The future is already here !
In fact here ! This is a new specification which is gaining traction to allow hardware configuration of systems through a RESTful interface. All new HP ProLiant Gen9 servers from HP are providing a first version of what is not yet the standard, but looks very near to it, and provide already a rich interface.
This is pretty exciting, as it will allow people like me working on Disaster Recovery e.g., or people like Devananda van der Veen who is the Ironic PTL (OpenSTack bare metal deployment component) or many others to have, when it’s ready, a single interface to configure the servers from different manufacturers following the Redfish Specification (as of now HP, Dell, Emerson, Intel). And it’s much more feature rich than IPMI, so you would be able to go well farer with it and reach a real Software Defined Compute node.
In order to make it usable for Ironic we’ve started to work on a low level python library (python-redfish) on which we’ll be able to build the Ironic driver for Redfish later on. This is work for Liberty and after of course. And as Ironic can be also use alone, I’m more and more thinking of using it as a way to provide MondoRescue images for bare metal deployment as an additional feature over media boot. Especially if there are plans to have a standalone web interface for Ironic !
If you want to learn more on the HP implementation of the RESTful API, there is a webinar organized Wednesday, April 29, 2015 from 10:00 am CDT to 11:00 am CDT. Register from https://h71044.www7.hp.com/campaigns/2013/events/linkandcoordinate/index.php
And if you want to learn a bit more of where we are on this, read the code (easy for now) or come at Vancouver for the upcoming OpenStack Summit to discover it.
