Fujitsu PRIMERGY TX120 S2 Operating Manual page 10

Features Preface
Hard disk drives
The server has a drive cage in which up to 2 SAS/SATA HDD modules can be
inserted. Each HDD module can accommodate an SAS/SATA hard disk drive
with a 2.5-inch format. The module is connected to the SAS/SATA backplane
wirelessly. This allows HDD modules to be plugged in or pulled out easily.
SATA hard disk drives are controlled by the onboard SATA controller. An
additional SAScontroller must be installed to control SAS hard disk drives.
If the server has the corresponding RAID configuration, HDD modules can also
be replaced during operation.
A hard disk drive extension box can be installed optionally (with a maximum of
two HDD modules).
Onboard SATA controller
A 6-port 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 55.
