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>
