- SAF-TE
In computer storage, a
SCSI Accessed Fault-Tolerant Enclosure is an industry standard to interface an enclosure to a (parallel) SCSI subystem to gain access to information or control concerning
* temperature
* fan status
* slot status (populated/empty)
* door status
* power supplies
* alarms
* indicators (e.g. LEDs, LCDs)Practically, any given SAF-TE device will only support part of all possible sensors or controls.Many
RAID controllers can utilize a SAF-TE 'activated' backplane by detecting a swapped drive (after a defect) and automatically starting a rebuild. A passive subsystem usually requires a manual rescan and rebuild.A SAF-TE device is represented as a SCSI processor device. For
SAS orFibre Channel systems, SAF-TE is replaced by the more standardizedSCSI Enclosure Services .The most widely used version was defined in 'SAF-TE Interface Specification Intermediate Review R041497April 14, 1997' by
