System Management Interfaces Overview

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:
 Single shelf library
 Multi shelf library
The single shelf library supports the communication with one HPI daemon only. It is only used
internally, for example by the SNMP subagent and is not intended to be used by user
applications. The multishelf library, on the other hand, supports the communication with one
up to several HPI daemons. This becomes necessary if you wish to deploy redundancy in one
HPI-B based shelf management system or if you wish to manage several shelves. The multishelf
library is the library which you should build your applications on, it is the official interface to
customer applications.
Details about supported combinations of CPU architecture/Linux distribution are given in
Chapter 2, Software Installation and Configuration, on page 19 .
1.3.2 HPI Daemon
The HPI daemon within an Centellis 4620/4440 system runs on the ATCA-F125/F140 blades
and its main tasks are:
 Provide a single access point to control and monitor hardware components in a shelf
 Map information provided by the underlying Shelf Manager to HPI
1.3.3 SNMP Agent
The Artesyn Embedded Technologies HPI-B distribution includes an SNMP agent. It provides a
management interface which allows you to remotely control and manage hardware
components within the Centellis 4620/4440 shelf. The supported Management Interface Base
(MIB) is the standard SAI-HPI-SNMP-B.01.01.mib as defined by the Service Availability Forum.
