Chapter 3 Hardware Configuration 63
The UltraSPARC III microprocessor is a high-performance, highly integrated
superscalar processor implementing the SPARC V9 64-bit Reduced Instruction Set
Computing (RISC) architecture. The UltraSPARC III processor supports both 2D and
3D graphics, as well as image processing, video compression and decompression,
and video effects through the sophisticated Visual Instruction Set (VIS) extension.
VIS provides high levels of multimedia performance, including real-time video
compression and decompression and two streams of MPEG-2 decompression at full
broadcast quality with no additional hardware support.
The Sun Fire 880 server employs a shared-memory multiprocessor architecture with
all processors sharing the same physical address space. The system processors, main
memory, and I/O subsystem communicate via a high-speed system interconnect bus,
operating at a clock rate of 150 MHz. In a system configured with multiple
CPU/Memory boards, all main memory is accessible from any processor over the
system bus. The main memory is shared logically by all processors and I/O devices
in the system.
For information about memory modules and memory configuration guidelines, see
“About Memory Modules” on page 64.
Note – After installing a CPU/Memory board, you must perform a reconfiguration
boot in order for the operating system to recognize the new device. See “How to
Initiate a Reconfiguration Boot” on page 55.
Note – All internal options (except disk drives and power supplies) must be
installed only by qualified service personnel. For information about installing or
removing CPU/Memory boards, see the
Sun Fire 880 Server Service Manual , which is
included on the Sun Fire 880 Documentation CD .
Caution – Either a CPU/Memory board or an air baffle must be installed in each
CPU/Memory slot at all times. After removing a CPU/Memory board, you must
install a replacement board or an air baffle immediately to avoid an automatic
thermal shutdown. For more information, see “Environmental Monitoring and
Control” on page 16.
