Overview

The rp2400/rp2430 (A400) 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.

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.

Introduced: May 2000, discontinued: September 2002, with prices of the entry version of $4,600 for the A400-44 and $9,200 for a single-CPU A500-5X.

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:

The following table lists the various suffixes denoting the different theoretically possible CPU configurations. Upgrading from one configuration to another could require the replacement of other parts besides the processor, e.g., the mainboard or power supply.
