OpenHPI is an open source project created with the intent of providing
an implementation of the SA Forum's Hardware Platform Interface (HPI).
HPI provides an abstracted interface to managing computer hardware,
typically for chassis and rack based servers. HPI includes a resource
modeling; access to and control over sensor, control, watchdog, and
inventory data associated with resources; abstracted System Event Log
interfaces; hardware events and alerts; and a managed hotswap
interface.

OpenHPI provides a modular mechanism for adding new hardware and device
support easily. Many plug-ins exist in the OpenHPI source tree to
provide access to various types of hardware. This includes, but is not
limited to, IPMI based servers, Blade Center, and machines that export
data via sysfs. For up-to-date status on these components, check out
