Did anyone successfully run more than one allocator on the same hardware?

For example one using spinning disks and one on SSD?

If you mean by partitioning the hardware into multiple VMs, then yes I believe that does occur

It's not possible otherwise

Would that be the preferred way (or "best practice") if one had a server to which were attached several types of storage? Since tagging appears to be at the allocator level, how would one meaningfully separate the storage resources when both "SSD: true" and "highstorage: true" is technically the case?

Yes - if you had multiple storage types, ECE forces you to specify a single volume per install, so you should split the server into multiple VMs and treat them as if they were logically separate servers (which then fixes the tagging issue as well, of course)
