The HP 9000 A-Class A180 and A180C were some of the last 32-bit PA-RISC HP 9000 800 servers released by HP at the end of the 1990s in a small and rack-mountable case, often used for Internet servers.

Marketed by HP fittingly as Enterprise Internet Servers they were geared towards deployment in rack-space in datacenters, and thus have no video output, only serial console and a web console.

A-Class PA-RISC system design was pretty pared down and streamlined with a simple 32-bit PA-RISC design similar to the HP Visualize B180L workstations minus graphics and some I/O devices.

A180C A5183A 1998 $16,000

The A180 servers were followed in 2000 by the newer 64-bit A400 and A500 servers, sharing their cases and external appearance but with more modern system design.

System architecture


Model CPU Speed L1 Cache L2 Cache
A180 PA-7300LC 180 MHz 64/64 KB on-chip
A180C PA-7300LC 180 MHz 64/64 KB on-chip 1 MB off-chip optional

The additional 1 MB L2 cache is the only difference between both systems. It was upgradeable through two DIMM slots near the CPU.
