Creating an ILM rule

Contributors netapp-lhalbert

ILM rules allow you to manage the placement of object data over time. To create an ILM rule, you use the Create ILM Rule wizard.

Before you begin
  • You must be signed in to the Grid Manager using a supported browser.

  • You must have specific access permissions.

  • If you want to specify which tenant accounts this rule applies to, you must have the Tenant Accounts permission or you must know the account ID for each account.

  • If you want the rule to filter objects on last access time metadata, Last Access Time updates must be enabled by bucket for S3 or by container for Swift.

  • If you are creating replicated copies, you must have configured any storage pools or Cloud Storage Pools you plan to use.

  • If you are creating erasure-coded copies, you must have configured an Erasure Coding profile.

  • You must be familiar with the data-protection options for ingest.

  • If you need to create a compliant rule for use with S3 Object Lock, you must be familiar with the requirements for S3 Object Lock.

Note To create the default ILM rule for a policy, use this procedure instead: Creating a default ILM rule.
About this task

When creating ILM rules:

  • Consider the StorageGRID system's topology and storage configurations.

  • Consider what types of object copies you want to make (replicated or erasure coded) and the number of copies of each object that are required.

  • Determine what types of object metadata are used in the applications that connect to the StorageGRID system. ILM rules filter objects based on their metadata.

  • Consider where you want object copies to be placed over time.

  • Decide which option to use for data protection option at ingest (Balanced, Strict, or Dual commit)

Steps
  1. Select ILM > Rules.

    The ILM Rules page appears, with the stock rule, Make 2 Copies, selected.

    ILM Rules page
    Note The ILM Rules page looks slightly different if the global S3 Object Lock setting has been enabled for the StorageGRID system. The summary table includes a Compliant column, and the details for the selected rule include a Compliant field.
  2. Select Create.

    Step 1 (Define Basics) of the Create ILM Rule wizard appears. You use the Define basics page to define which objects the rule applies to.
