1.3 Architecture
The Artesyn HPI implementation is provided in the form of a client-server architecture. In the
Centellis 4620/4440 system environment the server, called HPI daemon, runs on the ATCA-
F125/F140 switch blade, and the client, which is constituted by an HPI library and an
application which links that library, runs on any node within a shelf. Internally each HPI daemon
is connected to a Shelf 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.
