IBM subcapacity regions
Available from 9.2.2.
IBM subcapacity
licensing rules define three regions. To properly calculate subcapacity values for products that are
installed in multiple regions, generate the audit snapshot for each region. Then, for every product,
sum up the subcapacity values from all regions. The value that you obtain is the overall subcapacity
usage for the particular product.
IBM subcapacity regions
- Region 1: North America and South America
- Region 2: Europe and Africa
- Region 3: Asia and Australia
Steps to calculate subcapacity values
- Divide the computers in your infrastructure into groups that reflect IBM subcapacity regions. Ensure that each group contains only computers that are located in one region. Do not create computer groups that overlap as it might distort the obtained results.
- Optional: If software in each region is managed by a different person, create dedicated License Metric Tool users, each with access only to computers in one region.
- Import part numbers for each computer group and bundle software within each region.
- Generate audit snapshots for each region. Ensure that the snapshots cover the same or approximately the same period.
- For every product, sum up the subcapacity values from all regions. The value that you obtain is
the overall subcapacity usage for the particular product.Important: If you generate the audit snapshot for the All Computers group, utilization of subcapacity license metrics might differ from the value that you obtain by summing up values from snapshots generated for each region. Utilization of the subcapacity license metrics for the All Computers group is measured at the time when the sum of metric values from all regions is the highest. However, this value might not reflect the highest metric usage in each region. To comply with the subcapacity licensing rules, you must know what is the highest metric usage in each region, and then sum up these values to obtain the overall metric usage for a product. To better understand the logic, see the example below.
Example
- All Computers
- Region 1: North America
- Region 2: Europe
- Region 3: Australia
- 140 PVUs in Region 1
- 200 PVUs in Region 2
- 140 PVUs in Region 3
- 140 + 200 + 140 = 480 PVUs
Possible setup of the BigFix infrastructure
One BigFix server with three relays
Three BigFix servers
In this case, you set up an infrastructure with three BigFix servers. Each server is dedicated to one IBM subcapacity region and collects data only from the computers in that region. Data from all BigFix servers is imported to one instance of License Metric Tool in which you create three computer groups. Each computer group reflects one BigFix server.
