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.
