Overview

The rp2400/rp2430 (A400), rp2405 and rp2450/rp2470 (A500) are the 64-bit successors of the popular A180 rack servers. The chassis is similar — still 2U rack-mountable — but the interior changed significantly. The various A400/A500 models have various 64-bit PA-RISC processors with large on-chip L1 caches. The I/O subsystem is based on Astro memory/CPU controller and several Elroy PCI bridges for the various PCI slots and integrated I/O devices. The difference between the A400 and A500 is that the latter are SMP-capable and can use more memory modules and PCI cards. The rp2405 is a low-cost version, that was introduced two years later, based on very similar hardware to the A500, and could be upgraded to a rp2470.

They feature an advanced version of the Secure Web Console found in the earlier A180 systems. Called Guardian Service Processor (GSP) it can be reached with pressing Ctrl-b. It can be used for a wide range of administrative tasks; in the References section is a link to a detailed command summary.

Internals

CPU

The A400 systems are uniprocessor systems while the A500 support up to 2-way SMP. The A400 (rp2400/rp2430) and A500 (rp2450/rp2470) are based on a different system boards, which supported different types of processors:
