We are running vshere 4 with nfs and iscsi datastores on an emc san. The problem I am having is that the thresholds that vmware has seems strange. On one datastore when it get to 91gig free vmware will pause the vm's complaining about free space. On another it started pausing vm's with around 200gig free. Where is this setting at? And how could have the settings been so messed up? I was thinking this happened before on 3.5 and it wouldnt start pausing vm's untill there were only a few meg's left.
