Introduction
The AcerAltos 21000 is a powerful 64-bit quad-processor system
loaded with a host of new and innovative features. The system offers
a new standard for flexible productivity ideal for local or wide area
networks and multi-user server environments.
Intel Pentium II Xeon Processor with the Intel 450NX
Chipset
The Pentium II Xeon processor, like its predecessors, the Pentium
Pro and Pentium II processors, implements a Dynamic Execution
micro-architecture - a unique combination of multiple branch
prediction, data flow analysis, and speculative execution. This means
that the Pentium II Xeon can deliver higher performance than the
Pentium Pro processor while maintaining binary compatibility with all
previous Intel Architecture processors.
Also, the Pentium II Xeon processor is available in 512K, 1MB, and
2MB L2 cache options with the introduction of the Slot 2 socket.
Unlike Slot 1 Pentium IIs, which access the L2 at half the processor
speed, the Slot 2 accesses the L2 at full processor clock speed. An
addition to the Pentium II Xeon processor is the Intel 450NX chipset,
for servers with four or more processors, which supports a 100MHz
front-side bus, USB (four ports), a south bridge to the ISA bus,
provides up to 8GB of memory support and multiple 32-bit and 64-bit
PCI buses.
In addition to meeting the mission-critical and fast system response
time requirements of enterprise servers, the AcerAltos 21000 is fault
tolerant and capable of preventing faults from occurring.
It also
demonstrates graceful performance scalability when the system
configuration is expanded.
