37 Chapter 4 SCSI Storage

4.2 SAF-TE

Stands for SCSI Accessed Fault-Tolerant Enclosure. The SCA backplane

built-in GEM 318 which support SAF-TE provide a standard, non-propri-

etary way for third party disk and RAID controllers to be fully integrated

with peripheral packing that supports status signals (LED's, audible

alarm, LCD, etc), hot-swapping of hard drivers, and monitoring of enclo-

sure components, such as disks, power supplies, temperature, fans, etc.).

For ACP-7000, the GEM 318 checks the disks status only, for others as

fans, temperature, power supply and voltage are monitored by alarm

board.
