iLO Power Driver for Ironic¶
This proposal adds the ability to manage power control for HP ProLiant servers via iLO using iLO client python library.
The HP iLO subsystem is a standard component of HP ProLiant servers that simplifies initial server setup, server health monitoring, power and thermal optimization, and remote server administration. Our proposed Ironic IloDriver will expose these capabilities in OpenStack to manage HP Proliant servers.
This proposal covers support for power management interfaces using iLO.
To add a new IloPower() module which will conform to base.PowerInterface. This module uses iLO credentials (ilo_address, ilo_username, ilo_password), specified in driver_info property of the node to connect to target iLO. It makes use of iLO client in proliantUtils library to talk to iLO.
HP iLO also supports more advanced power management features for monitoring and power capping. We would like to add support for these advanced vendor specific features later on.
NOTE: Even though iLO uses SSL over port 443 for communication, ssh key based authentication is not supported for RIBCL communication. iLO username/password will need to be provided for talking to iLO.
IPMI standard specification can be used for the power management. But adding a new power module allows the solution to be consistent with other future iLO drivers for deploy, management in using a single iLO interface to do the operations.
There is no functional benefit as of now in choosing this module over IPMI.
Data model impact¶
REST API impact¶
Driver API impact¶
Nova driver impact¶
iLO admin credentials will be stored unencrypted in the Ironic DB. This will also be visible with the driver_info of the node when a node-show is issued. But only the ironic admin user will have access to the Ironic DB and node details.
Other end user impact¶
Other deployer impact¶
- The following driver_info fields are required:
ilo_address- hostname or IP address of the iLO.
ilo_username- the username for the iLO with administrator privileges.
ilo_password- the password for
ilo_client_timeout- the timeout for iLO operations. The default value will be 60 seconds.
ilo_client_port- the port to be used by iLO client for iLO operations. The default value will be 443.

Implement a new power module, IloPower, conforming to base.PowerInterface.
This feature is targeted for HP ProLiant servers with iLO4 and above. This power module might work with older version of iLO (like iLO3), but this will not be officially tested by the iLO driver team.
Depends on proliantutils library.
Unit tests will be added, mocking proliantutils library.
Tempest tests will be considered later when more advanced module of IloDriver like deploy are available in the ironic tree.
The required driver_info properties need be included in the documentation to instruct operators how to use iLO Driver with Ironic.
