This is a method of determining the reliability of an array disk by performing a predictive failure analysis on each disk, as defined by that disk's vendor. Array Manager picks up alerts sent from each RAID controller, if the hard disk supports S.M.A.R.T.

Technology co-developed by HP and the hard drive industry that provides warning of imminent drive failure. This feature makes it possible for HP to offer Pre-Failure Warranty replacement of hard drives. S.M.A.R.T. supersedes the drive parameter tracking feature that was previously used for this purpose because the self-monitoring routines used in S.M.A.R.T. are more accurate than the drive parameter tracking tests. The self-monitoring routines are customized for that specific drive type and have direct access to internal performance, calibration, and error measurements.

A system and hard drive standard the monitors the drive's operation and looks for potential problems.

An acronym for guidelines in creating goals and strategies: S-specific, M-measurable, A-agreed upon and attainable, R-realistic and rewarded, T-timely.
