Fractions of points supported for IBM PVU license calculations

Points tables in IT Asset Management have long supported decimal fractions of points used for calculating consumption in points-based licenses. From this release, when IT Asset Management is in PVU mode (responsible for sub-capacity consumption calculations for IBM PVU licenses), it correctly uses any fractional points values in calculating both current and historical peak consumption values. Rounding is not applied (so that fractional values are preserved) throughout device calculations and summing of those consumption figures within the three mandatory IBM regions. Only at the level of reporting by those regions is rounding up correctly applied, as required by IBM. (If you still have not configured those reporting regions, rounding is applied to your global total consumption.) For example, imagine that you have a negotiated points rule where each core earns 0.5 points, and consider one of the standard IBM regions where you have:

• Host1 running VM1 with 3 cores, contributing (3 x 0.5) = 1.5 points to license A
• Host2 running VM2 with 4 cores, contributing (4 x 0.5) = 2 points to license A
• The total consumption in the region is therefore (1.5 + 2) = 3.5 points, which for the regional report is finally rounded to 4 points total.

In contrast, the Consumption tab of the same license properties, which always shows the current result of the most recent compliance calculation, displays any decimal fractions in the contributions of each host to the total consumption of the license.
