Container Management APIs: An Overview - Serge Hallyn, Canonical
Several popular container managers currently exist, including lxc, openvz, libvirt, and docker. These use APIs from different underlying libraries to drive containers. Power users of the container managers will frequently benefit from knowing how to use the underlying APIs themselves, whether to drive testsuites or provide new functionality.

Container Mechanics in rkt and Linux - Alban Crequy
Linux containers as a virtualization solution are becoming more prevalent. An example of a container solution is rkt, whose development started end of 2014. Under the hood, container software on Linux uses the same cgroups and namespaces API. Both container software and kernel code for containers continue to be developed.

Alban will first describe the Linux API that make containers possible: namespaces and cgroups. Then he will explain how rkt containers use this Linux API.

A Simple, and Scalable pNFS Server For Linux - Christoph Hellwig
The parallel NFS extensions in NFSv4.1 have seen far less deployment than the hype around them would suggest. One big reason for that is few usefulservers have been available, and the other one are over complicated specification that are almost unimplementable.

This presentations explains the high level concepts of pNFS, and their heritage. It continues with a detailed explanation of a Linux Kernel implementation of the pNFS block layout server, which has been kept very simple and small despite the protocol challenges.

Christoph Hellwig has been working on Linux Storage and File system projects for 15 years. He works all the way up and down the Storage and File system stack, and runs a business focused on Linux Storage architecture and training.

Challenges in Distributed SDN - Duarte Nunes, Midokura and Guillermo Ontañón, Midokura
Virtual software-defined networking (SDN) is becoming one of the most interesting and appealing topics in our industry. This talk will cover the challenges of scalability that cloud-scale, distributed virtual SDN solutions face. Duarte and Guillermo will go over the gory details of hardening distributed ARP tables and of replicating the NAT state of distributed routers, all the while ensuring packets are processed at ludicrous speed. The talk will cover the problem space, what tradeoffs are involved, and how these issues are solved in Midonet, an open source network virtualization system.

Open-Channel Solid State Drives - Matias Bjørling, CNEX Labs
This presentation gives an introduction to Open-Channels SSDs and LightNVM - the kernel subsystem created to support Open-Channel SSDs. Open-Channel SSDs allow applications to directly control data placement and garbage collection within SSDs. The benefits are consistent latency and throughput in high-performance workloads and extending SSD lifetime. The main objective of this talk is to show the possibilities of this new storage interface, report on current application developments, the current status of LightNVM, and present the development roadmap for both upcoming kernel functionality and user space support.
