Fibre Channel Data Constructs Fibre Channel Data Constructs
o Frames are individual units of transfer that can typically contain mapped commands or data packets from ULPs.
The maximum frame payload size is 2112 Bytes (including optional headers) with a typical maximum data payload of 2048 bytes.
The receiving port may only be able to handle 2KB or 1KB frames, so the FC-4 layer must break up Information Units into correctly sized chunks for delivery by Fibre Channel.
o Exchanges are bi-directional groups of sequences which describe a conversation between two nodes.
