Features
This section provides information on the features and technical data of the
PRIMERGY CX400 S2 server enclosure. For information on key characteristics
and layout of the system board, see the "PRIMERGY CX400 S2 Server
Enclosure Upgrade and Maintenance Manual".
Server enclosure
The PRIMERGY CX400 S2 server enclosure consists of the server enclosure
which has to be equipped with different configurations of server nodes, as there
are:
– 1 up to 4 PRIMERGY CX250 S2 server nodes
– 1 up to 2 PRIMERGY CX270 S2 server nodes
Hard disk drives
The server enclosure can be equipped with a maximum of 24 x 2.5 "
HDD / SSDs or 12 x 3.5" HDD modules.
Each HDD module can accommodate an SAS/SATA hard disk drive or SSD
drive with a maximum height of 1 inch. The module is connected to the
SAS/SATA backplane wirelessly. This allows HDD / SSD modules to be plugged
in or pulled out easily.
Four SAS/SATA hard disk drives can be controlled by the onboard SAS/SATA
controller. To control further SAS/SATA hard disk drives, an additional RAID
controller must be installed.
Hybrid configurations of SAS HDDs, SATA HDDs and SSDs within the same
logical drive (RAID array) are not supported.
If the server enclosure has the corresponding RAID configuration, HDD
modules can also be replaced during operation.
