Thanks for your replies.
According to IBM, 3592 J1A tape drive has Compressed sustained data rate of
80 MB/s and Maximum interface burst transfer rate of 200 MB/s

active, when all buffers are loaded, etc.
'Burst transfer rate' is the highest rate you can expect data to travel
through the connection at any given time. For example, there may be a
burst of data to be
longer.

Hi,
What do "sustained data rate" and "burst transfer rate" mean? I appreciate
your explanation or any reference.
Thanks
Network data transfer rate is the rate when the client is actually sending the
data. Usually very close to the wire speed. Aggregate is amount of data
transferred divided by the backup's elapsed time. Not just the time the client
is actually moving data on the wire. If you don'
I have a question about aggregate data transfer rate. Why it is always a
lot slower than the network data transfer rate?

Dear TSMers,
As I understand (pls correct me if i'm wrong), network data transer rate =
total no. of bytes transferred / data transfer time &
Aggregate data transfer rate = total no. of bytes transferred / elapsed
processing time,
where elapsed processing time include data transfer

What is the file structure that you are backing up? Are there a LARGE amount
of small files the client needs to process? What is the copy serialization
,
possibly that can add alot of time.
Just some wild guesses.
