Introduction
The SPARCengine Ultra AXi is one of the latest members of Sun’s PCI-based
platform family. The Ultra AXi motherboard conforms to the ATX form factor,
supports six PCI expansion slots, and is designed to use industry standard
peripheral devices. SPARC architecture allows direct execution of Solaris operating
environment in native mode, with CPU speeds up to 440 MHz and the capability to
upgrade to faster processors as they become available. The SPARCengine Ultra AXi
motherboard makes it possible to build a general purpose computer using the
Solaris operating environment in a simple, modular assembly. Powered by the
UltraSPARC IIi processor, the Ultra AXi is designed to meet critical, high demand
application needs.
The Ultra AXi motherboard is intended for use in reliable, high performance
applications. The Ultra AXi uses the UltraSPARC IIi processor. The design objectives
include:
■
The basis for building robust general purpose computing platforms for
communications, networking or imaging
■
Complete I/O subsystem: Ethernet, keyboard, mouse, serial ports, parallel port,
disk drives and floppy disk
■
Industry standard components
■
Industry standard expansion: six 32-bit PCI slots
■
Industry standard DRAM DIMMs, monitor, enclosure, and power supply
