Figure 24: Single Node SCSI Module
The server accesses the SCSI arives via the single node SCSI modules. i. e. it
accesses one of the SCSI channels with seven drives in all via each of the
modules. If the host possesses a RAID controller with two channels, it has two
times seven hard disk drives at its command via the two SCSI input modules.
(see
The single node SCSI module has the following functions:
●
It transmits the SCSI bus from the SCSI input socket (68 pin, ultra high
density) on the rear side of the PRIMERGY SX30 storage subsystem to the
drive backplane.
●
The SAF-TE controller on the module controls OLR functions and cabinet
diagnosis.
●
Should the drive be replaced, it generates an SCSI reset signal.
