Hardware Platform Interface (HPI)  APIs for fine grained low level access to hardware:  Inventory  HPI accessible hardware managed by domains found in –HPI Domain presence table  Within each domain is a Resource Presence Table describing discovered management resources  HPI resource functions  Each resource has a Resource Data Record Repository for each of its managed entities. This RDR contains –Instrument capabilities, inventory data (e.g. manufacturer, serial no, version, asset tag etc)  Instrumentation: – Sensor, Control, Inventory Data Repository, Watchdog Timer, Annunciator (LEDs)  Management Capabilities : –Hot-swap, configuration, load, reset, and power management –Diagnostics and Firmware Upgrade  HPI per domain: events, event logs and alarm table

Application Interface Specification (AIS)  Platform Services  Platform Management service provides a convenient abstraction to monitor state changes in groups of entities comprising hardware, hypervisors and operating systems  A cluster management service that provides a consistent view of the healthy configured nodes in a cluster  Basic management services: Standard interfaces for applications and middleware:  Configuration & runtime management information  Administrative commands  Notification for alarms, state changes, object lifecycle changes, attribute changes and security alarms  Logging of alarms, notifications, system messages and application specific streams  Access security functions for the AIS and HPI services  Frameworks  Availability management of applications and middleware  Software management for managing HW, OS, middleware and application upgrades taking service availability into account  Utility Services provide common services required in distributed HA systems including  Checkpointing, Event distribution, distributed locks, message passing, name lookup and timer services
