The document discusses storage options in Linux including the Logical Volume Manager (LVM) and software RAID. It provides an overview of LVM concepts such as physical volumes, volume groups, logical volumes, and commands. It also covers Linux software RAID using mdadm and shows an example mdstat output. Finally, it demonstrates how to set up a storage configuration with both LVM and software RAID along with relevant links for further information.

Agenda:
Have you ever wondered what happens when the kernel fires up? What is going on under the hood before init process is executed?
This talk will go into great depths explaining the entire process. From linker tricks and init sections to mounting and locating the init process to execute.
Speaker:
Boaz Taitler, experienced kernel developer.
This is to introduce the related components in SUSE Linux Enterprise High Availability Extension product to build High Available Storage (ha-lvm/drbd/iscsi/nfs, clvm, ocfs2, cluster-raid1).
Linux memory consumption - Why memory utilities show a little amount of free RAM? How does Linux kernel utilizes free RAM? What is the real amount of free RAM in the system?
Continguous Memory Allocator in the Linux KernelKernel TLV
Agenda:
Continguous Memory Allocator - how to allocate large continguous memory for large scale DMA in the kernel.
Speaker:

VMworld 2017 - Top 10 things to know about vSANDuncan Epping
In this session Cormac Hogan and I go over the top 10 things to know about vSAN. This is based on two years of questions/answers from our field and customers. Useful for any VMware vSAN customer!
#STO1264BU #STO1264BE
Data deduplication is a hot topic in storage and saves significant disk space for many environments, with some trade offs. We’ll discuss what deduplication is and where the Open Source solutions are versus commercial offerings. Presentation will lean towards the practical – where attendees can use it in their real world projects (what works, what doesn’t, should you use in production, etcetera).
Using Linux OS stack to transform your Linux Mission Critical Applications into the Active-Active Stretched Cluster Storage with the very high performance NVMe-oF protocol. The slide deck also illustrates various failure scenarios at Networking and Storage levels, down to the very details of how Cluster RAID1 behave in those failure cases.
In a traditional Xen configuration domain 0 is used for a large number of different functions including running the toolstack(s), backends for network and disk I/O, running the QEMU device model instances, driving the physical devices in the system, handling guest console/framebuffer I/O and miscellaneous monitoring and management functions. Having all these functions in one domain produces a complex environment which is susceptible to shared fate on the failure of any one function, has complex interactions between functions (including resource contention) which makes it difficult to predict performance, and has limited flexibility (such as requiring the same kernel for all device drivers).
""Domain 0 disaggregation"" has been discussed for some time as a way to break out domain 0's functions into separate domains. Doing this enables each domain to be tailored to its function such as using a different kernel or operating system to drive different physical devices. Splitting functions into separate domains removes some of the unintentional interactions such as in-domain resource contention and reduces the system impact of the failure of a single function such as a device driver crash.
Although domain 0 disaggregation is not new it is seldom used in practise and much of its use is focussed on providing enhanced security. Citrix XenServer will be moving towards a disaggregated domain 0 in order to provide better security, scalability, performance, reliability, supportability and flexibility. This talk will describe XenServer's “Windsor” architecture and explain how it will provide the above benefits to customers and users. We will present an overview of the architecture and some early experimental measurements showing the benefits.
Building a Distributed Message Log from ScratchTyler Treat
Apache Kafka has shown that the log is a powerful abstraction for data-intensive applications. It can play a key role in managing data and distributing it across the enterprise efficiently. Vital to any data plane is not just performance, but availability and scalability. In this session, we examine what a distributed log is, how it works, and how it can achieve these goals. Specifically, we'll discuss lessons learned while building NATS Streaming, a reliable messaging layer built on NATS that provides similar semantics. We'll cover core components like leader election, data replication, log persistence, and message delivery. Come learn about distributed systems!
Swift Install Workshop - OpenStack Conference Spring 2012Joe Arnold
OpenStack Swift is a highly-available distributed object storage
system which supports highly concurrent workloads. Swift is the
backbone behind Cloud Files, Rackspace's storage-as-a-service
offering.
In this workshop, which will be hosted by members of SwiftStack, Inc.,
we'll walk you through deployment and use of OpenStack Swift. We'll
begin by showing you how to install Swift from the ground up.
You'll learn:
- what you should know about Swift's architecture
- how to bootstrap a basic Swift installation
After that, we'll cover how to use Swift, including information on:
- creating accounts and users
- adding, removing, and managing data
- building applications on top of Swift
Bring your laptop (with virutalization extensions enabled in the BIOS)
and we will walk through setting up Swift in a virtual machine. We'll
also build an entire application on top of Swift to illustrate how to
use Swift as a storage service. This is a workshop you won't want to
miss!
Kernel Recipes 2015: Linux Kernel IO subsystem - How it works and how can I s...Anne Nicolas
Understanding how Linux kernel IO subsystem works is a key to analysis of a wide variety of issues occurring when running a Linux system. This talk is aimed at helping Linux users understand what is going on and how to get more insight into what is happening.
First we present an overview of Linux kernel block layer including different IO schedulers. We also talk about a new block multiqueue implementation that gets used for more and more devices.
After surveying the basic architecture we will be prepared to talk about tools to peek into it. We start with lightweight monitoring like iostat and continue with more heavy blktrace and variety of tools that are based on it. We demonstrate use of the tools on analysis of real world issues.

Bringing up Android on your favorite X86 Workstation or VM (AnDevCon Boston, ...Ron Munitz
My session at AnDevCon Bostong, May 2013, Boston, MA.
This class introduces the concepts of AOSP and how to use it in order to configure and build one of the most popular Android devices available: The Android emulator, for an x86 target. You will then learn a reincarnation of the AOSP, intended to bring Android to as many x86 devices as possible. You will see its structure and compare it with the AOSP, and demonstrate how such a build works within Virtual Box, QEMU and more.
LEVEL: Intermediate
TOPIC AREA: Embedded Android
