HP Integrity is series of Hewlett-Packard server computers produced by Hewlett-Packard since 2003, based on the Itanium processor architecture. The Integrity brand name was inherited by HP from Tandem Computers via Compaq.
HP supports the Windows Server, HP-UX 11i, OpenVMS, NonStop, Red Hat Enterprise Linux and SuSE Linux Enterprise Server operating systems on Integrity servers.[1]
Earlier Integrity servers were based on two closely related chipsets. The zx1 chipset supports up to 4 CPUs and up to 8 PCI-X busses. The sx1000 chipset supports up to 64 CPUs and up to 192 PCI-X buses. The successor chipsets are the zx2 and sx2000 respectively.

The 1U rx1600 server is based on the zx1 chipset and has support for one or two 1 GHz Deerfield Itanium 2 CPUs.
The 1U rx1620 server is based on the zx1 chipset and has support for one or two 1.3/1.6 GHz Fanwood Itanium 2 CPUs.
Common for the series is:
Optional features are:
The series support four operating systems:
The 2U rx2600 server is based on the zx1 chipset and has support for one or two 1.0/1.4 GHz Deerfield/Madison, 1.3 GHz Madison or 1.5 GHz Madison CPUs.
The 2U rx2620 server is based on the zx1 chipset and has support for one or two 1.6 GHz Fanwood/Madison or 1.4/1.6 GHz Montecito CPUs.
The 2U rx2660 server is based on the zx2 chipset and has support for one or two 1.6 GHz Montvale or 1.42/1.66 GHz Montvale CPUs.
Common for the series is:
Optional features are:
The series support four operating systems:
The 2U rx2800 i2 server utilizes the Intel Itanium 9300 series chipset with 8, 4 or 2 processor cores available. Among features common for the series(HP Integrity Entry-class rx2800-i2 Overview) is:
The series supports three operating systems:
The 4U rx3600 is based on the zx2 chipset and has two CPU sockets which support Montecito or Montvale processors. It supports up to 96 GB of main memory, using 24 four-gigabyte DIMMs.
Standard features include:
Optional features:
The 7U rx4610 utilizes Itanium 1 CPUs with support for up to four single-core CPUs, 64GB RAM and 10 PCI 64-bit slots.
The 4U rx4640 utilizes Itanium 2 CPUs with support for up to four dual-core CPUs, 128 GB RAM and 6 PCI-X slots.
Both of these models come with integrated USB and video as default, which enables support for Microsoft Windows operating systems out of the box. The rx4640 is architecturally the same box as the rp4440, and can be changed from PA-RISC to Itanium 2 support with the flip of a switch.
The discontinued 7U rx5670 server has four CPU sockets which support McKinley and Madison processors. It is zx1-based and can have up to 48 DIMM slots, supporting 256 MB to 2 GB DIMMs which must be loaded in matched sets of four (quads). It has 9 PCI-X slots and 1 PCI slot available.
The 7U rx6600 is based on the zx2 chipset and has four CPU sockets that support Montecito and Montvale CPUs. It supports 384 GB memory using 48 eight-gigabyte DIMMs.
Standard features include:
Optional features:
HP's mid-range and high-end (Superdome) servers are based on cell boards, sometimes called cells,[2] which contain the chipset, Processors, memory, and I/O bus. This design allows the servers to be divided into hardware partitions, or groups of cell boards. Each partition is able to perform as if it were a separate server.
The 10U rx7620 is based on the SX1000 chipset which supports both PA-RISC and Itanium 2 CPUs.
The 10U rx7640 is based on the SX2000 chipset which supports both PA-RISC and Itanium 2 CPUs.
The rx7600 series are the smallest cell-based servers from HP. Just like the bigger rx8600 (see below) and the HP Superdome (see below), these servers can be partitioned, either as one big partition (two cells in one partition) or as two independent cells.
The 17U rx8620 is based on the SX1000 chipset which supports both PA-RISC and Itanium 2 CPUs.
The 17U rx8640 is based on the SX2000 chipset which supports both PA-RISC and Itanium 2 CPUs.
Standard features:
Just like the smaller rx7600 (see above) and the HP Superdome (see below), the rx8600 can be partitioned using any combination of the four available cell boards (minimum of one, maximum of four separated partitions).
The maximum number of partitions is four when used with an I/O-expander unit (IOX). Because each partition requires an available I/O slot, and the rx8600 series' integrated I/O-chassis statically maps its two I/O slots to cell board 0 and 1, an rx8600 series system is limited to two partitions unless an IOX is installed.
Cells can be freely moved from a rx7600 series to a rx8600 series as long as the chipset is the same on the cells, and the firmware is compatible.
The Superdome server is available in several models, including the SD-16, SD-32, and SD-64. HP announced Superdome 2 in April 2010, offering resiliency improvements, a modular, bladed design, common components and Crossbar Fabric that routes transactions to the optimal pathway between blades and I/O.[3] Superdome 2 addresses requirements for high-performance computing by providing flexible scalability and fault tolerance necessary for mission-critical workloads.[4]
On November 22, 2011 HP announced Project Odyssey - a project to redefine the future of mission-critical computing with a development roadmap that will unify UNIX® and x86 server architectures on a single platform. The roadmap includes delivering blades with Intel® Xeon® processors for the HP Superdome 2 enclosure (code name “DragonHawk”) and the scalable c-Class blade enclosures (code named “HydraLynx”), while fortifying Windows® and Linux environments with innovations from HP-UX within the next two years.
