Hi All,
I had DLT7000's once, and while talking to the Quantum Engineers
while we watched ADSM use the drives, he commented on the start/stop
nature of ADSM's I/O to the drive. He told me that the drives are
optimized for data streaming, and that they would automatically fall out
of compression mode to try to stream the data. I was also told that you
could change this behavior, and force compression to be on all the time.
I had planned to do that, as I was only seeing native capacities, but I
replaced the drives with 3570's before I could look into it further.
