Basic information
The hard disk drives or solid state drives which can be ordered for the
PRIMERGY BX920 S4 are supplied already mounted in an installation frame so
that defective drives can be replaced and new drives can be added during
operation. The hard disk drive or solid state drive and the installation frame
together make up the HDD module or SSD module.
The server blade is shipped with one of the following configurations:
– configuration with SATA HDD/SSD modules and PCH backplanes
– configuration with SAS HDD/SSD modules, PCH backplanes and onboard
controller SAS upgrade via onboard SAS enabling key
– configuration with SAS HDD/SSD modules, SAS backplanes and SAS RAID
HDD module without cache (RAID level 0/1). This option requires CPU 2
installed.
– configuration with SAS HDD/SSD modules, SAS backplanes and SAS RAID
HDD module with 512 MB cache (RAID level 0/1/1E/10/5/50/6/60). This
option requires CPU 2 installed.
Each HDD/SSD module can accommodate a SAS/SATA hard disk drive or
SAS/SATA solid state drive with a 2.5-inch format. The HDD/SSD modules are
connected to the HDD 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 HDD/SSD modules are not supported.
