PRIMEPOWER 850 Features
world at only 17U. This extremely compact cabinet accommodates a DAT drive, DVD drive, hard disk units, plus 16
PCI slots for external connections required by the server in supporting a significant networked environment. In
addition, taking the importance of reliability into consideration, redundant PSU and dual power feed options are
supported and can be mounted in the cabinet. It's compactness allows it to be mounted it in the same rack as a disk
array and the various other I/O units required for a fully operating solution. Limited installation space in an office or
computer center environment can therefore be effectively used.
In order to prepare for and manage the occurrence of processor, memory, or I/O bus errors, a degradation function is supported
that isolates the faulty location at system restart . In addition, essential components such as the disks, power supplies, and fans
are available in redundant configuration, with hot swappable components (components that can be exchanged during
operation) supported as well. By employing these measures, high system availability has been achieved.
For flexibility in expansion of the number and types of networks, the same 19-inch rack compatible, 4U PCIBOX (PCI slot
expansion unit) system configuration as available with the 650 model, can be used. In this case up to two of these units can be
connected, adding up to 24 additional PCI slots. This allows 40 PCI cards to be mounted in total. This enables the user to
flexibly configure the I/O units as required. PRIMEPOWER 850, with its broad power capability and ability to be easily
installed in either office or computer center environments supports the widest possible range of use for many applications.

PRIMEPOWER 650 and 850 Technical White Paper
PRIMEPOWER 850 is a larger mid-range, rack-mounted server model that can
accommodate up to sixteen 675 MHz SPARC64™ GP CPUs.
A source-synchronous method that enables ultra high-speed transmission
frequency of 540MHz on the core system bus is employed to achieve excellent
expansion of system bus performance to 41.5GB/s. Best possible mounting
structure is also adopted to improve memory access performance.
High-density mounting, where eight CPUs can be installed on the same system
board, enables short-distance transmission between CPUs resulting in reduced
latency between all eight CPUs. In addition, the use of a back-panel passage to
connect the two system boards results in further reductions in latency .
The high-speed system bus and memory design with reduced latency also
significantly improves transaction performance.
To meet the demands for high-density installation in computer rooms with limited
space, high installation ability has been achieved by employing high-density
mounting. In doing so we have created the most compact 16 CPU unit in the
