About the Sun Fire V480 Server
The Sun Fire V480 system is a high-performance, shared memory, symmetric
multiprocessing server that supports up to four 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, which is mountable in a 4-post or 2-post rack, measures 8.75 inches
(5 rack units - RU) high, 17.6 inches wide, and (without its plastic bezel) 24 inches
deep (22.225 cm x 44.7 cm x 60.96 cm). The system weighs approximately 88 lb
(39.9 kg).
Processing power is provided by up to two dual CPU/Memory boards. Each board
incorporates:
■
Two UltraSPARC III Cu 900-MHz processors
■
8 Mbytes of local static random access memory (SRAM) external cache memory
per processor
■
Slots for up to 16 dual inline memory modules (DIMMs)—eight per processor
A fully configured system includes a total of four UltraSPARC III CPUs residing on
two CPU/Memory boards. For more information, see “About the CPU/Memory
Boards” on page 31.
System main memory is provided by up to 32 next-generation DIMMs, which
operate at a 75-MHz clock frequency. The system supports 256-Mbyte, 512-Mbyte,
and 1-Gbyte DIMMs. Total system memory is shared by all CPUs in the system and
ranges from a minimum of 2 Gbytes (one CPU/Memory board with eight 256-Mbyte
DIMMs) to a maximum of 32 Gbytes (two boards fully populated with 1-Gbyte
DIMMs). For more information about system memory, see “About the Memory
Modules” on page 32.
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 six slots for PCI interface cards. Four 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. For additional details,
see “About the PCI Cards and Buses” on page 35.
Internal disk storage is provided by up to two 1-inch, hot-pluggable, Fibre
Channel-Arbitrated Loop (FC-AL) disk drives. Both single and dual loop
configurations are supported. The basic system includes an FC-AL disk backplane
that accommodates two 36-Gbyte or 72-Gbyte disks. The system also supports
external mass-storage solutions, with an external FC-AL port located on the system’s
back panel. See “Locating Back Panel Features” on page 20.
