SCSI Accessed Fault-Tolerant Enclosures Interface, R041497: Specification
The document provides specification for the SCSI accessed fault-tolerant enclosures (SAF-TE) interface, which provides a standard, nonproprietary way for third-party disk and RAID controllers to be automatically integrated with peripheral packaging that supports status signals (LEDs, audible alarm, LCD, etc.), hot swapping of hard drives, and monitoring of enclosure components. It also allows a selected controller to work with a variety of expansion packaging, being fully able to sense status and drive enclosure indicators. The cost of a separate cable and interface for enclosure services is also eliminated.
