Information lifecycle management for IBM Spectrum Scale

IBM Spectrum Scale™ can help you achieve information lifecycle management (ILM) efficiencies through powerful policy-driven automated tiered storage management. With the ILM toolkit, you can manage sets of files and pools of storage, and you can automate the management of file data.

Using these tools, GPFS™ can automatically determine where to physically store your data regardless of its placement in the logical directory structure. Storage pools, filesets and user-defined policies provide the ability to match the cost of your storage resources to the value of your data.

Note: This feature is available with IBM Spectrum Scale Standard Edition or higher.
GPFS policy-based ILM tools allow you to:
  • Create storage pools to provide a way to partition a file system's storage into collections of disks or a redundant array of independent disks (RAIDs) with similar properties that are managed together as a group. GPFS has three types of storage pools:
    • A required system storage pool that you create and manage through GPFS
    • Optional user storage pools that you create and manage through GPFS
    • Optional external storage pools that you define with GPFS policy rules and manage through an external application such as IBM Spectrum Protect™
  • Create filesets to provide a way to partition the file system namespace to allow administrative operations at a finer granularity than that of the entire file system. See Filesets.
  • Create policy rules based on data attributes to determine initial file data placement and manage file data placement throughout the life of the file. See Policies for automating file management.
