System Management Interfaces Overview	HPI Library

Management Alarm module (SAM) in the shelf. The communication between HPI daemon and SAM is realized via RMCP (Remote Management Control Protocol) which is an IP- encapsulation of IPMI commands. The communication between HPI daemon and HPI client is realized by an IP-based remote HPI communication protocol.

An HPI client may access one or more HPI daemons, and on the other hand, an HPI daemon may be accessed by one or more HPI clients. The following figure illustrates this.

1.3.1HPI Library

The HPI library is the primary user interface. It is intended to be used by applications that wish to control and monitor HPI managed components, such as ATCA shelves, blades and other FRUs. The HPI library is delivered as shared and as static library and has to be linked with an application.

There are two types of HPI libraries available:

zSingle shelf library

zMulti shelf library
