This is resource use from my work vCenter 6.7 server running 5 datacenters in three countries with 336 VM's.

This is from my vCenter homelab that I updated to from 6.7 to 7.0 last night running 5 small Linux vms on a single host.

Why does this require half of my 1TB datastore? Is there anything I can do to reduce this massive chunk of storage?
