  • Provisioning volumes docsapp

    When a volume using semi-thick provisioning is created, ONTAP sets aside storage space from the aggregate to account for the volume size. If the volume is running out of free space because blocks are in use by block-sharing technologies, ONTAP makes an effort to delete protection data objects (Snapshot copies and FlexClone files and LUNs) to free up the space they are holding.

    Cohesion also increases as the viscosity of the binder increases, or as the pavement temperature decreases. Additionally, cohesion will increase with increasing binder content, up to a certain point. Past that point, increasing binder content creates too thick a film on the aggregate particles, resulting in loss on inter-particle friction.
