Vmware vmfs deduplication

[cyrilrobert]

Hello

I started in netapp and I am concerned for the management of space with vmware Mon.
Will create a lun with no guarantee of space to recapture the space released by the dedpulication ?
What value do you put the fractional_reserve ?

Thank you.

For VMware LUN the Fractional reserve in the volume should be set to 0.
