HP NonStop (HPE) fault tolerant servers originally developed by Tandem Computers – Summary

My IT career between the years 1990 and 2014, involved significant programming and large projects for Tandem HP NonStop servers.

HP NonStop Tandem Computers

HP NonStop refers to the line of fault-tolerant servers and software originally developed by Tandem Computers and now owned by Hewlett Packard Enterprise (HPE). These systems are designed for continuous operation and uninterrupted transaction processing by using redundant hardware components and independent processors to automatically failover in the event of a failure, ensuring high availability for critical applications in banking, telecommunications, and healthcare. 

Origins and Evolution

  • Tandem Computers: Founded in 1974, Tandem introduced the NonStop system, a pioneering fault-tolerant computer with no single point of failure, revolutionizing continuous availability for online transaction processing. 
  • Acquisitions: Tandem Computers was acquired by Compaq in 1997, and Compaq was later acquired by Hewlett-Packard (HP) in 2001. 
  • Current Ownership: After the split of HP into Hewlett Packard Enterprise (HPE) and HP Inc. in 2015, the NonStop product line became part of HPE. 

Key Features and Uses

  • Fault Tolerance: The systems are built with redundant components, including identical processors and storage devices, allowing them to automatically detect and recover from hardware or software failures without interruption. 
  • High Availability: This fault-tolerant architecture is ideal for mission-critical applications that require constant uptime, such as financial transactions, emergency services, and large-scale banking systems. 
  • Scalability: NonStop systems are designed for scalability, able to handle large commercial workloads by adding independent processors. 
  • Dedicated Operating System: Historically, NonStop systems ran on proprietary software like the Guardian operating system and used the TAL programming language
  • Specialized Database: The line includes NonStop SQL (currently SQL/MX), a relational database designed for the high availability and scalability needs of these systems.

    My ‘A’ Level Computing Project was developed on a Amstrad PC 1512 and was written in Turbo Pascal. The software provided a means for a local town newspaper to store, track and calculate the money payable to delivery staff based on paper round metrics. These metrics related to size of round, papers delivered and any leaflets attached to a delivery for that week. 

    My ‘O’ Level Computing Project was developed on a LINK 480Z Research Machine and was written in Extended BASIC. Three submissions were required with appropriate design and testing. The excerpts here show details of a BASIC program for storing and displaying student exam results.

    Leigh College, Marshall Street, Leigh. WN7 4HX – Timeline History from 1966

    The Leigh College old building on Marshall Street was an iconic piece of the town’s educational landscape that stood for 41 years before being replaced by modern facilities.

    Chronological Timeline

    • 1966: The Marshall Street campus building is officially constructed and opened, initially serving the local education system as the area transitioned away from traditional grammar schools.
    • 1976: Leigh College officially begins its primary era at the Marshall Street building following major local secondary and further education restructuring.
    • 1985–1988: The building serves a generation of A-Level and vocational students with highly regarded local facilities, though the physical structure begins to show its age.
    • 1992: Leigh College amalgamates with the Wigan College of Technology to form Wigan and Leigh College. The Marshall Street building remains open as a primary Leigh-based campus alongside the Railway Road site.
    • 2002: The Learning and Skills Council (LSC) approves a series of radical redevelopment plans due to the increasingly poor, outdated condition of the Marshall Street accommodation.
    • 2003–2004: Major plans for the £75 million Leigh Sports Village are finalized and approved. The project officially designates a new, modern location for the Leigh campus, sealing the fate of the Marshall Street building.
    • 2007: The gates close for the final time on August 1, 2007. The 600 remaining sixth-form and adult students are relocated to the brand-new, three-story facility at the Leigh Sports Village. Later that year, the 41-year-old old building is completely demolished.

    • 2026: A 50th-anniversary reunion and a dedicated local history project are organized by local historians to commemorate the 1976 launch of the Marshall Street college era.
