Hardware Platform Interface

Hardware Platform Interface

The Hardware Platform Interface (HPI) is an open specification that defines an application programming interface (API) for platform management of computer systems. The API supports tasks including reading temperature or voltage sensors built into a processor, configuring hardware registers, accessing system inventory information like model numbers and serial numbers, and performing more complex activities, such as upgrading system firmware or diagnosing system failures.

HPI is designed for use with fault-tolerant and modular high-availability computer systems, which typically include automatic fault detection features and hardware redundancy so that they can provide continuous Service Availability. Additional features common in hardware platforms used for high-availability applications include online serviceability and upgradeability via hot-swappable modules.

The HPI specification is developed and published by the Service Availability Forum (SA Forum) and made freely available to the public.

Famous quotes containing the words hardware and/or platform:

    “A friend of mine spoke of books that are dedicated like this: “To my wife, by whose helpful criticism ...” and so on. He said the dedication should really read: “To my wife. If it had not been for her continual criticism and persistent nagging doubt as to my ability, this book would have appeared in Harper’s instead of The Hardware Age.””
    —Brenda Ueland (1891–1985)

    “Do you know I believe that [William Jennings] Bryan will force his nomination on the Democrats again. I believe he will either do this by advocating Prohibition, or else he will run on a Prohibition platform independent of the Democrats. But you will see that the year before the election he will organize a mammoth lecture tour and will make Prohibition the leading note of every address.”
    —William Howard Taft (1857–1930)
