Access "File Systems: The state of the art"

Published: 19 Oct 2012

New file systems are solving some of the biggest storage system problems, such as scaling and performance. For most of their relatively brief history, file systems have traveled below the radar, performing yeoman tasks. Nowadays, instead of being the unsung workhorses of the infrastructure, some file systems have achieved a higher profile and are home to some of the most cutting-edge innovation in data storage. The change comes from a number of startups and established companies using advances in file-system technologies to solve some large, lingering problems such as quick I/O reads and writes, file locking and synchronization, support for geographically dispersed work groups and NAS consolidation. New file systems are the underpinnings of the following storage technologies: High-performance clusters. The challenge of high-performance computing (HPC) has been to assemble hundreds or thousands of small compute nodes into an efficient, parallelized computing resource. At the core of this massive effort are file-system technologies that federate the ... Access >>>

What's Inside

Features
    • The lowdown on replication appliances

      Operating system- and storage array-agnostic, replication appliances give companies increased flexibility to address one-time and continuous data replication needs, while allowing applications to continue processing without data loss or to recover with minimal downtime.

    • Backup outsourcers think small

    • Storage salaries increase

      The results for Storage's annual salary survey are in and storage professionals report salary growth. While the increases over last year are modest, they do represent the third straight year that our exclusive survey has shown an increase in storage salaries.

    • File Systems: The state of the art by Brad O'Neill

      Generally overlooked, file systems are assuming a prominent place at the heart of new technologies that address some of the most vexing storage problems, such as scaling and performance. New file-system approaches provide the underpinnings for technologies such as clustering, global namespaces and wide-area computing.

    • Quality Awards: What are the best midrange arrays?

      Midrange array users are a generally satisfied group, according to the latest Diogenes Labs-Storage magazine Quality Awards survey. While all midrange array vendors fared quite well in this third installment of our awards program, the vendor that snared top honors might surprise some people.

    • Secure your backups

      The headlines tell the story: Lost tapes can jeopardize the confidentiality of personal information and cause public-relations woes for those companies charged with safeguarding that data. Encryption can solve the problem, but implementing tape encryption isn't so easy, as performance issues could impact backup windows.
