Media Lifecycle Management Overview
This section provides an overview of how BlueScale Media Lifecycle 
Management (MLM) works in your library. See 
 for detailed information about using MLM.
Media Tracking and Reporting   Media Lifecycle Management records 
30 data points every time a tape is loaded, giving you vital statistical and 
diagnostic information that helps you proactively manage your tape media 
throughout its life. BlueScale Media Lifecycle Management (MLM) 
provides media tracking and reporting that lets you review data about 
every MLM-compatible tape and cleaning cartridge in your library and 
generate reports about media health. You can generate summary reports 
with a health overview for the media in the whole library or an individual 
partition or you can generate more detailed reports with information about 
compression ratios, load counts, write errors, encryption status, and more. 
You can also view detailed information about individual cartridges. 
BlueScale MLM reporting helps you identify tapes with high error rates or 
other problems (for example, a dropped leader). These tapes can then be 
removed before they cause data corruption. Use BlueScale reporting to 
help identify damaged tapes and dirty tape heads.
Spectra Logic Memory Chip Data   Media Lifecycle Management starts with 
packaged, bar-coded, MLM-capable, Certified Media (LTO-3 and LTO-4) 
and MLM-capable Certified LTO cleaning cartridges from Spectra Logic. 
Before shipment, Spectra Logic writes baseline data, including its bar code 
information and the date on which the media was certified, to the memory 
chip embedded in each cartridge. Throughout its life, the cartridge 
continually collects data on its memory chip. Whenever a drive unloads a 
cartridge, the drive writes information about the tape to the cartridge 
memory chip.
