7 Networking and mezzanine cards

The Dell PowerEdge M820 offers balanced, scalable I/O capabilities, including integrated PCIe 3.0

capable mezzanine card slots. Dell Select Network Adapters, Dell's network daughtercards, let you

choose the right network fabric without using up a valuable mezzanine card slot. Pick the speed,

technology, vendor and other options such as switch independent partitioning, which let you share

and manage bandwidth on 10GbE connections.

Installation of mezzanine cards requires an M1000e I/O module (IOM) of the same fabric technology

to be installed in the corresponding fabric slot of the mezzanine to support data flow through that

fabric or slot.

The Select Network Adapter family is purpose-built and includes flexible LAN on motherboard (LOM)

card options for Dell PowerEdge 12

-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 PowerEdge M820 supports two custom network daughtercards (NDC), as part of Select

Network Adapters family, to house the complete LOM subsystem. There are two form factors of

Select Network Adapters — one for blade servers and one for rack servers. The blade network

daughtercard options supported on the M820 provide dual-port 10GbE interfaces.
