深圳市華天易達(dá)科技有限公司 INTEL2009年推出了基于intel82576芯片的新款網(wǎng)卡E1G42ETE1G42EFE1G44ET 基于英特爾的雙端口銅纜千兆以太網(wǎng)PCIExpress服務(wù)器適配卡 雙端口銅纜千兆以太網(wǎng)PCIExpress服務(wù)器適配卡是一種PCI-ExpressX4銅纜千兆以太網(wǎng)網(wǎng)絡(luò)接口卡，其PCI-Express適配卡上帶有多個/單個千兆端口。該適配卡設(shè)計用于服務(wù)器和高端設(shè)備。并且對性能進行了優(yōu)化，使系統(tǒng)I/O不再是高端網(wǎng)絡(luò)應(yīng)用的瓶頸。該適配卡能夠通過捆綁組實現(xiàn)容錯。來自故障端口的通信將被路由至同組中其他成員。該適配卡具有集成的硬件加速功能，能夠執(zhí)行TCP/UDP/IP校驗和分載以及TCP分段任務(wù)。主機處理技術(shù)可分載加速器，釋放CPU資源，以處理其他應(yīng)用程序。該適配卡是部署多個網(wǎng)絡(luò)以及在高性能服務(wù)器上部署關(guān)鍵網(wǎng)絡(luò)應(yīng)用和環(huán)境的理想解決方案。該適配卡基于英特爾82576千兆以太網(wǎng)MAC+PHY（媒體接入控制器和物理接口收發(fā)器）雙端口控制器。 E1G42ETBrandName:Intel GigabitETDualPortServerAdapterProductCode:E1G42ETEthernetController(s): Intel 82576Connector CableMedium:RJ-45Copper CablingType: Category-5 upto100mSlotType,Maximum Ports : DualPortSupportedSlotHeight(s):LowProfileandFullHeightIntel VTforConnectivity1:VirtualMachineDevice Queues(VMDq) VirtualMachineDirectConnect(VMDc)SecurityFeatures:IPSECIWARP/RDMA: NA E1G42EFBrandName:Intel GigabitEFDualPortServerAdapterProductCode:E1G44ETEthernetController(s): Intel 82576Connector CableMedium:LCFiberOptic CablingType: MMF62.5/50 m upto275mSlotType,Maximum Ports : DualPortSupportedSlotHeight(s):LowProfileandFullHeightIntel VTforConnectivity1:VirtualMachineDevice Queues(VMDq) VirtualMachineDirectConnect(VMDc)SecurityFeatures:NA E1G44ETBrandName:Intel GigabitETQuad PortServerAdapterProductCode:E1G44ETEthernetController(s): Intel 82576Connector CableMedium:RJ-45Copper CablingType: Category-5 upto100mSlotType,Maximum Ports : Quad PortSupportedSlotHeight(s):LowProfileandFullHeightIntel VTforConnectivity1:VirtualMachineDevice Queues(VMDq) VirtualMachineDirectConnect(VMDc) SecurityFeatures:IPSEC
