Hello,

I am trying to understand why LTO is so much slower than 9840B or 9940A
when restoring a file?  I know that it takes longer to load the tape and
the performance is slightly slower, but what is the technical reason for
LTO having slow restores for files and databases?  Does anyone have any
statistics/numbers that I might be able to go by?  Right now we have 3590's
and we are getting about 25 GB/HR on the mainframe.  We are going to be
moving TSM to a SUN/Solaris server which will be put on the SAN.  Mainly I
am trying to understand what goes on when a server tries to restore a
file/database from an LTO tape and how the 9840B or 9940A is better?
Thanks in advance for any input!!!!
