Terminology
CNA (Converged Network Adapter): Combines the functionality of a network interface controller and a
storage host bus adapter. It connects to storage area networks and local area networks.
FN IOA (FN I/O Aggregator): Legacy term for FN IOM.
FN IOM (FN I/O Module): FN IOM refers to the switch modules on the rear of the Dell PowerEdge FX2/FX2s
chassis that receive and transmit network IO from the blade servers. This includes the PowerEdge FN410S,
FN410T and FN2210S. This term does not refer to pass-through modules.
LACP (Link Aggregation Control Protocol): LACP is used to control the bundling of several physical ports
together to form a single logical channel. LACP allows a network device to negotiate an automatic bundling of
links by sending LACP packets to the peer (which is a directly connected device that also implements LACP).
NIC Teaming: NIC Teaming allows multiple network interfaces on a computer to be placed into a team to
combine bandwidth or provide traffic failover to prevent connectivity loss in the event of a network component
failure.
Port Channel: Two or more network links bundled together to function as a single link. Port Channels provide
increased bandwidth, redundancy and load balancing.
ToR (Top of Rack): A switch that is positioned at the top of a server rack in a data center.
UFD (Uplink Failure Detection): When upstream connectivity fails, the FN IOM disables the downstream,
server-facing links. This feature ensures NIC teaming failovers occur properly if links are lost upstream. The
FN IOM uses LACP for the uplink port channel so it is necessary for the corresponding connections at the
upstream switch to also be configured as an LACP port channel.
