7.2 Basic information
The HDD or SSD and the installation frame together make up the HDD module
or SSD module.
The server is shipped with one of the following HDD or SSD subsystems:
–
3.5-inch HDD subsystem
–
2.5-inch HDD/SSD subsystem
3.5-inch HDD subsystem
Up to 12 3.5-inch SAS/SA
T
A HDD modules can be installed. The HDD module
is connected to the backplane wirelessly. This allows HDD modules to be
plugged in or pulled out easily.
Hybrid configurations of SAS and SATA HDD modules are supported in
combination with an optional HDD controller.
The HDD bays can be equipped with 3.5-inch HDD modules or 2.5-inch
HDD/SSD modules, see "3.5-inch HDD and 3.5-inch installation frame" on
page 128
2.5-inch HDD subsystem
Up to eight, 16 or 24 2.5-inch SAS/SATA HDD/SSD modules can be installed.
The HDD/SSD modules are connected to the backplane wirelessly. This allows
HDD/SSD modules to be plugged in or pulled out easily. If the server has a
corresponding RAID configuration, defective HDD/SSD modules can also be
replaced during operation.
Hybrid configurations of SAS and SATA SSD / BC-SAS and BC-SATA HDD
modules are supported in combination with an optional HDD controller.
In the configuration with up to eight HDD/SSD modules, up to four PCIe
SSDs can be installed, if one PCIe SSD backplane and one Retimer
controller is installed (see Figure 84).
For information on RAID controllers controlling the HDD/SSD modules,
see "Expansion cards and backup units" on page 215.
