All of this tells me that the admin estimates the proportion of physical resources to the virtual resources in the data center before deciding on these limits? But in your FS you mention this use-case also applies to domain admins. DomainAdmins don't have a view of the physical resources today. So this should all be admin only. Can you explain how an admin decides on such an estimate? How does he solve the problem of - I have 2TB secondary storage and 10 accounts with 2 domain admins who can create accounts and define limits ? How many snapshots should I allow per account? How many templates/ISOs one can register? If I expand my secondary storage/ increase compute power in my clusters as an admin. How does it affect the resource limit equation I calculated above? You might want to list out use cases as above. Right now regardless of resource type it seems only CPU resource limit is affected as per the FS. Copy/Paste Error? How does the listResourceLimits API resource type look like post the change? For each role. there's already quite a few numbered resourcetypes - 0 -instance, 1-disks etc. Since this will be admin only: Is there any diff. between a domain-admin updating the resource limit of instances for a user as opposed to an admin doing the same? Do you deal with each update differently. -- Prasanna.,
