About the Sun Fire 880 Server
The Sun Fire 880 server is a high-performance, shared memory, symmetric
multiprocessing server system that supports up to eight Sun UltraSPARC™ III
processors. The UltraSPARC III processor implements the SPARC V9 Instruction Set
Architecture (ISA) and the Visual Instruction Set (VIS™) extensions that accelerate
multimedia, networking, encryption, and Java™ processing.
The system is housed in a roll-around tower enclosure, which measures 28.1 inches
high, 18.9 inches wide, and 32.9 inches deep (71.4 cm x 48.0 cm x 83.6 cm). The
system has a maximum weight of 288 lb (130.6 kg).
Processing power is provided by up to four CPU/Memory boards. Each board
incorporates:
■
Two UltraSPARC III processors
■
8 Mbytes of local static random access memory (SRAM) external cache memory
per processor
■
Slots for up to 16 memory modules (eight per processor)
A fully configured system includes a total of eight UltraSPARC III CPUs residing on
four CPU/Memory boards. For more information, see “About CPU/Memory
Boards” on page 62.
System main memory is provided by up to 64 next generation dual inline memory
modules (DIMMs), which operate at a 75-MHz clock frequency. The system supports
128-, 256-, and 512-Mbyte DIMMs, with future support for higher capacities as they
become available. Total system memory is shared by all CPUs in the system and
ranges from a minimum of 1 Gbyte (one CPU/Memory board with eight 128-Mbyte
DIMMs) to a maximum of 32 Gbytes (four boards fully populated with 512-Mbyte
DIMMs). For more information about system memory, see “About Memory
Modules” on page 64.
System I/O is handled by four separate Peripheral Component Interconnect (PCI)
buses. These industry-standard buses support all of the system’s on-board I/O
controllers in addition to nine slots for PCI interface cards. Seven of the PCI slots
operate at a 33-MHz clock rate, and two slots operate at either 33 or 66 MHz. All
slots comply with PCI Local Bus Specification Revision 2.1 and support PCI hot-plug
operations. You can hot-plug any standard PCI card, provided a suitable software
driver exists for the Solaris operating environment and the driver supports PCI
hot-plug operations. For additional details, see “About PCI Cards and Buses” on
page 68.
