LTO-9 media Optimization (some times referred to as Characterization) is a new feature for the LTO-9 tape drive with LTO-9 media. The increased number of tracks used to write data on tape requires greater precision. Media optimization creates a referenced calibration for each cartridge that enables the tape drive’s intelligent alignment to optimize data placement. LTO-9 media optimization enhances LTO tape long-term media durability.

 

Optimization what are the facts….

  • Media optimization will be performed on first load of LTO-9 media.
  • Media optimization is a one-time operation that can be completed on any drive in the environment, enabling the media to be used across all tape drives without further optimization. 
  • The previous version of LTFS 2.4.4.0 from IBM (required for LTO-9 compatibility), an LTFS format command will trigger optimization to occur of the media as part if the format process, even if the media has already been optimized.
  • The latest version of IBM LTFS 2.4.5 (released 30th June 2022) has improved the mkltfs command that improves the format/unformat time on LTO-9 (or later) drive. If is recommend that customers using LTO-9 drives upgrade to LTFS 2.4.5.
  • Media optimization averages 40 minutes per first load of a cartridge to a tape drive. Although most media optimizations will complete within 60 minutes some media optimizations may take up to 2 hours, or a little as 20 minutes.
  • The differing amount time taken for the one-time optimization to complete has no impact on the performance or functionality of the data cartridge.
  • Interruption of the media optimization process is not recommended.
  • Symply now provides optimized and labelled LTO-9 data cartridges included in our product, and as an option for additional media ordered in packs of 5.   Custom barcode labels are available in MOQs of 5 cartridges.
  • Symply offer LTO-9 media for purchase via our network of resellers, this is available with or without pre-optimisation performed.
