thick provisioning (TP)

In contrast to thin provisioning is classic memory allocation, thick provisioning or fat provisioning, in which more memory is allocated than is required. It is simply assumed that there is a greater need, which ultimately also arises due to a higher complexity of the data.

With thick provisioning, the utilization rate of storage is much lower because a large area of storage is provisioned but often not used.

With thick provisioning, a predetermined memory area is allocated exclusively to a specific application. This memory area can no longer be used by other applications, regardless of whether the first application uses it or not. It is therefore quite possible that one application does not have sufficient memory capacity available, while another uses only a fraction of its memory space. This increases the cost of storage space and at the same time reduces the effectiveness of storage utilization.
