Introduction

The PRIMERGY CX400 S2 server enclosure represents the first generation of
multi-node systems for large data centers as well as for small and medium size
environments. It is the 2U rack optimized enclosure to be filled with standard
infrastructure, components and applications. Due to its conventional front-to-
back cooling and rear side external connectivity it enables for cost-effectiveness
through installation and operation in existing rack infrastructures and air
conditioning. A low level of complexity is granted by avoiding sharing of fabrics,
I/O or management components. The main ingredients like server nodes, power
supply units (PSUs) and disk drives are hot-plug enabled for enhanced
availability and lowered servicing effort. The approach to minimized energy
consumption is underlined by up to two highly efficient (92%) 80Plus Gold
PSUs, providing power for all built-in parts.
Efficient cooling is guaranteed by the four centrally installed fan units. The
system offers free choice between server nodes without (1U) and with (2U)
GPGPU (General Purpose Computing on Graphics Processing Units),
depending on the specific applications' characteristics. All server nodes are
half-wide, thus two of them may be positioned besides each other, and up to
four 1U or two 2U nodes are the maximum number per PRIMERGY CX400 S2
server enclosure, thus density may be doubled compared to standard rack
servers. Great flexibility is given through the different types of local disk drives,
being installed at the enclosure front side. Up to twelve 3.5 or twenty-four 2.5
storage drives are usable, be it HDDs or SSDs, both with either SATA or SAS
interfaces. The drives are assigned to the installed server nodes group wise,
adaptable to any demand and wallet.
The highly compact server enclosure occupies two height units (HU) in the rack.
