vnx nas
there is a datapool
Datamover and control server
we create a file system on control server
and assign the fs to a datapool
fs will get storage from data pool
and we create quotas under fs
at the quota level we define the actual usage limits
in isilon
we have multiple nodes
and we have only one core file system called /ifs
and all the storage available from all the nodes , mounted to /ifs
and from this , we will be creating share quotas and set usage limits
