Be default the snapshots which are taken for any vm are stored with their parent in the same directory or storage. Sometimes you may run out of space and you might not be able to take anymore snapshots so in that case you can always use some other location for the storage of snapshots.Right Click the vm and select Edit Settings
Click on Options from the top TAB, select General and open the Configuration parameters
snapshot.redoNotWithParent
# cd /vmfs/volumes/50925c85-54a206c1-a9e5-d4ae526b9890/test_XP
# vi test_XP.vmx
Save the file and exit
Now you need to reload this vm to make the changes take affect.
# vim-cmd vmsvc/getallvms | grep test_XP
56 test_XP [iSCSI-Datastore15] test_XP/test_XP winXPProGuest vmx-07
Here 56 is the vm id which you can find out using the above command
# vim-cmd vmsvc/reload 56
Now when you take snapshots the snapshot files and vm swap files will be created in a different location.
How to redirect vm's swap file
Add an extra parameter in the Configuration Parameter option shown above
sched.swap.dir="<path_to_vm_directory>"
For example
/vmfs/volumes/50925be7-ea8ab367-d40d-d4ae526b9890/vmswap
