5.2.13.7 Total Efficiency LBA Resource Count log parameter
The Total Efficiency LBA Resource Count log parameter of the Logical Block Provisioning log page (see table 322) contains
information about the combined effects of all LBA resource efficiencies (e.g., the result of the combination of de-duplicated LBA
resources and compressed LBA resources).
PARAMETER CODE field
The PARAMETER CODE field is described in 5.2.2.2.1 and shall be as shown in table 322 for the Total Efficiency LBA Resource Count log parame-
ters.
PARAMETER LENGTH field
The PARAMETER LENGTH field is described in 5.2.2.2.1 and shall be set as shown in table 322 for the Total Efficiency LBA Resource Count log
parameters.
RESOURCE COUNT field
The RESOURCE COUNT field indicates an estimate of the number of LBA resources made available by the combined effects of all LBA resource
efficiency methods (e.g., de-duplication and compression) and is defined in 5.2.13.4.2. The algorithm used to calculate this value is not defined
by this standard.
SCOPE field
The SCOPE field indicates the scope to which the RESOURCE COUNT field applies and is defined in table 316.
