    <p>Yes, you are correct. On a sharded volume, the hot and cold would
      be based on sharded chunks.</p>
    <p>I'm stressing the point which Krutika mentioned in her mail that
      we haven't tested the use case in depth.</p>

            It must be mentioned that sharding + tiering hasn't been

                      tiering with sharding usefull with VM workload?<br>
                      Let's assume a storage with tiering and sharding
                      enabled, used for<br>
                      hosting VM images.<br>
                      Each shard is subject to tiering, thus the most
                      frequent part of the<br>
                      VM would be cached on the SSD, allowing better
                      performance.<br>
                      <br>
                      Is this correct?<br>
                      <br>
                      To put it simple, very simple, let's assume a
                      webserver VM, with the<br>
                      following directory structure:<br>
                      <br>
                      /home/user1/public_html<br>
                      /home/user2/public_html<br>
                      <br>
                      both are stored on 2 different shards (i'm
                      semplyfing).<br>
                      /home/user1/public_html has much more visits than
                      user2.<br>
                      <br>
                      Would that shard cached on hot tier allowing
                      faster access by the webserver?<br>
