3–Fibre Channel Configuration
Enabling QLogic Forward Error Correction
99 BK3254601-00 J
 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.
Enabling QLogic FEC
To enable the QLogic FEC feature, submit a case to Technical Support at
www.marvell.com
, Support, or refer to the QLogic document, Application Note:
Enabling Forward Error Correction, (part number 83830-514-03).
NOTE
i
Instead of having to request retransmission of the entire data frame, the
receiving device can recreate or reconstruct the data stream itself. This
process prevents multiple CRC errors from being triggered and causing
application performance issues.
NOTE
At 32Gbps, FEC is mandatory and enabled, and does not require any user
configuration. At 16Gbps, FEC is optional and does require user
configuration. At 8Gbps, FEC is not supported.
