Theoretically whatever you said is correct (at least from shard's perspective).
Adding Rafi who's worked on tiering to know if he thinks otherwise.
It must be mentioned that sharding + tiering hasn't been tested as such till now by us at least.Adding Rafi who's worked on tiering to know if he thinks otherwise.

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