HP 9000 is the name for a line of computer systems produced by the Hewlett-Packard (HP) company. The first system in this line was the Series 520, introduced in 1982. An earlier model, the HP 9836, was later merged into the HP 9000 lineup as the Series 236. All models in the HP 9000 line can run the HP-UX Operating System. Many of them can also run the Linux operating system. Several models are able to run the NEXTSTEP operating system.

Initially, the HP 9000 line of computers used HP's FOCUS architecture for the Series 500. After incorporating the HP 9836 into the family, HP used Motorola's M68k architecture for its Series 200, 300, & 400. HP switched over to its proprietary RISC design, PA-RISC, for the Series 700, 800, and later lines. Current models use either PA-RISC or the successor IA-64 architecture.

N-class

The N-class is a 10U server with up to 8 CPUs and 17 PCI slots with 15 available for the customer. It uses two Merced busses, one for each set of four processor slots. It is not a NUMA machine, having equal access to all memory slots. The I/O is unequal though, having one Ike IOMMU per bus means that one set of CPUs are closer to one set of I/O slots than the other.

The N-class servers were marketed as being "Itanium-ready". Although they were ready for Itanium, when it shipped Itanium wasn't ready for them, and no Itanium upgrade was ever issued for the N class. The N class did profit from using the Merced bus, bridging the PA processors to it via a special adapter called DEW. Itanium brand logo In computing, the Itanium is an IA-64 microprocessor developed jointly by Hewlett-Packard and Intel. ...

The N4000 was upgraded with newer processors throughout its lifespan, with models called N4000-36, N4000-44 and N4000-55 indicating the processor speeds. It was renamed to the rp7410 series in 2001.

L-class

The L-class servers are 7U with up to 4 CPUs (depending on model). They have 12 PCI slots with 10 being available for customer use. They were renamed to the rp5400 series in 2001.

The L1000 and L2000 are similar to the A400 and A500, being based on an Astro/Elroy combination. They initially shipped with 360MHz PA8500 and were upgraded with 440MHz PA8500 and 550MHz PA8600.

The L1500 and L3000 are similar to the N4000, being based on a DEW/Ike/Elroy combination.

A-class

The A180 and A180C were 32-bit, single CPU, 2U servers based on the PA7300LC processor with the Lasi and Dino ASICs.

The A400 and A500 servers were 64-bit, dual CPU 2U servers based on the PA8500 and later processors, using the Astro IOMMU and Elroy PCI adapters. The A400-36 and A500-36 machines used the PA8500 processor running at 360MHz; the A400-44 and A500-44 are clocked at 440MHz. The A500-55 uses a PA8600 processor running at 550MHz and the A500-75 uses a PA8700 processor running at 750MHz.

The A-class was renamed to the rp2400 series in 2001.

Series 700

The Series 700 started with the "Snakes" workstations, the 705, 710, 720, 730 and 750. They were based on the PA7000 processor and had an NCR 53c700 SCSI controller for their onboard SCSI.

They were superseded by the 715/33, 715/50, 715/75, 725/50, 725/75, 735/99, 735/125, 755/99 and 755/125 with a PA7100 processor. The number after the / provides an indication of processor clock speed.

Increasing integration led to the introduction of the 712/60, 712/80, 712/100, 715/64, 715/80, 715/100, 715/100 XC and 725/100 workstations. These use the PA7100LC CPU and the Lasi ASIC, connected by the GSC bus. The Lasi ASIC contains an NCR 53c710 SCSI interface, the Intel Apricot 10 Mbit Ethernet interface, CD-quality sound, PS/2 keyboard and mouse, a serial and a parallel port. All except the 712 series machines also use the Wax ASIC to provide an EISA adapter, a second serial port and support for the HIL bus. GSC is a bus used in many of the HP 9000 workstations and servers. ... The Extended Industry Standard Architecture (in practice almost always shortened to EISA and frequently pronounced eee-suh) is a bus standard for IBM compatible computers. ... HIL (Human Interface Loop) is the name of a computer bus used by Hewlett-Packard to connect keyboards, mice and less common human interface peripherals to their HP 9000 workstations. ...

B, C, J class

The C100, C110, J200, J210 and J210XC use the PA7200 processor, connected to the UTurn IOMMU via the Runway bus. The C100 and C110 are single processor, and the J200 and J210 are dual processor. The Uturn IOMMU has two GSC buses. These machines continue to use the Lasi and Wax ASICs. In computing, the Runway bus is a Front side bus used by several generations of PA-RISC processors from the PA7200, through the PA8000, PA8200, PA8500, PA8600 and PA8700. ...

The B132L, B160L, B180L, C132L, C160L and C180L workstations are based on the PA7300LC processor (a development of the PA7100LC processor). These machines use the Dino GSC to PCI adapter which also provides the second serial port in place of Wax. These machines optionally have the Wax EISA adapter. 32-bit PCI expansion slots on a motherboard 64-bit PCI expansion slots inside a Power Macintosh G4 The Peripheral Component Interconnect standard (in practice almost always shortened to PCI) specifies a computer bus for attaching peripheral devices to a computer motherboard. ...

The C160, C180, C180-XP, J280 and J282 use the PA8000 processor and are the first 64-bit capable workstations. They are normally used in 32-bit mode, however. They are based on the same Runway/GSC architecture as the earlier C and J class workstations.

The C200, C240 and J2240 offer increased speed with the PA8200 processor and the C360 uses the PA8500 processor.

The B1000, B2000, C3000, J5000, J7000 were also based on the PA8500 processor, but had a very different architecture. The U2/Uturn IOMMU and the GSC bus is gone, replaced with the Astro IOMMU, connected via Ropes to several Elroy PCI host adapters.

The B2600, C3600 and J5600 upgrade these machines with the PA8600 processor. The J6000 is a rackable workstation which can also be stood on its side in a tower configuration.

The C3650, C3700, C3750, J6700 and J6750 are PA8700 processor based.

The C8000 uses the dual-core Mako processor. It has the same bus as the McKinley and Madison ia64 processors and uses the same zx1 chipset as them. The Elroy PCI adapters have been replaced with Mercury PCI-X adapters and one Quicksilver AGP 8x adapter. The title given to this article is incorrect due to technical limitations. ...
