TX120 S3 Operating Manual 17
Functional overview
Hard disk drives
The server is shipped with one of the following drive cages:
– For up to two non hot-plug 3.5-inch SATA hard disk drives:
Up to two 3.5-inch SATA HDD modules can be used in the drive cage. Each
HDD module can accommodate an SATA hard disk drive with a maximum
height of 1 inch.
– For up to four 2.5-inch SAS/SATA hard disk drives:
Up to four 2.5-inch SAS/SATA HDD modules can be used in the drive cage.
Each HDD module can accommodate an SAS/SATA hard disk drive with a
2.5-inch format. The modules are connected to the SAS/SATA backplane
wirelessly. This allows HDD modules to be plugged in or pulled out easily. If
the server has a corresponding RAID configuration, defective HDD modules
can also be replaced during operation.
Hybrid configurations of SAS and SATA HDD modules are not supported.
Onboard SATA controller
A SATA controller is integrated on the system board; up to four SATA hard disk
drives can be connected to the controller. The LSI Embedded MegaRAID
software (SATA Software RAID) supports RAID levels 0, 1 and 10.
For more information on configuring the controller, see section "Configuring the
onboard SATA controller" on page 70.
