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.
1.3.1 HPI 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:
z Single shelf library
z Multi shelf library
