  • Service Availability Interface


This chapter reviews the two leading open source implementations of the Service Availability Forum (SAF) Service Availability Interface specifications: OpenHPI, which implements the Hardware Platform Interface (HPI), and OpenSAF which delivers the services of the SA Forum Application Interface Specification (AIS). The chapter takes a detailed look at each of these open source projects. It first describes the architecture and codebase of OpenHPI project. The chapter then describes the architecture and the main implementation aspects of OpenSAF, as well as management aspects of OpenSAF and process illustrating deployment of OpenSAF on target environments. Finally, the chapter provides some background information on how the project came about and the evolution of the middleware implementations up until latest stable version.
