Access "Shared file systems: a mixed blessing "

Published: 16 Oct 2012

Seamless, consolidated and efficient management of storage through an advanced shared file system has long been a promise of storage area networks (SANs). Shared file systems--which let hosts share files on a SAN--promise to simplify the management of storage and save money by consolidating storage resources. So, how close are we to that dream? The short answer: There's some progress to report, but to date, not many companies have employed shared file systems. If you have multiple hosts that need to access a common set of files on a SAN, a shared file system is necessary to coordinate between those hosts. Otherwise, if two systems try to read and write from the same file, it's likely that data corruption will occur. A shared file system coordinates access to a file, and ensures that reads and writes are consistent between the hosts. And if the two hosts use different operating systems, you'll also need a shared file system to handle normalizing file operations between multiple operating systems.

What's Inside

    • Storage spending continues to rise by Mark Schlack

      Our extensive survey of 2003 spending plans show spending is up, but storage managers want more than just raw capacity.

    • Shared file systems: a mixed blessing by Benjamin Kuo

      Shared file systems promise to simplify managing storage. But you might have to wait a few years before that promise is fulfilled.

    • ATA Drives Move Up the Ranks

      The nod has been given to ATA drives by EMC, which is now giving customers the option of buying disk array enclosures (DAEs) for their Clariion CX400 and CX600 arrays equipped with ATA, rather than the usual Fibre Channel drives.

    • SRM Software Players Cook Up New Pricing Models

      As more IT shops deploy networked storage, many storage resource management (SRM) vendors are moving to capacity-based pricing, rather than the server- or processor-based pricing models of old.

    • EMC/Accenture Partnership Bears Few Fruit

      Ever wonder whatever became of EMC's ISC, the "vendor neutral" storage consulting service the company launched with Accenture last summer?

    • The shape of the new data center by John R. Blackman

      The key to the next wave of data center technologies is adaptability. Realizing that goal may rest in your hands.
