Enabling QLogic Forward Error Correction
QConvergeConsole supports the forward error correction (FEC) feature, which is
a correction technique used for high-speed telecommunications devices to control
errors in data transmission over unreliable or noisy communication channels.
NOTE
The switch and the Fibre Channel end device must both support the FEC
feature. See
software version.

FEC Process Overview

The following highlights how the FEC process works between the transmitting and
receiving device:

Takes the incoming data stream.
Inserts a redundant amount of parity bits of information on the data
stream.
Sends the data stream.
Receives the data stream.
Checks for missing or corrupt data:
 If there are no corrupt or missing bits of information, the receiving
device proceeds with normal process.
 If there are corrupt or missing bits of information, the receiving
device reconstructs the original data by using pieces of the
original data stream (that are still intact) and combining those
with the parity bits of information.
