HPE Integrity Servers
HPE Integrity Servers is a series of server computers produced from 2003 onwards by Hewlett Packard Enterprise (formerly Hewlett-Packard), and based on the Itanium processor. The Integrity brand name was inherited by HP from Tandem Computers via Compaq.
In 2015, HP released the Superdome X line of Integrity Servers based on the x86 Architecture. It is a 'small' Box holding up to 8 dual Socket Blades and supporting up to 16 processors/240 cores (when populated with Intel Xeon E7-2890 or E7-2880 Processors).
HPE discontinued support for the final Integrity server models at the end of 2025, along with the associated HP-UX operating system.
Over the years, Integrity systems have supported Windows Server, HP-UX 11i, OpenVMS, NonStop, Red Hat Enterprise Linux and SUSE Linux Enterprise Server operating systems on Integrity servers. As of 2026, OpenVMS is the only operating system for Integrity servers which still receives active support.
Early Integrity servers were based on two closely related chipsets. The zx1 chipset supported up to 4 CPUs and up to 8 PCI-X busses. They consisted of three distinct application-specific integrated circuits; a memory and I/O controller, a scalable memory adapter and an I/O adapter. The PA-8800 and PA-8900 microprocessors use the same bus as the Itanium 2 processors, allowing HP to also use this chipset for the HP 9000 servers and C8000 workstations.
The memory and I/O controller can be attached directly to up to 12 DDR SDRAM slots. If more slots than this are needed, two scalable memory adapters can be attached instead, allowing up to 48 memory slots. The chipset supports DIMM sizes up to 4 GB, theoretically allowing a machine to support up to 192 GB of RAM, although the largest supported configuration was 128 GB.
The sx1000 chipset supported up to 64 CPUs and up to 192 PCI-X buses. The successor chipsets were 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.
