Hard disk subsystem
There are two versions of the hard disk subsystem:
–SCSI version
–SATA version
SCSI version
The hard disk subsystem consists of a hard disk cage with up to four ULTRA-
320 SCSI hard disk modules and the SCSI backplane.
You can mount up to 4 hard disk modules into the PRIMERGY TX150S2 server.
Ultra3-Wide U320 SCSI hard disk drives are used. The hard disk drives are
mounted in modules which makes it very easy to insert or remove the hard disk.
Each module is equipped with a status indicator and an error indicator.
The hard disk subsystem can be controlled by the onboard U320 controller, a
PCI standard SCSI controller or by a SCSI RAID controller.
The SCSI IDs of the hard disk modules are predefined (see also page
02-TX150S2-63).
In the SCSI version it is possible to install a HDD extension box in two bays of
the accessible drives. By this three additional ULTRA-320 SCSI hard disk
modules can be used.
SATA version
The hard disk subsystem consists of a hard disk cage with up to four SATA hard
disk modules and the SATA backplane. Each hard disk module can accom-
modate a SATA hard disk drive with a SATA interface and a maximum height of
1 inch. The module is connected to the SATA backplane without cables via the
SATA interface. This allows hard disk modules to be simply plugged in or pulled
out.
The hard disk subsystem can be controlled by a SATA controller or by a SATA
RAID controller.
