Overview

The HP 9000 K-Class Hawk are multiprocessor PA-RISC servers with up to four-way SMP in the K2x0 and K4x0, and up two six-way SMP in the the K370/K380 and K570/K580. A typical K-Class server consists of a System Processing Unit (SPU), seperate system console and an optional UPS, bundled into a single 19″ rack.

The first number after the K1, 2, 3, 4 or 5 — indicates the system type and configuration:

The number after that [00, 10, …, 80] indicates the system design with CPUs and chipset.
