Enclosure Management
Introduction
The DAC960PG supports enclosure management protocols. 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 DAC960PG supports the industry standard enclosure management
protocol SCSI Accessed Fault-Tolerant Enclosures (SAF-TE).
SAF-TE
The SAF-TE protocol follows a specification jointly worked out by Conner
Peripherals 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 SAFE-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.
