This section describes how to implement the SCSI Accessed Fault-
Tolerant Enclosures (SAF-TE) Interface Specification and how to
adjust specific parameters. The DuraStor 6200S external RAID
controller is fully compliant with the SAF-TE Interface
Specification 1.04 (R041497).
What Is SAF-TE and What Are SEPs?
SAF-TE is a standardized, nonproprietary method for integrating
controllers and storage subsystems.
A SAF-TE Environmental Processor (SEP) is a SCSI device that
links the RAID controller to the storage subsystem, giving the
controller access to environmental conditions such as component
temperature, power supply and fan status, and the presence or
absence of disk drives. The RAID controller can also tell the SEP
about RAID activities such as disk drive rebuilds and failed disk
drives.
Through the SEP, the host system has access to all of this
information.
