Not quite, Hierarchical Storage Management (HSM) has nothing to do with ZCO.

Messages and attachments are moved from a primary volume to the current secondary volume based on the age of the message; completely transparent to the user.
ie: It let's you easily offload data server-side from one storage solution to another automatically based on date; like after say 30 days from your fast SCSI/more expensive solution, and therefore you tend to have less of it. > To a SAN of SATA's or something/usually cheaper, and thus more abundant.
It's nothing that the end-users have to configure; and most would be hard pressed to notice a difference, as they're mostly working with the recent stuff anyway.
ie: Your searches for older stuff in the web-client are just a tad slower, for all intensive purposes practically unnoticeable. It's just the time difference in speed between your SCSI & SATA disks. The same would go for grabbing data with a thick-client, etc.
For that, these are some cool RFE's to track as well:
