Overview

The K-Class Hawk servers except the K100 are multiprocessor systems. The K370/K380 and K570/K580 are able to support up to six-way multiprocessing, whereas the K2x0 and K4x0 support up to four-way SMP. A typical K-Class server consists of a System Processing Unit (SPU), system console and an optional Uninterruptible Power Supply (UPS). These units then are packaged in a 19″ rack.

Internals

CPU

The 2 KB on-chip assist cache on systems with a PA-7200 is not really a true cache.

Chipset

Buses

Memory

The required access-time of the RAM modules depends on the used CPU in the system, systems with a PA-8x00 need 50ns modules, those with PA-7200 and can take up to 60ns. It is possible that slower modules will also work.
