About SmartIO caching for databases on VxVM volumes

SmartIO provides application templates to optimize caching for databases running on VxVM volumes. SmartIO uses the templates to apply policies to particular types of volumes in the database. For example, index volumes may have different caching policies from data volumes.

SmartIO provides the following application templates for VxVM volumes:

  • Template name: oracle

    Optimizes caching for Oracle databases running on VxVM volumes.

  • Template name: sybase

    Optimizes caching for Sybase databases running on VxVM volumes.
