Introduction
- October 1999
These 7U rack-mountable SMP servers supported either up to two (L1000/rp5400) or up to four (L2000/rp5450) 64-bit PA-RISC processors. In contrast to their L1500/L3000 sucessors the L1000/L2000 were based on a rather conservative system architecture, using the Astro/Elroy main chipset combination used in many other four-digits workstations and servers.
The L1000 and L2000 could be upgraded with a board-swap (mainboard, processors, etc.) to the Itanium 2-based rx5670 servers.
Internals
CPU
Both the L1000 and L2000 came with two different system boards, which supported different types of processors (A versus B suffix on the model number).
- L1000 (rp5400): up to two CPUs, with the processor type depending on the exact model number:
- A5576A: 360MHz and 440MHz processors
- A5576B: 360MHz, 440MHz and 550MHz processors
- L2000 (rp5450): up to four CPUs, with the processor type depending on the exact model number:
- A5191A: 360MHz and 440MHz processors
- A5191B: 360MHz, 440MHz and 550MHz processors
The L1000/rp5400 systems support up to 2-way and the L2000/rp5450 up to 4-way SMP. 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.
- -36: PA-8500 360MHz with 512/1024KB on-chip I/D L1 cache each
- -44: PA-8500 440MHz with 512/1024KB on-chip I/D L1 cache each
- -5X: PA-8600 550MHz with 512/1024KB on-chip I/D L1 cache each
It is possible not all system boards shipped with these L1000/L2000s support all possible processors.

Expansion
- Six PCI 64-bit/33MHz slots on two independent buses:
- pci0: Slots 1 and 2 are reserved for the Core I/O cards
