Dual Lan 10G Network Card: Adopting for Intel X540 Controller, it provides up to Dual Lan 10 Gbps of extreme speed to ensure the stability of Internet access and local data transmission, effectively preventing packet loss and making the server more stable. Network Interfaces: Two independent Ethernet interfaces for 10GBASE-T, 1000BASE-T, 100BASE-TX applicationgs (IEEE 802.3an, 802.3,802.3u, and 802.3ab), supports Windows/Windows Server/Linux/Vmware/ESX. PCIe to 10Gbe RJ45: This 10G BASE-T PCIe network adapter converts PCIe slots (X8/16) into 10G RJ-45 Ethernet ports. Note: Only for PCIe ports, not for PCI slots. Adaptability and heat dissipation: Excellent heat dissipation performance can quickly reduce the temperature and keep the stability of network transmission.<br><br>Systems: for Server 2003 / Server 2008 / Vista / Win 7 / Win 8 / Win 10 32-64bit for Windows Server 2003 / 2008 / 2008 R2 / 2012 / 2012 R2 /2016 R2 for FreeBSD, Linux Stable Kernel, VMware ESX/ESXi Colour:As Shown Material:ABS<br><br>Package Contents: 1 * Ethernet Network Card<br><br>Only the above package content, other products are not included.
