7 Networking and PCIe
The PowerEdge R920 offers rack network daughter card (RNDC) options which provide a custom
solution that contains a complete network interface controller (NIC) subsystem. The R920 supports
one RNDC card instead of the traditional LAN on motherboard (LOM) design. RNDC offer the
features and benefits of a traditional LOM subsystem (including NC‐SI management interface) but
with expanded features and added flexibility as RNDCs provide an easy upgrade path from 1GB to
10GB LAN speeds.
