Overview

The HP 9000 K-Class Hawk are multiprocessor PA-RISC servers from the mid- to late-1990s. They were part of the HP 9000 800 series of servers, and based on the U2/UTurn chipset and architecture and the Runway-based PA-7200 and PA-8000 processors. The K200s and K400s were up to four-way, the K370/K380 and K570/K580 up to six-way SMP. 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.

In the 1990s, D-Class servers were part of the US Navy TAC-4 program, in which HP was a vendor supplying RISC Unix computers for uses throughout the Navy. The D-Class were part of a technology refreshment of TAC-4 in 1996.

The K-Class naming convention for server types is as follows.
