TSM LTO-3 Performance Settings

I just got this info from our architect who attended an IBM tape seminar. It was stated during the seminar that to get peak performance out of LTO-3 in TSM you need to set the following parameters:

These apply to TSM 5.3

  • TXNBytelimit       2GB

  • TXNGroupmax     65000

  • MOVESizethres    2GB

  • MOVEBatchsize   1000

I have heard of some issues with using the full 65000 on the TXNGroupmax setting, but if you want best performance these settings need to be used.

  1. Chad,

    Thanks for the info in this post. We are upgrading TSM v5.2 to v5.3 and moving from LTO2 to LTO3 so this is great!
