Network adapters
The SR860 has an integrated 10Gb Ethernet controller, based on the Intel Ethernet Connection X722. The
X722 has the following features:
Integrated into the Intel PCH chipset
Supports 1GbE or 10GbE connections, depending on the selected LOM Phy adapter
Offers VXLAN/NVGRE hardware offloads
Supports VMDq and SR-IOV for advanced virtualization
Supports iWarp RDMA
To provide connectivity to the X722, the SR860 supports six different LOM (LAN on Motherboard) cards
which provide the Ethernet PHY function. Only 1 LOM card can be installed. See Figure 3 for the location
of the LOM slot.
The LOM card supports NC-SI to allow the network connection to be shared between the operating
system and the XClarity Controller (XCC) management module (also known as IMM, short for integrated
management module). The LOM also supports Wake-on-LAN (WOL).
For more information about the X722 controller, see the Lenovo Press product guide:

The following table lists the supported LOM cards.
Note: None of the LOM cards listed in the table support speeds lower than 1 Gbps.
