python-redfish reached 0.3, first interesting version for others


Back in 2015, during our internal TES event in Grenoble, a group of people gathered to talk about the new Redfish DMTF standard and how we could add its support into Ironic.

Since that, we have worked first on a new Open Source python library to interact programmatically with Redfish 1.0 based systems.

We tried to promote it during OpenStack Summits but except in Vancouver when I did a short video explaining that, not enough interest from the community. Of course we had very few to show at that time.

One year after, we have now reached version 0.3 of the project. And while that doesn’t sound a lot, in fact the libray is now usable by others to interact with Redfish based systems.

What it provides:

Our next steps are in multiple directions:

Hopefully, as you’re reading this, you’re interested by the topic, and we’d be happy to get your feedback, and more over your patches in order to improve our work, and speed up the development !

And don’t forget the HPE Open Source project available as well on github which provides much more capabilities, due to its support of the iLO and iLOCM extensions to the Redfish standard.

Software Defined Compute: Redfish and Ironic at the next OpenStack Summit


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

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.
