Hardware Platform Interface - HPI Implementations

HPI Implementations

Several widely-deployed implementations of the HPI specification have been produced, most notably by platform vendors that build AdvancedTCA computer systems or other high-availability computer platforms. In most implementations the HPI Application Program Interface itself is provided through a library that is linked to application programs. This library module typically communicates to an HPI Server running as a daemon process, which performs the functions of the HPI Domains and Resources, communicating with an underlying management infrastructure as required.

Several HPI implementations are based on an open-source implementation of the HPI specification, called OpenHPI. OpenHPI also follows the general design shown in Figure 6, in that it includes a library module that links with application programs and a daemon module to which the library modules communicate. The OpenHPI daemon process is designed to integrate with one or more plug-in modules, which handle the downstream communication with various platform management infrastructures.

The SA Forum Implementation Registry is a process that enables implementations of the SA Forum specifications to be registered and made publicly available. Membership is not required to register implementations. Implementations that have been successfully registered may be referred to as “Service Availability Forum Registered.”
