What is Ironic ?

● Hope you attended Devananda van der Veen's presentation

– http://sched.co/2qb4

– https://github.com/devananda/talks/blob/master/isnt-it-ironic.html

● Ironic is the OpenStack bare-metal deployment project – Usable as a Nova driver or Standalone with Kilo

– Provides common API across HW vendors and physical/virtual resources

– Uses drivers to abstract interactions with HW

What is Redfish ?

● A DMTF standardisation effort

– HW Management REST API specification proposal (v0.96.0a) – DSP0266

– JSON and XML (Odata CSDL) based Schemas – DSP8010

– Mockups to be integrated in an existing web server to simulate a Redfish system– DSP2043

– Available at http://www.dmtf.org/standards/redfish

– Initially promoted by Dell, Emerson, HP and Intel

● In simpler terms ?– This is an IPMI replacement

– This is a way to get and set HW configuration items on physical platforms using a RESTful API

– The future management path of most platform

http://www.dmtf.org/standards/redfish

7


Why Redfish ?

● Security

– Uses known and widely used methods (https, RESTful API)● Better HW description

– Notions of Chassis (Blades), Multi-Node platforms (such as Moonshot)● Supports Manufacturer extensions

– Like SNMP via private extensions described in additional schemas● Standard across different manufacturer

– Ease management at scale for heterogeneous environments

– Tool or Tool-less access possibilities

8


Why combining Ironic and Redfish ?

● DMTF should publish Redfish 1.0 in June 2015

– Will increase adoption (already 50%+ of servers)

– Provides iLO type of features in a standard way● Ironic is the bare-metal deployment project of OpenStack

– Could benefit from Redfish existing features (virtual media, power management, PXE boot)

– Could benefit from Redfish future features (HTTP Boot)● Ironic can be used standalone

– Ease testing procedure

– Combination used by other tool sets

9


How to combine Ironic and Redfish ?

● First develop a python-redfish module

– Provides all the features needed by Ironic (power management, inventory, ...)

– Use the DMTF mockups to test the features (easy even without HW)● Ironic already has drivers for BMCs

– ILO, IPMI

– Create a Redfish driver, using the previous python-redfish module, based on the iLO one

● Create a standalone test environment based on Docker

– A Container for running Ironic standalone

– A Container for emulating a Redfish based platform

– A series of test to activate the combination at software level.

Discussions for the Design Summit

● Interaction with CMDBs

– Ironic manages a part of inventory

– Using Redfish this could be automated via an ironic-inventory module (e.g.)● ironic inventory -d redfish -i redfish_username=admin -i redfish_password=fake

-i redfish_address=10.1.2.3 -n mytest● If tuple (?) already exists does a node-update, if not does a node-create and port-

create– Ironic-inventory could be run by cron to re-check the content on a regular basis

● ironic inventory –all|-a● ironic inventory –uid ironic-node-uuid

– Ironic-inventory could also be used to fill a CMDB with details on a configuration item and extended to give back all details needed.

– Combined solution with a CMDB such as iTop is an full Open Source SDI one
