Reliability Factors

This chapter presents factors related to the reliability of the tape drive: head life, mean time between
failures (MTBF), load/unload cycles, and tape life.

Table 10-1

lists the DLT VS80 reliability parameters and values.

Table 10-1.

Reliability Factors

Parameter

Value

Comments

Head Life

30,000 tape motion hours

Continuous operation

MTBF

200,000 hours

Quantum does not warrant that predicted MTBF is
representative of any particular unit installed for
customer use. Actual figures vary from unit to unit.
(MTBF is measured at 100% duty cycle, excluding
head life.)

Load/Unload

50,000 cycles

Excludes media errors.

Tape Life

1,000,000 passes
