Ok, I have a winders 2K box with 6 SCSI-attached LTO-1's with TSM 4.2.3.1 but it has a dual xenon 1.7G set of processors, and 1G of ram with 2G of swap space.
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
