4.34 HP L1500 & L3000 (rp5430/rp5470)
4.34.1 Overview
The second incarnation of the L-Class servers are, similar to their direct predecessors L1000 and L2000,
7U rack-mountable servers with either 1-2 or 1-4 processors, 8GB or 16GB RAM and a large set of
I/O options and expandability. The internal system architecture of the L1500 and L3000 is different
however — the central parts of the processor/memory and I/O system were modified (trimmed-down)
versions of the “Stretch” chipset used in the rp7400 N4000 servers.
The L1500 features the same chassis and mainboards as the L3000, however a large set of the interfaces
(I/O, memory, processors sockets) is deactivated in hardware, limiting the L1500 to about half of the
L3000’s expansion options.
These systems only run 64-bit versions of HP-UX — 11.00 and 11i (v1 and v2). Linux could be usable
however it is unclear how solid the support is, as these machines and their architecture were rather
uncommon.
The L1500 and L3000 could be upgraded with a board-swap (mainboard, processors, etc.) to the
Itanium 2-based rx5670 servers.
Introduced: 2001-2002

4.34.2 Internals
CPU
The rp5430 (L1500) support up to 2-way and the rp5470 (L3000) up to 4-way multi-processing (SMP).
There are several classes of possible processors, both shipped with the systems or later upgraded. Sup-
port for individual processors depends on the specific system with corresponding firmware revisions,
operating system support and, lastly, the system’s support/auxiliary hardware (power supplies, voltage
changers, etc.).
Both the L1500 and L3000 came with different system boards, which supported different types of
processors:
L1500 (rp5430): up to two CPUs, system boards support all processors from 550MHz to 750MHz
L3000 (rp5470): up to four CPUs, with the processor type depending on the exact model number
[unsure which models support the 875MHz PA-8700+]:
– A6144A: 550MHz processors
– A6144B: 550MHz, 650MHz and 750MHz processors
– A6840A: 550MHz, 650MHz and 750MHz processors
– A8328A: 550MHz, 650MHz and 750MHz processors
Processor types are indicated with the following suffixes:
-5X: PA-8600 550MHz with 512/1024KB on-chip I/D L1 cache each
