Thin_Provisioning

Hi All,

I need to know that If a volume is thin but the contained LUN in it has a space reservation or say is thick then how would ONTAP provision the space.

Regards,

Manish

suppose you have a 100GB volume with one, 50GB LUN in it

- if the volume is thick provisioned, 100GB worth of blocks are set aside (reserved) for that volume by the aggregate

- if the volume is thin provisioned and the LUN has reservation enabled, 50GB worth of blocks are set aside (reserved) for that LUN by the aggregate

- if both, the volume and the LUN are thin provisioned, blocks are provided to the LUN as required/requested (up to 50GB - given that there is enough space in the aggregate)
