Enable Time-based Access Order System (TAOS)

Time‐based Access Order System (TAOS) is a way to speed up the time it
takes to read several data segments from a single tape. Given a host‐
provided list of proposed reads, the Spectra Logic tape library provides a
list back to the host that has been re‐ordered to achieve a minimal total
read time. The intent of TAOS is to minimize the re‐positioning the drive
must do between reads of multiple locations, to improve the overall read
time and reduce drive and media wear by limiting the total travel amount
of the media within the drive. This feature is supported for LTO‐7 and later
generation drives.
Important
TAOS should only be used when recommended by Spectra Logic Technical Support.
