To get the best performance from LTO drives, you need to be able to feed
them lots of data, very quickly. The test with TAR will help show where the
problem is.
I've used TSM 4.1 to backup my TSM DB and I got great thruput - mine where
attached to a SAN - the disk was also SAN attacahed.
When I tried copying lots of small files to the LTO, thruput dropped.
