HP Integrity HP Integrity is a family of server and workstation platforms introduced by Hewlett-Packard in the early 2000s built around the Itanium processor architecture originally developed by Intel Corporation in partnership with Hewlett-Packard. Designed to support enterprise-class mission-critical workloads, Integrity systems combined hardware features from Digital Equipment Corporation's legacy with HP engineering to target customers running Oracle Database, Microsoft Windows Server, SUSE Linux Enterprise Server, and HP-UX applications in large data center deployments.
Integrity systems were positioned as high-availability, scalable platforms for transaction processing, database consolidation, and virtualization. HP marketed Integrity alongside its ProLiant and BladeSystem lines, emphasizing integration with OpenVMS heritage clustering concepts from Digital Equipment Corporation and enterprise software stacks from vendors such as Oracle Corporation, Microsoft, SAP SE, and VMware. The product family spanned rack-mounted and blade servers aimed at industries including finance, telecommunications, healthcare, and government agencies like United States Department of Defense contractors and international banking groups.
Integrity servers used the Itanium series of processors developed by Intel Corporation and featured multi-socket designs for scale-up performance. System architecture incorporated large memory capacities with DDR memory modules, advanced I/O fabrics including PCI Express and InfiniBand interconnects, and hardware resilience through redundant power supplies and hot-swappable components. Firmware and system management relied on platform controllers influenced by Digital Equipment Corporation designs and integrated with HP Systems Insight Manager and OpenView-style management ecosystems. High-end models included features such as advanced error-correcting code (ECC) memory, hardware partitioning, and support for symmetric multiprocessing (SMP) configurations used in enterprise virtualization scenarios.
HP certified Integrity platforms for a range of enterprise operating systems including HP-UX, OpenVMS, Microsoft Windows Server 2008 R2, and distributions of Linux such as Red Hat Enterprise Linux and SUSE Linux Enterprise Server. Major independent software vendors (ISVs) provided certified builds for databases and middleware: Oracle Corporation supported Oracle Database on Integrity, IBM-branded middleware products were ported where relevant, and SAP SE offered certified application stacks. The ecosystem also encompassed virtualization and clustering technologies from VMware, HP's own Virtual Connect and Partitioning tools, and backup solutions from vendors like EMC Corporation and Symantec.
Application development for Integrity platforms leveraged compilers and toolchains produced by Intel Corporation (Itanium compilers), HP's own compilers for HP-UX, and open-source toolchains such as GCC and GNU Binutils for Linux ports. Performance tuning used profilers and trace tools from companies like Intel and HP Labs projects, while system-level debugging involved vendors' tools including GDB ports and proprietary debuggers provided with HP-UX development suites. Porting enterprise applications often required adaptation to EPIC architecture characteristics associated with Itanium cores and coordination with ISVs such as Oracle Corporation, Microsoft, and SAP SE to certify binaries for production use.
The Integrity line emerged after Hewlett-Packard acquired Compaq in 2002 and integrated technology from Digital Equipment Corporation, formalized in HP's 2003-2004 product introductions. Early models replaced PA-RISC-era servers and competed with RISC and x86-64 platforms from Sun Microsystems, IBM, and Dell Technologies. Over the 2000s HP expanded the family with multiple form factors and increasing Itanium core counts as Intel released successive Itanium generations. During the 2010s the industry saw reduced momentum for Itanium; Oracle Corporation's 2011 decision to de-support Itanium drew attention, while HP continued to offer Integrity systems and support agreements. Intel later announced end-of-life plans for Itanium, and HP revised its enterprise roadmap to emphasize x86-64 and ARM alternatives across its server portfolio.
Integrity servers were received as strong choices for legacy mission-critical workloads where ISV certification, HP support contracts, and high availability mattered; enterprise customers in banking, telecom, and large-scale ERP deployments often valued the validated stacks. Critics noted limited ecosystem breadth compared with x86-64 platforms from Dell Technologies and IBM Power Systems, and price/performance trade-offs relative to Intel Xeon-based servers. Analyst firms such as Gartner and IDC tracked Itanium platform share and observed gradual market contraction as enterprise virtualization and commodity hardware trends accelerated adoption of x86-64 servers and cloud providers like Amazon Web Services and Microsoft Azure expanded services.
Although Itanium and Integrity hardware waned, the platforms influenced modern server design in areas of high-availability engineering, firmware management, and enterprise certification practices. Concepts from the Integrity family informed HP's later convergence strategies in Converged Infrastructure and influenced system management in successor HP product lines. The engineering collaboration between Hewlett-Packard and Intel Corporation provided lessons for processor–vendor partnerships affecting later architectures in ARM server initiatives and x86-64 ecosystem alignment with ISVs such as Oracle Corporation and Microsoft.
