Reliability Factors

The mean interval between failures of the library unit, less the tape

drives, is:

• 185,000 Power-On Hours (POH) Mean Time Between Failures

(MTBF),

• 1,000,000 Mean Load/Unload Cycles Between Failures

(MCBF),

where a failure is charged against one or the other, but not both.

Quantum|ATL does not warrant that predicted mean interval

between failures is representative of any particular unit installed

for customer use. Actual figures vary from unit to unit.
