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 K
— 1, 2, 3, 4 or 5 — indicates the system type and configuration:
- K100 are single-CPU with limited expandability
- K2x0 with up to four CPUs, better expandability and memory
- K3x0 with up to six CPUs and more I/O slots
- K4x0 with up to four CPUs, more I/O slots and more memory
- K5x0 with up to six CPUs and a different I/O configuration
The number after that [00, 10, …, 80] indicates the system design with CPUs and chipset.
