Table 23 Reliability Specifications

Mean Time Between Failures

The LTO-3 Half-Height Tape Drive is designed for maximum reliability and data integrity. Table 23 lists the reliability specifications.

Specification	Description

Cartridge load/	100,000 cartridge load/unload cycles (no
unload	thread)

Error recovery and	• Error correction code techniques
control	(C1 and C2 ECC)
	• Read-after-write (RAW)
	• Error monitoring and reporting (error log)
	• Retry on

Mean time between	250,000 hours MTBF at 100% duty cycle:
failures (MTBF)	power applied and tape moving continuously
	(tabletop drive; 50,000 hours at full load and
	25°C)

Mean time to replace	Less than 30 minutes
(MTTR)

Nonrecoverable error	Less than 1 in 1017 bits
rate

The mean time between failures (MTBF) for the internal drive is specified at 250,000 hours minimum. This specification includes all power-on and operational time but excludes maintenance periods. Operational time is assumed to be 100% of the power-on time. Operational time is the time the tape is loaded.
