Got myself a new SC4020 and I'm having a fun time trying to figure this thing out, especially how to calculate space usage.
Per the best practice document I'm supposed to use thick (lazy zeroed) disks. In my environment though there's a lot of development happening so a lot of snapshots on the vms.
A lot of my users will take a snapshot as soon as they get their VM so if I make everything thick I will lose 25gigs at the vmware level right away and won't be able to put as many vms per datastore.
Is there any problem if I go thin provisioned in vmware and end up being thin on thin? In such a case, does VMware become my authority on how much space I have left on the datastore?
