Overview: The high performance and reliability requirements of server environments mean that selecting the right drives for your system is critical. Compaq has developed one of the most rigorous programs for qualification continuous testing and integration in the industry to ensure that server storage customers get the best drives available.??Compaq drives undergo an intense qualification process that eliminates data integrity problems firmware and O/S incompatibilities and other causes of data corruption or premature failure. Only those drives whose performance is suitable for a server environment are selected through Compaq's qualification process and are best in class. Drive firmware has been enhanced to enable monitoring software to detect conditions in the drive parameters that are precursors to failure. Compaq Wide-Ultra SCSI drives now support S.M.A.R.T. predictive failure reporting. S.M.A.R.T. pre-failure reporting works in both array and non-array controller server environment.
