NBU 3.4.1 Master:HP-UX 11i three-way service guard cluster Library:ADIC
scalar10k IBM Ultrium drives:[email protected], [email protected] same cabinet. We have just
benchmarked our new LTO-2 drives and they are NO FASTER than the LTO-1
drives. Are there separate tuneables for the new drives we are not looking
at?  Buffer settings, something undocumented perhaps?  We have a 3GB (bound)
FC ethernet connection on the media server so I don't think it's a network
bottleneck, disk is XP-512 (rebadged Hitachi) screaming fast disk.  Tested
same class on each type of drive, identical runtimes. ??? Thank you experts.

 Where are we going and why am I in this handbasket?
