Supermicro AOC-STG-B4S Add-on Card Server Adapter



The Lowest Power and Highest Performance 4-port 10GbE Controller in The Market

Proving once again that "We Keep IT Green", Supermicro introduces a new 4-port 10GbE controller featuring the lowest power consumption in the industry. TheAOC-STG-b4Suses the Broadcom BCM57840S controller to offer a broad selection of popular networking features including TCP Offload, support for PXE boot and Virtualized Environments (VMDq and PC-SIG SRIOV), and Energy Efficient Ethernet (IEEE 802.3az). For the lowest power and highest performance, the AOC-STG-b4S is the best choice for high speed Ethernet connectivity for Supermicro servers.
