TSM and LTO Throughput
Ok, I have a winders 2K box with 6 SCSI-attached LTO-1's with TSM 184.108.40.206
but it has a dual xenon 1.7G set of processors, and 1G of ram with 2G of
The LTO's are in a IBM 3483-L18. There are two LTO's on each of 3 separate
SCSI chains (they are 160 adapters, de-tuned to 80 in the adapter BIOS,
because the LTO's I have won't work at 160). But even at that two LTO-1's
should not outpace a 80MB/Sec SCSI adapter.
What kind of throughput are you folks seeing with SCSI attached LTO-1's?
I am trying some timeing doing migrations right now. If others are
interested I will report back.
Why am I asking? I think I have some performance issues, just getting data
to/from tape, and can't seem to figure out where to look to find answers!
You guys being a 'similar user base' have some similar stats, that could
tell me if I am working 'as designed' or far behind the power curve.
TIA ... Jack
