In my experience fiber is less problematic then copper. We have 1200
servers in our main data center with 2 or 4 nics in each. Probably about
1/2 of them are connected with fiber. It is extremely rate to see an
error on a fiber port. The copper connections on the other hand we see
problems with all the time. I guess the percentage is probably not that
high, but they do give problems. The problems are mostly with bad nic's,
but also some bad cable problems. The server group knows this and usually
go fiber nics when they install a mission critical server.
