PRIMEPOWER 650 Features
improves transaction performance.
To meet the demands for high-density installation in computer rooms with limited space, high installation ability has
been achieved by the use of high-density mounting. We have created the most compact eight CPU system in the world
at 8U. The extremely compact cabinet accommodates a DAT drive, DVD drive, two hard disk bays, plus eight PCI
slots for the external connections required to support 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. Its compactness makes it possible to mount 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 a processor, memory, or I/O bus error, 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 type of networks, a 19-inch rack compatible, 4U PCIBOX (PCI slot
expansion unit) system configuration is employed. By connection of these additional units, a further 12 PCI slots can
be added, so that PCI cards can be mounted in up to 20 slots in total. This enables the user to flexibly configure the
required I/O configurations. . PRIMEPOWER 650, with its ability to be easily installed in either an office or computer
center environment, supports the widest range of use for many applications.

PRIMEPOWER 650 and 850 Technical White Paper
GP processors @ 675 MHz, 8 MB secondary cache
™
PRIMEPOWER 650 is a mid-range, rack-mounted
server model that can accommodate up to eight 675
MHz SPARC64™ GP CPUs.
A source-synchronous method that enables an ultra
high-speed transmission frequency of 540MHz on
the core system bus is employed to achieve
significant expansion of system bus performance to
13.8GB/s. The best possible mounting structure has
been adopted to improve memory access
performance. This 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 high-speed system bus and
memory design with reduced latency significantly
