MGMT

HP Integrity rx2600 were rack-mountable HP Itanium workstations and servers based on the HP zx6000 workstation. Released between 2003 and 2004, rx2600 were marketed as entry-lever servers for technical and commercial applications with superior java and web benchmark as well leading integer and floating point performance.

HP rx2600 servers and zx6000 workstations were closely related, with some minor technical differences in system design – cooling, AGP slots, management ports. Both have a similar system design and can be mounted either 19″ racks (2U) or placed in a desktop tower-like enclosure

Integrity rx2600 supports up to two Itanium 2 processors with up to 1.5 GHz (Madison processor) and is targeted for PCI-X devices and thus does not feature the AGP port of the workstation-oriented zx6000. System design was based on HP zx1 chipset which was used for Itanium and PA-RISC computers in the early 2000s.

The rx2600 was later marketed as rx2600-2 and superseded by the rx2620, which supported newer processors.

Chipset

The systems are based on HP’s zx1 chipset, which consists of two main components — the MIO (memory and I/O controller) and the IOAs (I/O adapters):
