Three ways to create clustered storage

Clustered storage systems run on storage servers, NAS gateways and hosts. Here's how to determine which clustered file-system architecture is best for your needs and storage environment. Clustered file systems (CFS) offer a practical way to respond to big storage problems such as the proliferation of low-cost servers, application data growth and the need to deliver better application performance. A CFS pulls together and shares the excess storage capacity that's often available but hidden on storage networks. In doing so, a CFS increases storage utilization rates, delivers performance typically found only in high-end arrays and gives users an economical way to scale their architectures. There are three ways to deploy a CFS: on storage servers, NAS gateways and hosts. Any server in the cluster can access any block of storage managed by the cluster. Most CFS also integrate the volume manager with the file system. This allows the CFS to break large files into blocks called extents, and to stripe those extents across different ...

Features in this issue

  • Tricky backup for SharePoint

  • CDP: Look before you leap

    Some pundits have postulated that continuous data protection (CDP) will replace backup. But is that just new technology hyperbole or is CDP a must-have technology?

  • Backup-to-disk performance tuning

    Disk-based backup can lower costs, reduce complexity and add scalability. But to achieve top performance, you'll need to do lots of benchmarking and watch for poorly configured production storage.

Columns in this issue

  • Backup best practices are always evolving

    Some new advances in backup, such as virtual tape libraries, represent evolutionary enhancements to the traditional backup process, while others like continuous data protection and single-instance storage are potentially far more transformational.

  • 10 points to consider before deploying an e-mail archive

    Selecting an e-mail archiving application based solely on features and functions may result in unexpected administration costs. Consider these 10 points before deploying an e-mail archiver.

  • Some small tech upstarts might play big roles

    Storage Bin: The big storage vendors are always trying to steal a piece of each other's pie. But some small tech upstarts might play big parts in determining who comes out on top.
