Thanks for the clarification. We too have the 3592 drives, so our setups
are ~almost~ identical so your numbers give me a good ballpark on real
world throughput I might expect. I appreciate you sharing that info with
us.

Yep 594GB Vols, @ 1-4 Vols per pool, so we have 594GB to 2TB TSM Pools.
Also I forgot to mention we are writing to 3592 Tape Drives connected to
2GBs SAN ports.

Charles

Thanks for the info, we have similar hardware and are thinking about
finally moving TSM to the SAN.

        one question though on the last "TSM" section, did you mean to
say, "Defined 594~GB~ Disk Vols in TSM Storage Pool from 1-4 Vols per
pool". Just looking at the math, I'm not sure you could (or would want
to) make 594 individual volumes 


Thanks,
Ben
