Intel SC5250-E User Manual

 

The server chassis SC5250-E hot-swap SCSI backplane board set performs the tasks 
associated with hot-swappable SCSI drives, enclosure (chassis) monitoring and management, 
as specified in the SCSI-Accessed Fault-Tolerant Enclosures Specification (SAF-TE), Revision 
1.0. The SAF-TE specified features supported by the hot-swap SCSI backplane include, but are 
not limited to monitoring the SCSI bus for enclosure services messages, and acting on them 
appropriately. Examples of such messages include: activate a drive fault indicator, power down 
a drive that has failed, and report backplane temperature. 

The SAF-TE intelligent agent acts as a proxy for “dumb” I

C devices during intra-chassis 

communications. These devices have no bus mastering capability. 

Up to two SATA backplanes (supporting up to eight drives) can be mounted in a Server Chassis 
SC5200 if a SATA controller is installed. One SATA backplane can be mounted in the Server 
Chassis SC5250-E. Each SATA backplane supports the connection of up to four SATA drives.  
When two SATA backplanes are mounted, one is designated the ‘Primary SATA Backplane’ 
and the second is designated the ‘Secondary SATA Backplane’.  These terms are used to be 
consistent with other backplanes in other server system products.
