How CloudStack handles multiple NFS type Primary Storage  #9067

I have added a second primary storage to my CloudStack which has augmented the storage space in Dashboard. I have gone through the CloudsStack documents and browsed through the Internet but didn't get a precise clue how ACS is managing multiple NFS storages to distribute VM image creation. I didn't find any global parameters either to control this distribution behavior.

Can someone please enlighten me?
