HPE Integrity Servers is a series of server computers produced by Hewlett Packard Enterprise (formerly Hewlett-Packard) since 2003, 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 Integrity Servers

General

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 2020 the operating systems that are supported are HP-UX 11i, OpenVMS and NonStop.

HPE Integrity Servers

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.

HPE Integrity Servers

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.
