Lenovo ThinkSystem Broadcom NX-E PCIe 10Gb 2-Port Base-T Ethernet Adapter

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)
