HP Integrity Servers

HP Integrity 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).

HP retired its Netserver brand in favor of the ProLiant brand.The brand is currently marketed by Hewlett Packard Enterprise. HP ProLiant systems led the x86 server market in terms of units and revenue during first quarter of 2010


HP supports the Windows Server, HP-UX 11i, OpenVMS, NonStop, Red Hat Enterprise Linux and SUSE Linux Enterprise Server operating systems on 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. 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 are the zx2 and sx2000 respectively.

Entry-level servers

1.rx1600 series : 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.

The series support five operating systems:

3.rx2800 series

The 2U rx2800 i2 server used the Intel Itanium 9300 series chipset with 8, 4 or 2 processor cores available. Among features common for the series:

  • Support for up to 24 DIMMs
  • HP p410i 3 Gb SAS Controller
  • Support for 8 hot-plug Serial Attached SCSI (SAS) small form factor (SFF) 2.5 inch drives
  • Quad port 10/100/1000 Base TX LAN
  • Six expansion slots

The series supports three operating systems: HP-UX 11i v3, OpenVMS v 8.4 for Itanium, and Windows Server for Itanium.Related image


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.

Optional features:

  • up to 8 SAS disk drives, with support for up to 72 GB 15K-RPM or 146 GB 10K-RPM disks.
  • Redundant hot-swappable power supply
  • 8-port HP Smart Array P400 or P600, or 16-port P800 SAS RAID controllers available for internal disks, supporting RAID 1/5/6 and hot spare disks.

5.rx4600 series

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. 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.
