HP L1000 & L2000 (rp5400/rp5450) Servers
4.33 HP L1000 & L2000 (rp5400/rp5450) Servers
4.33.1 Overview
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 combina-
tion 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.
Introduced: October 1999.
Model numbers:
L1000-36, L1000-44, L1000-5X: rp5400
L2000-36, L2000-44, L2000-5X: rp5450
4.33.2 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 fol-
lowing 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.
