    Hi
      Lindsay,

      
      Volume level data tiering was made fully supported in latest 3.7
      releases, though an active effort is still going on to increase
      the small file performance. You can find a starting point through
      the blog post by Dan [1].

      
      Let me know if you have any additional questions.

    Thanks Mohammed, an informative read. When things have settled
      down a bit at work I'l setup a test volume to attach tiers to.
      Ironically, now we've migrated the production env to gluster, my
      ability to test is lessened  - can't tweak it arbitrarily now :)
    

    Some questions:
    - Does the hot tier replication level have to match the cold
      tier? i.e brick for brick?
    - I presume the files are promoted across all bricks. i.e you
      can't have different files promoted per brick.
    - With sharded volumes its the individual shards that are
      promoted?
    

    thanks,
