Constellation.2 SAS Product Manual, Rev. H 13 5.4 Prefetch/multi-segmented cache control The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system performance. Cache refers to the drive buffer storage space when it is used in cache operations.
14 Constellation.2 SAS Product Manual, Rev. H 5.5.1 Caching write data Write caching is a write operation by the drive that makes use of a drive buffer storage area where the data to be written to the medium is stored while the drive performs the Write command.
Constellation.2 SAS Product Manual, Rev. H 15 6.0 Reliability specifications The following reliability specifications assume correct host and drive operational interface, including all inter- face timings, power supply voltages, environmental requirements and drive mounting constraints.
16 Constellation.2 SAS Product Manual, Rev. H 6.1.3 Seek errors A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek error, the drive automatically performs an error recovery process.
Constellation.2 SAS Product Manual, Rev. H 17 Caution. The drive motor must come to a complete stop prior to changing the plane of operation. This time is required to insure data integrity. 6.2.4 S.M.A.R.T. S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology.
18 Constellation.2 SAS Product Manual, Rev. H S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of the number of errors for the current interval. This counter is referred to as the Failure Counter.
Constellation.2 SAS Product Manual, Rev. H 19 6.2.6 Drive Self Test (DST) Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST validates the functionality of the drive at a system level.
