5.2.13.2.2 RESOURCE COUNT field
The RESOURCE COUNT field indicates an estimate of the number of LBA resources expressed as a number of threshold sets for
the threshold resource indicated by the parameter code value. The nominal number of LBA resources is calculated as follows:
LBA resources = resource count × threshold set size
where: resource count is the value in the RESOURCE COUNT field; and
threshold set size is the number of LBAs in each threshold set (i.e., 2
(threshold exponent)
LBAs,
where the threshold exponent is indicated in the Logical Block Provisioning
VPD page).
