Popis produktu

The Broadcom NX-E PCIe 10Gb 2-Port Base-T Ethernet Adapter is a special mezzanine LAN-on-motherboard (mezzanine LOM) form factor adapter that also supports the Network Controller Sideband Interface (NC-SI) for communication with the server s onboard XClarity Controller (XCC) management processor. This support enables the sharing the network interface with the XCC and the operating system, thereby eliminating the need for a separate management network.


The adapters have the following specifications:
•Dual-channel 10 Gbps Ethernet controller ?10GBASE-T IEEE 802.3an support
?1000BASE-T IEEE 802.3ab support

•Based on the Broadcom BCM957416A4160C adapter and BCM57416 controller
•Supports IPv4 and IPv6
•Broadcom TruFlow flow processing engine
•PCI Express 3.0 x8 host interface
•Form factor: ?ML2 form factor (7ZT7A00497)
?PCIe low-profile form factor (7ZT7A00496)
