Mylex’s AcceleRAID controllers support the industry standard enclosure 
management protocol SCSI Accessed Fault-Tolerant Enclosures (SAF-TE). 
This feature allows the host to monitor drive enclosures and detect certain 
faults or operating environment conditions. The host can make a decision to 
shut down the system or issue a warning based on the type of fault detected.

The SAF-TE protocol follows a specification jointly worked out by Conner 
Corporation and Intel Corporation. Enclosures that are compliant with this 
protocol are known as SCSI Accessed Fault-Tolerant Enclosures (SAF-TE). 
The protocol is compatible with standard SCSI buses and cabling.

The SAF-TE interface standard’s objective is to provide a non-proprietary 
means of allowing third-party disks and controllers to be automatically 
integrated with peripheral enclosures that support:

• Status Signals (LEDs, audible alarms, LCDs, etc.)

• Hot swapping of drives

• Monitoring of fans, power supplies, and enclosure temperature

SCSI is the underlying transport mechanism for communicating enclosure 
information. All standard SCSI host adapters will work. There is no need to 
consider reserved signals or special cabling.

The SAF-TE interface can be implemented as a SCSI target that uses a SCSI 
port and an 8-bit microcontroller.

All communication is initiated by the host. The SAF-TE processor acts only 
in target mode. The SAF-TE processor is periodically polled by the host 
approximately every 2 to 10 seconds.
