Example 2: ILM rules and policy for EC object size filtering

You can use the following example rules and policy as starting points to define an ILM policy that filters by object size to meet recommended EC requirements.

CAUTION:
The following ILM rules and policy are only examples. There are many ways to configure ILM rules. Before activating a new policy, simulate the proposed policy to confirm it will work as intended to protect content from loss.
  1. ILM rule 1 for example 2: Use EC for all objects larger than 200 KB
    This example ILM rule erasure codes all objects larger than 200 KB (0.20 MB).
  2. ILM rule 2 for example 2: Make 2 copies
    This example ILM rule creates two replicated copies and does not filter by object size. This rule is the second rule in the policy. Because ILM rule 1 for example 2 filters out all objects larger than 200 KB, ILM rule 2 for example 2 only applies to objects that are 200 KB or smaller.
  3. ILM policy for example 2: Use EC for objects larger than 200 KB
    In this example policy, objects larger than 200 KB are erasure coded, and any other objects that are smaller than 200 KB are replicated using the default catch-all Make 2 Copies rule.
