1. File Systems for Data Protection

   4 April 2011

   This tutorial will explain some of the differences between a general purpose file system and a file system designed for data protection.

2. File Systems for Object Storage Devices

   11 October 2010

   Object-based storage devices (OSDs) may well be the 'next big thing' in file-oriented data storage. Already popular in the high-performance computing arena, they are poised to enter more more general enterprise computing environments. By distributing storage management and enabling secure data transfer between storage devices and clients, OSDs promise significant improvements in scaling and administrative simplicity. But making effective use of OSDs requires a new breed of file system - one that makes use of the new devices effectively to deliver the promised benefits.

3. File Systems: What They Are and Why You Care

   11 October 2010

   File systems - the software that transforms bits stored on disks into business objects - are so much a part of the IT landscape that we hardly even notice them. We fire up the computer, and immediately start working with 'folders' and 'files,' without ever reflecting on the complex software that makes it so easy and natural to store and process data electronically. But new requirements and new file system capabilities are making it necessary for decision makers to understand the 'gets' and 'don't gets' of different types of file systems. This tutorial looks inside the file system to describe how it does its magic, explores new and emerging file system capabilities, and addresses the question, 'As an IT decision maker, why do I care what kind of file systems my department is using.'

4. Storage Tiering and the Impact of Flash on File Systems

   11 October 2010

   With all of the talk about how storage systems will be impacted by large amounts of relatively inexpensive Flash little has been said about how file systems will need to change to take advantage of it. This tutorial will cover how file systems are evolving tiered architectures to leverage Flash.

5. The File Systems Evolution

   11 October 2010

   File Systems impose structure on the address space of one or more physical or virtual devices. Starting with local file systems over time additional file systems appeared focusing on specialized requirements such as data sharing, remote file access, distributed file access, parallel files access, HPC, archiving, security etc.. Due to the dramatic growth of unstructured data files as the basic units for data containers are morphing into file objects providing more semantics and feature-rich capabilities for content processing

6. Tiered File System without Tiers

   11 October 2010

   File systems have evolved considerably, yet the vast majority of them are still a simple organizational layer on top of a block device. As the sheer amount of data scales in an organization, it becomes absolutely critical that file systems evolve as well. This presentation focuses on a modern file system which include native tiering capabilities, native per-file performance and protection capabilities, and advanced scalability

7. Aspects of Deduplication

   12 April 2010

   Deduplication can be accomplished in different ways in a file system. This tutorial will focus on block-level deduplication. While conceptually simple, an implementation can be quite complex as it must address multiple issues: scalability - when the lookup table no longer fits in memory. performance - impact of table lookups and writes dependent on reads. space accounting - space now be shared between files and file systems. administrative model - keeping model simple. We will talk about these issues in detail. This tutorial will also cover expanding the notion of deduplication beyond the storage device to include in-memory and over-the-wire deduplication.

8. Scale-Out Storage Systems

   12 April 2010

   This is a overview of scale-out storage systems and their underlying file system technologies - primarily focused on network-attached storage systems. In this presentation, scale-out will be defined in contrast with scale-up storage systems, the market, user, and technology needs driving new class of storage systems will be explained, as well as a survey of open-source and commercial implementations available today.
