thick provisioning (TP)

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

. With thick provisioning, the degree of memory

utilization is much lower because a large area of memory is provisioned but often not used. With thick provisioning, a predetermined area of memory is allocated exclusively to a particular 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 usage.
