7 Networking and PCIe

The Dell PowerEdge R820 offers balanced, scalable I/O capabilities, including integrated PCIe 3.0
capable expansion slots. Dell Select Network Adapters, Dell's network daughter cards, let you
choose the right network fabric without using up a valuable PCI slot. Pick the speed, technology,
vendor and other options such as switch independent partitioning, which lets you share and manage
bandwidth on 10GbE connections.

Select Network Adapter

The Select Network Adapter family includes flexible LAN on Motherboard (LOM) card options for the
Dell PowerEdge 12th generation servers. The Select Network Adapter form factor delivers the value
of LOM integration with the system, including BIOS integration and shared port for manageability
while providing the flexibility of a modular card.
The R820 supports one custom rack network daughter card (NDC), as part of the Select Network
Adapter family, to house the complete LOM subsystem. The NDC is a custom form factor card that
contains a complete NIC subsystem. The NDC options supported on the R820 include a selection of
1GbE and 10GbE port cards, such as 1000 Base-T, 10Gb Base-T and 10Gb SFP+.
