Failure Trends in a Large Disk Drive Population - Research at Google
引用:
Power Cycles. The power cycles indicator counts the
number of times a drive is powered up and down. In
a server-class deployment, in which drives are powered
continuously, we do not expect to reach high enough
power cycle counts to see any effects on failure rates.
Our results find that for drives aged up to two years, this
is true, there is no significant correlation between failures
and high power cycles count. But for drives 3 years
and older, higher power cycle counts can increase the
absolute failure rate by over 2%. We believe this is due
more to our population mix than to aging effects. Moreover,
this correlation could be the effect (not the cause)
of troubled machines that require many repair iterations
and thus many power cycles to be fixed
