• Pool capacity

The license capacity of XP Thin Provisioning is calculated using the total capacity of the

XP Thin Provisioning pool.

◦

◦ If you use V-VOLs of XP Thin Provisioning as P-VOLs or S-VOLs of XP Business Copy/XP

Continuous Access/XP Continuous Access Journal, the license capacity of XP Business

Copy/XP Continuous Access/XP Continuous Access Journal is calculated using the page

capacity allocated to the XP Thin Provisioning V-VOLs (that is, used pool capacity).

For instructions on how to calculate pool capacity, see the HP StorageWorks

XP24000/XP20000 Thin Provisioning Software User Guide.

Estimating Licensed Capacity Based on Mounted Capacity

To estimate licensed capacity based on mounted capacity, convert both capacities to the GB unit.

When converting mounted capacity from TB to GB units, multiply by 1,000. On the other hand,

when converting licensed capacity from TB to GB units, multiply by 1,024.

Table 17 Example A of Estimating Capacity for Purchase

ValueItem

10.3 TB = 10.3 x 1,000 = 10,300 GBMounted capacity

10 TB = 10 x 1,024 = 10,240 GB < 10,300 GB

11 TB = 11 x 1,024 = 11,264 GB > 10,300 GB

Licensed capacity

At least 11 TBEstimated capacity for purchase

As shown in Table 18 (page 47), the required licensed capacity is not always greater than the

mounted capacity. At larger capacities, the difference between the conversion factors (1,000 and

1,024) has a greater (inverse) effect on the equivalent licensed capacity.

Table 18 Example B of Estimating Capacity for Purchase

ValueItem

165.62 TB = 165.62 x 1,000 = 165,620 GBMounted capacity

161 TB = 161 x 1,024 = 164,864 GB < 165,620 GB

162 TB = 162 x 1,024 = 165,888 GB > 165,620 GB

Licensed capacity

At least 162 TBEstimated capacity for purchase

Remote Web Console Options and Licensed Capacity

Table 19 (page 47) lists the options for the Remote Web Console and the licensed capacity type.

Only some of the Remote Web Console options are available to storage partition administrators.

For the available options for storage partition administrators, see the HP StorageWorks

XP24000/XP20000 Disk/Cache Partition User Guide.
