Intelligent Platform ManagementInterface

A step to unify light out managementCurrently the only way to manage heterogeneous hardwareAvailable from client tools thanks to toolIPMIutil

Intelligent Platform ManagementInterface

But with some constraintsLow level specificationsHard to use for end usersNot all light out features supported and hard to extendSecurity concernsComplex to manage on high integrated servers

The need for automation / scalability

The need for automation / scalabilityScale out servers architecture with commodity serversRepetitive configurationEnd user friendlyAvailable from anywhere, with any platformSecuritySoftware Defined Infrastructure market trend

Here comes Redfish !

What is RedfishA powerful and user friendly IPMI alternative

Standard proposed by the Distributed Management Task ForceInitially promoted by Dell, Emerson, HP and Intel

Redfish v1.0 (3 Aug 2015)rd

Python Redfish

A python library to manage RedfishOpen source projectInitiated by a small group of people (Bruno, Devenanda, René,Sammer, Vincent)Available at https://github.com/uggla/python-redfish

Python RedfishInitial goals

Provide a library to easily add Redfish support into applicationsProvide a Redfish client tool based on the library

Python RedfishUltimate goals

Integration into Openstack IronicIntegration into CMDB tools (cf project)World domination ! :)

Python RedfishLibrary usage example

Import

Create a redfish object

Retrieve API version

Retrieve power status

import redfish

remote_mgmt = redfish.connect(URL, USER_NAME, PASSWORD, verify_cert=False)

remote_mgmt.get_api_version()

remote_mgmt.Systems.systems_list[0].get_power()

Python RedfishLibrary usage example

Get bios parameter

Set bios parameter

Reboot system

remote_mgmt.Systems.systems_list[0].bios.get_parameter("AdminPhone")

remote_mgmt.Systems.systems_list[0].bios.set_parameter("AdminPhone","xxx")

remote_mgmt.Systems.systems_list[0].reset_system()
