The second version of HP 9000 L-Class are multi-processor Unix servers based on the Stretch chipset, also used in rp7400 N4000 servers. They are similar to L1000 and L2000, 7U rack-mountable with up to two or four processors, 8 GB or 16 GB RAM and a large set of I/O options and expandability.

L1500 have the same chassis and mainboards as L3000 with some I/O, memory and processors sockets deactivated in hardware, limiting the L1500 to about half of the L3000 capacity. Both could be upgraded to Itanium 2-based rx5670 servers.

HP L1500 rp5430 were introduced in 2001
HP L3000 rp5470 were introduced in 2001 for $39,000

System architecture

Processors

rp5430 L1500 support up to 2-way and rp5470 L3000 up to 4-way multi-processing (SMP). There are several classes of possible processors, both shipped with the systems or later upgraded, designated by the [-5X, -7X, …, -9X] suffix, based on different L3000 board configurations (A6144A, A6144B, A6840A).

Chipset

The chipset is based around the HP Stretch chipset:

HP Prelude memory controller, the main crossbar of the system
HP DEW Runway converters, attach the CPUs to the system bus
HP IKE I/O controller connects the PCI bridges to the system main bus
rp5430 Seven HP Elroy PCI bridges, attach PCI buses to the IKE I/O controller
rp5470 Ten HP Elroy PCI bridges, attach PCI buses to the IKE I/O controller
DEC 21142/43 Fast Ethernet controller (Tulip)
Symbios Logic 53C875 16-bit Ultra-Wide SCSI-2 controllers
Symbios Logic 53C896 Ultra2-Wide SCSI-3 controller

System buses

Two Itanium system buses, 133 MHz DDR, each 2.1 GB/s peak, combined 4.3 GB/s aggregate. Both system buses connect to the central Prelude memory controller.
Runway+/Runway DDR CPU buses, each 2.1 GB/s peak. Either two or four buses depending on the number of CPUs, with a combined aggregate 4.3 or 8.6 GB/s
Two memory bused with combined 4.3 GB/s peak. 133 MHz DDR at 64-bit with ECC
rp5430 Eight I/O channels, each 133 MHz 256 MB/s — 2.1 GB/s aggregate
- Five PCI-64/66 I/O buses for expansion slots
