Adolph, the drives are Escon connections. We have two (2) channels to the
controller. There is not anyone using
the tape drives at the same time.
Thanks again

Wilfredo, then you need to look at how the drives are connected Escon or
Ficon - how many connections to the controller. Was anything else using tape
drives at the same time?
I'm seeing rates around 20MB/sec which after compression would be about
7-8MB/sec.
