Ceph is a mature platform for software-defined storage environments scaling to dozens or hundreds of PetyBytes. However real life implementation, operations and maintenance are complex tasks. Ensuring the right compatibility of software and hardware, avoiding bottlenecks between storage nodes, keeping the complete stack running, exchanging end-of-life hardware and operating the complete stack efficiently may create substantial efforts and risks for IT. Playing around with petabyte-scale storage is no option and reliable service levels are key. Fujitsu presents an easy solution how to move from “Build your own disaster” to an enterprise class service level way of using Ceph based storage.

Oh no! You have a bug in your app, but you have no idea where it is. I’ll walk you through how we found and squashed a gnarly bug in socket.io using wireshark, chrome’s developer tools, lots of logging, and pretty graphs. I’ll also show you some good tips and tricks for tracking down and squashing bugs of your own.
Sass 3.3 is coming soon and there are some amazing new features in it.

Open vSwitch (OVS) is one of the more popular ways to provide VM connectivity in OpenStack. Rackspace has been using Open vSwitch in production since late 2011. In this session, we will detail the challenges faced with managing and upgrading Open vSwitch across a large heterogenous fleet. Finally, we will share some of the tools we have created to monitor OVS availability and performance.
Rackspace's OnMetal launched in July as the first and only deployment of Ironic on the public cloud. Rackspace has since scaled Ironic to manage thousands of servers in a multitenant environment.
This talk will discuss the challenges we faced while deploying and scaling OnMetal. Ironic's architecture allows for a straightforward HA model and horizontal scaling, but there were (as always) performance issues that set our team back while growing our production environment. These issues came to life on both the Nova and Ironic side of the control plane.
This talk will also cover how we brought a new deploy model to Ironic that fixed some core architectural issues with the default deploy driver, while also allowing Ironic to do more interesting things with hardware that it manages.
