Hard disk drive (HDD) / solid state disk (SSD)
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 an 2.5-inch HDD/SSD subsystem:
– 8 SAS/SATA HDD/SSD modules or 8 PCIe SSD modules as combo drive
can be installed.
– Up to 16 SAS/SATA HDD/SSD modules or 16 PCIe SSD modules as combo
drive can be installed.
– Up to 24 SAS/SATA HDD/SSD modules or 24 PCIe SSD modules as combo
drive can be installed.
The HDD/SSD/PCIe SSD modules are connected to the HDD backplane
wirelessly. This allows HDD/SSD modules to be connected or pulled out easily.
If the HDD/SSD/PCIe SSD modules are controlled by a RAID controller,
defective HDD/SSD/PCIe SSD modules can also be replaced during operation.
In the configuration with up to 16 HDD/SSD modules, you need an SAS
controller for SAS functionality. To use full SAS speed the HDD
backplane must be connected to the appropriate SAS3.0 capable RAID
controller.
In the configuration with up to 16 HDD/SSD modules, 2.5-inch SATA
drives can be connected to SAS controller of the system board.
The configuration with up to 16 HDD/SSD modules works with a 2 or
4CPU (each CPU with <=165W) configuration or Liquid Cooling
configuration.
For information on RAID controllers controlling the HDD/SSD modules,
see
"Expansion cards and backup units" on page
Note on life time of an SSD
To monitor the life time of an SSD correctly, please ensure to use the
latest RAID Manager version. Monitoring by iRMC S5 Web UI is also
possible.
