FC is everywhere at the high end.
It was intended to be marketed as something that would displace the
parallel interfaces on the market such as SCSI and ATA.
ATA has won the low end despite its inherent problems and the large
capacity to price war.
SAS is what I see a lot of.

The cdrom drive may have hooked up directly by
SCSI to the host. The
tape drives may have been on the SSA bus.
IBM invented SSA to sabotage Fibre channel back in the day, promised
to merge it so it would be media compatable (not protocol) compatable
with FC to stop FC.
As a result, how many out there have either?
Umm, what? Unless you're in the twilight zone, FC is everywhere.
I've not seen a datacenter *without* tons of FC for many years, and it
won't be going away anytime soon. It'll get upgraded in phases as it
gets faster (4Gbps FC is en vogue now, for companies with lots of
money) but it'll be here for quite a while.
SAN-based RAID systems are, by far, the dominant large-capacity
storage mechanism in use today...and FC is, by far, the dominant
interconnect for those SANs. iSCSI has shown up here and there, but
is not typically used for large installations...it's handy to build a
SAN on an already-installed high-speed Ethernet network without adding
an entirely separate network infrastructure for FC.
