Overview

Time of introduction: 2002
Discontinued: September 2004

The HP zx2000 workstation is the Itanium/IA64-based brother of the PA-8800/PA-8900-based C8000 workstations. Build around the same HP zx1 chipset, the zx2000 is very similar to the C8000, delivered with Itanium 2 processors. The system is built in a sleek, silent tower casing and also available with a rack-mount option. After a relatively short time after the zx2000 HP decided to drop Itanium-based workstations. The only remaining HP-UX/Itanium-based Unix offerings are IA64-based server systems (Integrity rx).

Prices at time of introduction: US $4,000 (entry configuration), $6,000 (average) and $11,000 (large).

Internals

CPU

No.	CPU Type	Clock	L1 (I/D)	L2 (I/D)	L3
1	Itanium 2 McKinley	900MHz	16/16KB	256KB	1.5MB
1	Itanium 2 Madison	1.4GHz	16/16KB	256KB	4.0MB
1	Itanium 2 Deerfield low-voltage	1.0GHz	16/16KB	256KB	1.5MB

(It could be there are more possible processor options.)

All caches are on-die (L1, L2 and L3).

Chipset

HP zx1 chipset (same as in some PA-8800/PA-8900 workstations)
- zx1 MIO (memory and I/O controller) connects to the processor bus (6.4GB/s), memory bus (4.25GB/s) and six I/O channels (aggregate 3.0GB/s) and contains both memory and cache controllers
- Four zx1 IOAs (I/O adapters) connect the PCI-X slots and I/O devices to the zx1 MIO with an aggregate bandwidth of 3.0GB/s on six 0.5GB/s channels
  1. AGP 4x graphics bus on two channels — 1.0GB/s
  2. PCI-X 64/133 I/O slot on two channels — 1.0GB/s
  3. Four PCI-X 64/66 I/O slots on one channel — 0.5GB/s
  4. Gigabit Ethernet, IDE, USB and audio controllers on PCI 32/33 on one channel — 0.5GB/s
Gigabit Ethernet (Intel 82540)
Two-channel Ultra160 SCSI controller (optional)
Ultra ATA-100 IDE controller (PCI649)
PDH controller
Serial controller, DUART (16550A-compatible)
FPGA controller for ACPI (2.0) and LPC
Baseboard management controller (BMC — IPMI interface)
