It was 8xATL with 8xUltrium II drives in each (64 drives total). I don't
know who specified the tape library set up, but it was definitely never the
bottleneck.

BTW my math says 1200MB/60MB = 20 drives and not 200 :) We never measured
the effective data rates of the tape drives as the SAN was the main issue in
this setup.
