File Systems: The state of the art

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 ...

    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.

  • Easing away from ESCON

    by  Alex Barrett

    ESCON, the protocol that pre-dated FICON as a systems-to-storage connection, is incompatible with the newer FICON-based systems. This tip looks at various ways you can tackle this dilemma.

  • 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.
