Description
MM (xe6) Motion Meters
FFP equiv. The approximate amount of full file passes worth
of data that is processed when you stream data
with low space, locate commands, and standard
number of rewinds.
TB equiv.
The approximate data processed (in TB) if
streaming data with low space and locate
commands and standard number of rewinds. It
refers to the capacity to clean.
MMH Short Media Motion Hours if the drive operates at the
fastest speed with equivalent generation media for
the entire operational period.
MMH Long Media Motion Hours if the drive operates at the
slowest speed with equivalent generation media
for the entire operational period.
There are two main criteria used by the drive to call for cleaning:
• Clean Required (also known as Clean Now TapeAlert 14h):
Clean Required is triggered when the drive posts specific permanent errors or is running degraded.
It is not based on temporary or permanent error rates. The permanent errors are typically
read/write perms or servo related perm failures. Not all read/write or servo perms will trigger a
clean. The errors are typically sticky, which means that the drive may not allow data operations
unless a clean is performed, even if a power cycle occurs.
