. Physical and power management features: includes hardwarebased ECC and flow control, plus various powersaving modes. extensive system compatibility Operating systems and platforms supported: Hackintosh, ESXI 6.7 (not compatible with 7.0), PVE, ikuai, Unraid 6.9.2, and OpenWrt. Plugandplay: generally plugandplay on supported systems. Driver considerations: for Linux, TrueNAS/FreeNAS, certain versions of OpenWrt, and older versions of ikuai, driver installation may be required. Use scenarios Virtualized server or hypervisor environment: ideal for adding speed network interfaces to ESXi 6.7 hosts or Proxmox VE systems, enabling faster VM networking and storage connectivity without upgrading existing NICs. Home NAS or media server: pairs with TrueNAS/FreeNAS, Unraid, or OpenWrtbased setups to improve data transfer rates to and from networkattached storage. Hackintosh or routerbased deployments: suitable for Hackintosh PCs or OpenWrtbased networking appliances that require reliable 2.5G connectivity and compatibility across multiple Ethernet standards.
