Set the Storage Overcommit Level for Linked-Clone Desktops
You can control how aggressively View Manager creates linked-clone desktops on a datastore by using the
storage
overcommit feature. This feature lets you create linked clones that have a total logical size larger than
the physical storage limit of the datastore.
This feature works only with linked-clone pools.
The storage overcommit level calculates the amount of storage greater than the physical size of the datastore
that the clones would use if each clone were a full virtual machine. For details, see “Storage Overcommit for
Linked-Clone Desktops,” on page 90.
